AMPLIFIERS

Thank you and Congratulations

Thank you for your decision to purchase a PowerBass USA Xtreme mobile ampliﬁer! Our new mini ampliﬁers

are the result of extensive engineering, testing, and bullet proof construction. Their versatility enables compat-

ibility with optional signal and audio processors. These high quality MOSFET ampliﬁers may be conﬁgured to

allow maximum ﬂexibility in designing different types of speaker systems.

COMPACT CLASS D AMPLIFIERS

Unlike most Full Range ampliﬁers, these models are designed speciﬁcally for low frequencies and are intended

only to power subwoofers. It is important that you closely follow the wiring instructions contained in this Own-

ers Manual so that you get the most from your PowerBass Xtreme Class D Mono mobile ampliﬁer.

∆ Caution ∆ High powered audio systems in a vehicle are capable of generating higher than “Live Concert” levels of sound pressure. Continued exposure to excessively high volume sound levels could cause hearing loss or damage. Also, operation of a motor vehicle while listening to audio equipment at high volume levels may impair your ability to hear external sounds such as horns, warning signals, or emergency vehicles—thus creating a potential trafﬁc hazard. In the interest of safety, PowerBass USA highly recommends listening at lower volume levels when driving.

• Turn off all stereo and other electrical devices before you begin.

• Disconnect the negative (-) lead from your vehicles battery.

• Locate all fuel lines, brake lines, oil lines, and electrical cables when planning the install.

• Make sure there is at least 2-inches (5 cm) around the air vents on the ampliﬁer.

• When connecting ground points, make sure all paint is carefully scrapped away from the auto body

and contact is make with bare metal.

• Use a utility knife to trim away fabric from hole locations before drilling or cutting.

• When running power cables through sheet metal, be sure to use grommets to properly insulate the

metal edges from the wire insulation.

• If possible, use tubing through grommets.

WARNING: Check your vehicle’s owner’s manual before disconnecting the battery. Disconnecting the battery on some vehicles may require an anti-theft code when reconnecting the battery and require the on-board computer to be reset at the dealership. Check with your local dealer if you are uncertain.

MOUNTING THE AMPLIFIER

Fig.1 Mounting the Ampliﬁer

Due to the high power output of the PowerBass Xtreme Class D ampliﬁers, considerable heat may be produced when the unit is in operation. For this reason the ampliﬁer should be mounted in a location which will allow air to circulate freely. A clearance of at least 2-inches (5 cm) to all sides of the ampliﬁer is necessary not only for proper cooling, but also for gaining access to the inputs and other variable controls. Be sure that the power and signal cable connections can enter and leave the ampliﬁer in a straight line to avoid the risk of kinked wires causing malfunction.

Page 5

MOUNTING LOCATION

The XL Series ampliﬁers have a conformal coating applied to the PC board. This coating makes them resistant to water and dust—however they are not waterproof. Therefore, care should still be taken to protect the ampliﬁer from water and ﬁnd a mounting location that is not likely to get wet. Take care not to mount in a vehicle/ vessel where it can cause interference with the factory installed electronic devices.

The unique wrap around outer shell (heatsink) allows the XL Series ampliﬁers to be mounted in spaces with minimal air ﬂow. It is important that whatever location is selected the ampliﬁer must be mounted securely in a manner keeps the unit intact even during rough jolts that can occur to the vehicle/vessel.

You may use the ampliﬁer as a template and mark the four screw locations with a felt tip pen. Set the ampliﬁer aside before drilling. Use caution to make sure there are no objects behind the installation surface that may become damaged during drilling.

If mounting under a seat, make sure there is at least 1-inch (2.5 cm) of space above the ampliﬁer’s heatsink to permit proper cooling.

The best places to mount your ampliﬁer are: The ﬂoor of the trunk, under a seat, or on the back of the rear seat. For alternate installation locations, please consult your authorized PowerBass Dealer.

NOTE: Do not use a drill with driver bit to mount the ampliﬁer. Excessive force could cause the plastic mounting feet to crack.

*** WARNING ***

• Do not install in a place where it could injure the driver or passengers if the vehicle stops suddenly.

• Try to avoid mounting the ampliﬁer on a subwoofer enclosure, as extended exposure to vibration may cause malfunction of the ampliﬁer.

• Don’t mount the ampliﬁer so that the wire connections are unprotected or are subject to pinching or damage from nearby objects.

• The DC power wire must be fused at the battery positive (+) terminal connection. Before making or breaking power connections at the ampliﬁer power terminals, disconnect the DC power wire at the battery end.

• The battery of the car audio system must be disconnected until the entire wiring and installation is completed.

CONTROL PANEL LAYOUT

Fig.2 Panel Layout

NOTE: Panel Layout and Controls may differ by model.

1. POWER/STATUS Indicator

This clear LED lights Blue when the power is on—or turns Red constantly when the built-in protection circuitry is activated. Red indicates a problem with the system in relation to the ampliﬁer (See Troubleshooting Tips).

Page 7

2. REMOTE LEVEL

This is the connector port for the Remote Level Control. Now the ampliﬁers secondary gain circuit can be adjusted from the driver’s seat.

3. LPF (Low Pass Filter) Control

This ﬁlter controls low pass of frequencies and is adjustable from 50Hz through 250Hz to eliminate unwanted high frequencies.

4. BASS EQ Control

This equalization circuit is used to enhance the low frequency response of the vehicle’s interior. With up to 18dB of boost centered at 45Hz, the BASS EQ can be adjusted to meet your own personal taste.

5. SUB SONIC Control

This control is continuously adjustable from 15Hz through 50Hz at 12dB per octave to provide an extra level of speaker protection from bass robbing power at unheard frequencies.

6. GAIN Control

This control is used to match the input sensitivity of the ampliﬁer to the particular source unit that you are using up to 6 volts.

7. AUX Input Jack

This 1/8-inch (3.5mm) mini jack can be used to accept an MP3, iPOD or smartphone as the source unit from that device's headphone (3.5mm) output.

8. LOW INPUT

Use this Low Level 4-pin Molex style input is where the wiring harness plugs in for the Low Level input that connects to source units with RCA line level outputs. A source unit with a minimum input of 250mV is required for proper operation. However, this input can accept levels up to 6Vrms.

9. GND (Ground Input Connection)

A good quality ground is required for your PowerBass Xtreme ampliﬁer to operate at peak performance. A short length of cable the same gauge as your power cable should be used to attach the ground terminal directly to the chassis of the vehicle. Make sure that all of the paint is sanded or scraped away to ensure a quality ground connection.

10. REM (Remote Input Connection)

All PowerBass Xtreme ampliﬁers can be turned on by applying 12 volts to this terminal. This can be found on the rear of the source unit in the form of an electronic antenna output, or a remote output. If this is not available you can wire to the ACC position on the key. An 18 gauge wire is sufﬁcient to run the REMOTE.

Page 8

11. BATT+ (Power Input Connection)

This terminal is the main power input for the ampliﬁer and must be connected directly to the positive (+) terminal of the car battery. The solderless terminal block is designed to accommodate up to 4-gauge power wire.

FUSE-IMPORTANT

Due to the limited space on the XL ampliﬁer chassis they do NOT come with internal fusing! Instead we have included an in-line fuse holder that can be connected directly to the BATT+ input on the ampliﬁer. Please note the proper ampere fuse for each model are listed below. Never replace a fuse with a higher rating then what is listed.

XL-350DM 40A XL-600DM 60A

12. SUBWOOFER OUTPUT

This 4-pin Molex style connector is where the speaker output harness plugs in. Be sure to observe the correct speaker polarity and follow the speaker wiring diagrams found elsewhere in this owners manual.

POWER WIRING AND SIGNAL CONNECTIONS

*** WARNING ***

Disconnect the negative (-) battery terminal before you start any wiring work! The battery of your car audio system must be disconnected until the entire wiring installation is completed.

Your PowerBass Xtreme Class D amp will draw large levels of current, so use the largest gauge power/ground cable as possible. Using too small of power cable can result in unnecessary over-heating of the ampliﬁer, distortion at high volume levels and might even cause the thermal protection circuitry to shut-off the ampliﬁer. Remember, bigger wire is better!

• Use rubber grommets when running cables through any metal or sharp plastic, to prevent accidental shorting or shearing. Make sure the cables do not interfere with normal operation of the vehicle.

• The audio signal cables (RCA interconnects) should be kept far away from any potential sources of electrical interference such as electronic vehicle management systems (relays, engine computers wiring harnesses, fuel pumps etc.)

Fig.3 Power Input Connection

This ampliﬁer is designed to work within a 9-16 volt DC range. Before any wires are connected, the vehicles electrical system should be checked for correct voltage supply with the help of a voltmeter.

First, check the voltage at the battery with the ignition in the OFF position. The voltmeter should read no less than 12V. If your vehicles electrical system is not up to these speciﬁcations, we recommend having it checked by an auto electrician before any further installation. Once the vehicle is checked, make certain the correct cable gauge is used. We recommend using as large a gauge cable as possible, use the Power Cable Selection Chart to calculate the correct power wire size for your application.

Page 10

POWER WIRING

BATT+ (Power)

This ampliﬁer should be wired directly to the vehicle battery using the appropriate size cable. Start at the vehicle battery and run the power cable through to the ampliﬁer. Avoid running the power cable over engine components and near heater cores. The use of an inline fuse or circuit breaker is a must; this will prevent the risk of a potential ﬁre caused by a short in your power cable. Connect the fuse holder or circuit breaker as close to the battery positive (+) terminal as possible (no farther then 18” from that battery). This fuse or circuit breaker should be no greater then the sum of the fuses found on the chassis of your ampliﬁer (also see speciﬁcations chart). You may now connect the cable to the battery, but remember to leave the fuse out or circuit breaker “off” until all other cable connections are made.

GND (Ground)

When grounding your ampliﬁer, locate a metal area close to the ampliﬁer that is good source of ground (preferable the ﬂoor pan). Once again, investigate the area you wish to use for electrical wires, vacuum lines, and brake or fuel lines. Use either a wire brush or sandpaper to eliminate unwanted paint for better contact of the ground. Secure the ground cable to the body using a bolt, star washer and nut. Spread silicon over the screw and bare metal to prevent rust and possible water leaks.

Fig.4 A Proper Ground Is A Must !

Now it’s time to connect the power and ground cables to the ampliﬁer. Cut both cables to length. Strip off 1/2 inch (12mm) of the insulation so that the bare wire ﬁts all the way in the terminal block on the side panel of the ampliﬁer, seating it ﬁrmly so no bare wire is exposed. Use an Allen wrench to loosen the BATT+ and the GND connections on the ampliﬁer. Insert the ground ﬁrst, and then the +12V and please make sure that you place them into the correctly marked terminals. Then tighten the screws down securely by hand.

Page 11

REM (Remote Trigger)

This terminal must be connected to a switched +12V source. Typically, remote turn-on leads are provided at the source unit that will turn on and off the ampliﬁer in correspondence with the source. If the source unit does not have a remote turn-on lead, then a power antenna wire can be used. If neither of these leads is available at the source unit, then a switched +12V supply must be used, like the ACC, +12V. Run a minimum of 18 gauge wire from the ampliﬁer location to the source of the switched +12V lead. If possible, route this wire on the same side of the vehicle as your power cable. Connect the source remote output to the wire. Go back to the ampliﬁer and cut the wire to length. Loosen the screw terminal marked REM on the ampliﬁer. Insert the stripped (bare) portion of the wire into the terminal and tighten the screw securely.

FUSE REQUIREMENTS

Due to the small size of the PowerBass XL series ampliﬁers, no fuses are incorporated into the panels that normally protect the unit from excessive current. Instead we have included a wired loop in-line fuse holder and fuse for this purpose.

Cut the red wire loop and strip back ½-inch (13mm) of insulation from each end.

Insert one end of the red wire directly into the BATT+ terminal of the ampliﬁer and secure it by hand tightening the hex screw.

Splice the other end of the red cable into the power wire you are wiring to the battery. Remember this fuse does nothing to protect the vehicle/vessel from a dangerous short circuit.

It is absolutely vital that the main power lead to the ampliﬁer(s) in the system be separately fused within 18-inches (45cm) of the connection to the battery. The value of this additional fuse (or circuit breaker) should be no greater than the sum of the fuses found on all the equipment being connected to that power wire.

RCA INTERCONNECT WIRING

Fig.6 Low Level Input using RCA

Traditional radio setup

Choose the correct length and style of RCA interconnects for your needs. Always use high quality RCA audio cables (not supplied) for signal connections—those with multiple layers of shielding or a twisted pair variety for better noise rejection.

Be extra careful when routing your RCA audio interconnect cables. Car environments are notorious for poorly insulated wires. This means that hiss, engine noise, and fan noise can easily be picked up through RCA cables if run incorrectly.

Make sure that the cables for power and audio signal are not on the same side of the vehicle and that they do no cross each other; this will help reduce any noise that may radiate from the power cable and the signal cable. If an audio cable is too close to a power cable, it may pick up the magnetic ﬁeld generated by the power cable, which could lead to a loss of quality in your signal.

Page 13

AUX INPUT WIRING

Typical 2 ampliﬁer setup

Fig.7 AUX Input using 1/8" (3.5mm)

MP3 or Portable Device as a Source

The XL Powersport Series ampliﬁers all feature a AUX source input. This allows you to substitute a portable music device such as an iPOD, Smartphone, MP3 Player, etc instead of a traditional radio as your music source. Above is a typical two ampliﬁer system—a multi-channel ampliﬁer (our 2-channel XL-2200M or our 4-channel XL-4160M) to power the full range speakers and a mono bass ampliﬁer (our mono XL-350DM or XL-600DM) to power the subwoofer(s).

You will need to use a quality shielded 1/8-inch (3.5mm) stereo male to male audio cable and “Y” adaptor (not supplied) for this type of set up. Route the shielded audio cable using the same care as you would with the RCA interconnect for a traditional source unit.

NOTE: A side panel AUX Input is available for use with portable MP3 players or an iPod ®* Use of this input will override (defeat) the RCA low level inputs.

SET UP ADJUSTMENTS

Input GAIN Adjustment

GAIN

MINMAX

Fig.8 GAIN Control

This control allows you to match the input level of the ampliﬁer to the output level of your head unit. Matching the input can be accomplished in four simple steps:

1. Make sure that the remote level control is not plugged in until after the master gain control is set.

2. Set the GAIN control on the ampliﬁer to Min (completely counter clock wise).

3. Turn on the head unit and adjust volume to 2/3 maximum, and set the BASS and TREBLE to zero.

4. Adjust the GAIN control clockwise until the sound just begins to distort, then back off slightly to cut distortion and operate at optimum gain.

Remember, the GAIN control is not a volume control. Ignoring these steps above may leave you with damaged speaker and/or a damaged ampliﬁer.

SUB SONIC Adjustment

The subsonic ﬁlter is a 12 dB/octave high-pass ﬁlter, with a fully variable cutoff frequency between 10 - 50 Hz. When set at frequencies lower than 30 Hz, it conserves ampliﬁer power without audibly affecting the quality of the sub-bass output.

LPF (Low Pass Filter) Adjustment

The crossover frequency adjustment ﬁlters out frequencies that you don’t want your subwoofer(s) to reproduce. Using the LPF control, adjust the Low Pass Frequency to limit the amount of mid range you want going to your woofer(s). Since musical tastes vary, adjust the crossover by ear while listening to the music of your choice. Be sure to set the tone controls of your source unit to ﬂat before adjusting the crossover.

Fig.11 Bass EQ Control

BASS EQ Control

This special feature is designed to provide you more powerful sound quality, and it allows you to increase the bass output up to +18dB at 45Hz. Keep in mind that more is not always better. Setting the control to the max (18dB) will stress the ampliﬁer and the speakers and could result in damage.

NOTE: More is not always better. By turning the BASS EQ all the way up to +18dB you can overwork the ampliﬁer and send the unit into thermal protection.

Fig.12 Connection with RJ25 Jack

REMOTE LEVEL Controller Connection

Your PowerBass Xtreme Class D amp includes a Remote Level control module. It uses standard telephone wire and telephone RJ25 connectors. To connect the Remote Level Control to the ampliﬁer, simply insert one end of the 6-pin telephone plug into the REMOTE LEVEL port. Plug the other end into the remote module. Install the module within easy reach on or under your dash.

SPEAKER WIRING AND CONFIGURATIONS

Bridging

Although the XL-350DM and XL-600DM have two sets of subwoofer outputs, they are mono and the outputs

cannot be bridged. The two sets of outputs are in parallel inside the amp to a single channel. This allows

easier wiring during the installation of multiple voice coils or woofers.

NOTE: Know your total impedance load before you make any connections.

WARNING: Do not try to bridge the speaker outputs of one ampliﬁer by itself. The two sets of

speaker output terminals are internally paralleled on the circuit board of the ampliﬁer. This means

if both outputs are used with one driver each, the ampliﬁer sees the same load as if the same two

drivers were connected to only one output terminal. It should also be noted that two of these am-

pliﬁers cannot be strapped together even if they are the same model number. Doing so will cause

the ampliﬁers to malfunction.

The subwoofer outputs on this Class D ampliﬁer are internally paralleled and are NOT to be bridged. The

speaker’s impedance is divided between both outputs.

Page 17

Speaker Load

Keep in mind your PowerBass Xtreme Class D ampliﬁer is a High Power Ampliﬁer and not a high current

ampliﬁer. In other words it requires a minimum impedance of 2-ohms (1-ohm for the XL-600DM). Both sub-

woofer outputs are internally paralleled, thus a minimum impedance of 4-ohms (2-ohms for the XL-600DM)

is required when using more than one of the subwoofer outputs. If you are unsure of calculating impedance

loads please consult your PowerBass Xtreme dealer before damaging your ampliﬁer.

Too low of an impedance could send the ampliﬁer into protection mode and/or permanently damage the

ampliﬁer.

• Check for signal on the RCA cable with VOM in AC po-

sition

• Advanced Protection Circuitry is engaging due to high internal temperature of the ampliﬁer. Amplifer requires more air ﬂow around the chassis. If this continues choose a better ventilated mounting location.

• High operating temperature can be caused by incorrect input sensitivity level. Reset the GAIN contol.

• Thermal protection is engaged. Check for proper impedance at speaker terminals. Also check for adequate air ﬂow around the ampliﬁer.

• Voltage protection engaged. Voltage to the amp is not within the 9-16 VDC operating range. Have the battery/ charging system inspected.

• Short circuit protection is engaged.Check for speaker wires shorted to each other or the vehicle chassis. Speakers operating below the minimum impedance can cause this to occur.

• Check for damaged RCA cable.

• Check routing of RCA cable

• Check Source Unit for good ground

• Check amp gain setting, turn down if set too high

• Check speaker polarity, reverse the connection of one

speaker only.

NOTE: If the Status L.E.D. is activated and glows RED with no speakers connected to the ampliﬁer, and all the power connections are correct, this would indicate an internal problem with the ampliﬁer. Contact PowerBass USA or your local dealer.
