But, should you choose to install these products yourself, please take the time to read this manual completely and abide by all precautions.

PCA AMPLIFIER BENEFITS & FEATURES

There is a constant push for entry level amps to “play with the big dogs” yet for a low price point. Rarely are they able to do so…. until now.

Rock solid Class AB designs ensure “in your face” sound with little fear for reliability or performance. The rugged designs of the PCA amp line,

and their remarkable input frequency and gain setting flexibility, enable nearly any system configuration. Fat power and speaker leads make sure all that power going in comes out the best sound possible.

Should something go wrong in the installation, have

no fear. Protection for output short circuits and short to grounds or 12 volts are all covered and a safety “Protect” light lets you know. Peace of mind, and big power, at low price points…look no further.

•Real, RMS watts. No need for “bogus” watts. This is the real stuff in a great amp so there is no need to exaggerate - it does what it says.

•Reinforced Class AB designs with reinforced output stages ensure solid performance and reliability.

•Big heat sinks to ensure adequate heat dissipation regardless of the load (they look cool too).

•Monster size, gold plated power and speaker terminals for reliable, low resistance connections.

•Protection LED for notification should the unit shut down due to installation problems.

SAFETY CONCERNS

We always recommend you have your Blaupunkt amplifiers professionally installed but the installation process is often so easy that the average consumer can achieve success with little trouble. Regardless of the person installing, you should be sure to review the following points before proceeding with the installation:

■READ THE MANUAL! Understanding the product and installation limitations before lifting a screwdriver.

■WEAR SAFETY GLASSES AT ALL TIMES - Flying debris are always dangerous.

■PROTECT THE VEHICLE - Always disconnect the negative battery cable before starting any kind of installation work. This prevents a possible high current electrical short (potential fires).

■HEAT - Keep all audio components away from nearby hot vehicle components that heat up over time such as hoses, high current wires, and braking system components.

■GIVE YOURSELF LOTS OF TIME - Rushing to complete an installation nearly always ends up with problems.

■DO NOT LISTEN AT HIGH SOUND LEVELS FOR A PROLONGED TIME - these amplifiers, used with high efficiency speakers from ANY manufacturer, have the potential to cause permanent hearing loss after listening at maximum volume levels for several hours.

INSTALLATION WARNINGS!

Before disassembling your beautiful new car you need some basic installation knowledge and skill with common hand and power tools. Following such basic installation tips and warnings will prevent possible damage to the vehicle and also prevent possible fires.

■AGAIN...READ THE MANUAL! There is a lot of helpful information in this manual that will save time and prevent problems later.

■COVER THE VEHICLE WORK AREAS - Use fender covers or blankets to protect the work areas from scratches or dings.

■DISCONNECT THE (-) LEAD ON THE BATTERY - No sparks or fires please!

■“REVIEW” THE INSTALLATION - Before using any tools or moving vehicle components, take five minutes to review the installation intentions (e.g., verify that an amplifier will fit in an area of a car before tearing out all the interior).

■“REVIEW” THE VEHICLE - Before drilling any holes or cutting into any surfaces, make sure there are no fuel or hydraulic lines behind the surfaces. Also make sure there are no wires routed directly behind or near the desired mounting area (remember...screws can often extend 1-2 inches behind the mounting surface).

■ENSURE PROPER FIT - Before cutting or drilling, make sure the amplifier will physically fit in its desired location. Check for clearance around rear deck torsion bars or other structural elements.

■EVERY CAR IS ASSEMBLED DIFFERENT - Every auto manufacturer uses different

assembly techniques. Take care in removing/modifying all trim panels and mounting surfaces since they often use unique screws or snap fasteners that are difficult to replace if they are lost or broken.

■BE CAREFUL WITH CABLE ROUTING - When routing audio cables, make sure RCA and speaker wires are routed away from high current power lines for audio amplifiers and vehicle systems lines when possible. This will help prevent noises from creeping into the audio system, plus prevent potential damage to the vehicle wiring itself.

■BE CAREFUL WITH ALL CONNECTIONS - When making connections, make sure each connection is clean and properly secured. Observe all polarity markings carefully to ensure proper end performance.

■CAUTION - FUEL TANKS AND FUEL LINES ARE NOW LOCATED DIRECTLY BENEATH THE REAR DECK IN MANY CARS - CHECK FOR ADEQUATE CLEARANCE BEFORE EVEN CONSIDERING SUCH A MOUNTING LOCATION!

SYSTEM PLANNING

Before wiring up an audio system that may not achieve the sound quality you want, be sure to choose a system concept that fits your listening requirements. Basic systems, a receiver with internal 4x20 watts and 4 coax speakers, are adequate for many listeners. But, when you want to really “feel” the music, you will need some kind of subwoofer amplifier/speaker combination. Although many people might jump into an “add-on” amplifier to power to rear coaxial speakers, a better choice is usually a subwoofer amp/speaker system that supplements the existing 4 speaker system as shown in the adjacent drawing. Such a system provides a surprising improvement in sound quality due to the usually dramatic increase in bass response.

The next dramatic step up in performance is with a “multichannel” system that offers more dynamic range in the mids and highs due to higher power plus more bass response due to multiple woofers and/or more power. But, with such a system, the stereo image and overall listening experience usually becomes much more life-like due to better tonal quality midrange/tweeter speakers and usually better placement.

To build such a system though, complexity goes up due to the addition of passive or active crossovers which take time to install and may inject noise into the system due to potential noise signal pick up. The results though of such a system can be dramatically pleasing.

INSTALLATION TOOLS

For most installations, simple hand tools are adequate to install an aftermarket amplifier. Depending upon the mounting locations used, you will need power tools for drilling and cutting plastics and metal. A good starting list is summarized below:

Tape measure and ruler Marking pen and starting punch

Phillips and flat blade screwdrivers (small and medium sizes) Nylon wire bundle ties

Pliers: standard vice-grip and needle nose styles Light-duty trim pry-bar for removing door trim

Cutting shears or nibbling tool for cutting thin and medium gauger metal

Wire cutters, wire strippers, electrical tape, crimping pliers and appropriate crimp-on terminals

■ Power drill with appropriate sized drill bits

VEHICLE WIRING

VEHICLE FUSING

For safety purposes, a high current fuse (or circuit breaker) MUST be installed in line with the amplifiers(s) immediately at the battery to prevent vehicle damage should the battery line in advertently shorted to the vehicle chassis. The chart at the right shows the recommended master fuse sizes for an average audio system with noted “rms” output power levels.

SYSTEM FUSE CHART

Fuse Size	20 A	30 A	50 A	100 A
(in amps)

POWER WIRING

Most vehicles built since 1990 have adequate current capability for your amplifier. Except for systems above about 500 W rms, the factory charging system and battery should easily support it if properly installed. Proper wire size must be chosen to ensure adequate current delivery to the amp. Wire size (gauge) of the cables need to increase in size for higher power systems. (Wire sizes larger than those noted are usually a waste of time and money since they offer Little or no performance improvements.)

Wire diameter must increase (decreased wire gauge number) for higher power systems. For long wire runs the wire diameter must also increase. The wire sizes noted allow for a maximum 0.5 volts DC drop over the give wire run which results in Sound Pressure Level drops inaudible to the average listener.

SPEAKER WIRING

As with power wire, speaker wire size (gauge) changes with the power required and the length of the wire run. The speaker wire chart shows the minimum recommended wire size for a single audio output channel driving a loudspeaker at a given distance with a maximum power loss of 0.5 dB, the threshold of audibility. (Wire sizes larger than those noted are usually a waste of time and money since they offer little or no performance improvements.)

20 ft. / 6.0 m	16	16	16	14
25 ft. / 7.5 m	16	16	14	12

FINAL VEHICLE WIRING

Current requirements for an upgraded audio system dictate a dedicated power line be run from the amplifier directly to the battery of the vehicle. This line should NOT be run to the fuse panel of the vehicle but directly to the battery. DO NOT run to the alternator either. There MUST be a fuse installed at the battery with adequate amperage as shown in the chart above.

As for the final signal wiring, be sure to route the audio cables down the side of the car opposite the power lines to avoid noise pick up from the lines. Also, try to route all audio cables away from noise sources such as engine computers and ABS brake computers.

POWER CONNECTIONS:

GROUND - This is the high current ground connection to the chassis of the car. It should be fastened to a clean ground connection in the vehicle, capable of handling high current loads. This wire should be no longer than 3 feet (1 meter)

+12v - A high current line run direct from the batter is highly recommended to insure adequate current and voltage. This line MUST be run through a dedicated fuse of some kind and this fuse should be located immediately next to the power source. This in-line fuse is used to protect the vehicle should a short to chassis occur.

TRIGGER - This line tells the amp to turn on and is remotely switched from the radio which normally provides an amp “trigger” output. This line is required to go “high” (+12V) to turn on the amp. If this line is not available, use the power antenna line trigger which is normally available in most radios.

FUSE - This fuse is only for catastrophic situations should the amplifier begin to self-destruct or incur installation situations where gross amounts of current are being required from the amp beyond its design limits. Although another fuse should be installed inline with the high power line at the battery, this amplifier mounted fuse MUST remain in the circuit to protect the amplifier.

SPEAKER OUTPUTS - The amplifier is connected to appropriate impedance speakers via these leads. It is IMPERATIVE that these leads NOT be connected or touch the vehicle chassis in any way or the amplifier will be damaged. The (+) and (-) leads of the amp are in no way inter-connected to one another. Also, NONE of the leads can touch each other, touch ground, or touch +12V or damage may occur to the amp or vehicle.

LINE LEVEL INPUTS - The most commonly used inputs in the aftermarket world are RCA type line level inputs. These inputs can handle up to about 6 Volts rms without overdriving the amplifier. Such high voltages are rarely found from car audio head units so this is a very comfortable value. But, should the use need to drive the amp directly from speaker level leads, use the supplied “High Level Adapter” to connect to the amp.

POWER ON LED - This light will turn on when the amplifier receives a +12V turn on signal from the radio. If the amp is properly wired, but the light does not turn on, there may be a short circuit condition that the amp is protecting itself from.

PROTECTION LED - This light turns on if the amplifier senses a severe problem, such as a speaker short circuit.

BASS BOOST - This control provides additional bass in the 45Hz area to give a stronger low end “feel” to the bass. Once switched on, this will also allow the amp to be driven into distortion sooner so the user must be aware.

GAIN CONTROL - The gain control allows for a range of 0.3-6Volts input. This means that if the setting is a 0.3V, it only takes 0.3Volts to drive the amp to full output. (Such a low setting allows for the amp to be easily overdriven and more susceptible to noise so a mid-position is highly recommended for most radios.)

LOW-PASS FREQUENCY - If the mode selector is in the “LP” position the amplifier passes only low frequency sound. The upper limit for such sound is set via this control. For bass, a value just below 100Hz is usually best.

HIGH-PASS FREQUENCY - If the mode selector is in the “HP” position the amplifier passes only mid and high frequency sound. The lower limit for such sound is set via this control. A common setting is just above 100Hz.

CROSSOVER MODE - Depending upon the system design chosen, you need to set the amplifier in the proper “mode” be it LP, Flat, or HP. The low-pass and high-pass frequency settings are explained above. The “Flat” setting simply allows for the amp to pass all audio frequencies without any kind of crossover filter application. (This is common with 6x9” fullrange coaxial speakers for example.)

2 Channel Full-range -or- High-Pass Mode

This installation is most popular for listeners who want to simply increase the power to the rear speakers in a car. The resulting performance is most commonly a louder overall sound field from the rear.

But, such a system’s biggest benefit is the additional bass response since the bass control of the radio can be turned up without distorting the amplifier. Such a system is not necessarily louder in the mids and highs but is able to play louder in the low frequencies due to this additional power. This leads to an overall richer and stronger sound experience for the listener without additional subwoofer boxes or electronics that may complicate the system or take up more room. Such a system WILL NOT equal the performance of a subwoofer system but will certainly be a pleasant improvement.

With the addition of a high-pass filter, this amplifier is set up to complement a dedicated subwoofer amplifier/speaker system. This allows for smaller (e.g., 5" or 6") satellite speakers to operate most efficiently without being over-driven in the bass region where a dedicated subwoofer system operates most efficiently.

3 Channel Multi-Mode (Passive)

The multi-mode system is a “poor-man’s” satellite/subwoofer system. This amplifier is able to drive speakers in stereo mode and at the same time drive low frequencies to a dedicated subwoofer speaker. By inserting inductors (coils) and capacitors, the result is an inexpensive solution to generating a ‘3' channel system with a 2 channel amplifier.

Using passive components (coils and capacitors) the installation is

simple and performs adequately for most listeners. Such a system will not perform as well as an “active” system because the slow attenuation (roll-off) of the frequency response resulting in a moderate amount of over-lapping of the sound spectrum between the satellites and subwoofers. It is important to remember that although surprisingly pleasant performance is achieved, this is a compromise system and will NOT perform as well as a dedicated 3 channel system with electronic crossovers.

2 Channel Dual Subwoofer Mode

The largest improvement in sound quality always comes when

adding some kind of subwoofer via a dedicated subwoofer amplifier and electronics crossover. The electronic crossover ensures minimal overlap of the bass response with the mid and high frequencies from the other speakers resulting in a more accurate performance compared to conventional coaxials with additional power.

By installing this amplifier in the stereo mode, you are able to drive two subwoofer speakers and in to low impedance loads (e.g., 2 ohms) without over heating the amplifiers. Also, such an installation more easily supports a standard 2 speaker woofer box that may already be constructed. Since two woofers can play 6 decibels louder than one at a given power (due to acoustical laws of “mutual-coupling”), the resulting sound pressure level is substantial. This is probably the most common use for a conventional two channel amplifier there is.

1 Channel Bridged Subwoofer Mode

By electrically connecting a subwoofer speaker in the way shown above, you are able to greatly increase the output power delivered from the amplifier to the speaker. Such a circuit increases the voltage “swing” across the speaker which increase the power seen by a factor of 2 to 4 times that in stereo mode.

For higher output, you can connect a subwoofer to two output channels. Look for the + and – to indicate the correct connections.

4Ω (main)

This is a very logical set-up for systems that are space limited to allow for only one subwoofer in a vehicle. The number and box volumes are compensated by simply more amplifier power pushing a single speaker.

Such a configuration is also a surprisingly good performer. These increases in power are always welcome but you must take care to avoid low impedances (below 4 ohms) since most amplifiers will overheat and shut down if over-driven into such a configuration. You must also take care that you are not exceeding the thermal, or excursion, power limiting values for the woofer. Surprisingly high power levels can be achieved with such a system without realizing it thus quickly damaging the woofer.

TROUBLE-SHOOTING GUIDE

Below is a basic trouble-shooting guide to assist in seeking out and correcting a problem that may occur in the installation process. Although lengthy, this chart cannot address every single problem possible but mainly the ones most common.

SYMPTOM	PROBABLE CAUSE OR CORRECTION
No power (power light not on)	■	Check connections to amps +12 volt, ground, and remote lines.
	■ Use voltmeter to verify voltages are at terminals of amp.
	■	Check main power connection at battery.
	■ Check fuse in power line at battery.
	■ Disconnect all speakers but not power lines - if unit then turns on, a speaker short
		or speaker line touching vehicle chassis is likely.
Power but no sound (power light is on)	■	Check all input cable lines for connection.
	■ Disconnect speakers from amp, test speaker lines with digital voltmeter to verify >2
		ohms per channel (non-bridged mode).
No sound from one channel or entire side	■	Check radio’s balance and fader control positions - verify they are at center.
	■	Check speaker connections at amp and speaker.
	■	Check input leads for connection to amp.
Very low sound level	■	Verify radio balance and fader controls are at center positions.
	■ Check amplifier’s input gain control setting - adjust for higher output levels if
		necessary (gain settings closer to 0.3 volts).
	■ Receiver may have very low output voltage levels - a step up “line driver” may
		have to be used.
Power amplifier turns on and off repeatedly	■	Make sure power connections at batter are tight.
(motor-boating sound)	■	Verify battery voltage is >11.5 volts DC (12.5-15V engine on) at amplifier with engine off.
	■ Check all radio and amplifier ground connections.
Amplifier turns off during loud or distorted	■	Input stage being over-driven - lower input gain (closer to 4 volt setting).
passages	■	Verify battery voltage is >11.5 volts DC at amplifier with engine off.
	■ Check all radio and amplifier ground connections.
	■	Verify speaker loads >2 ohms on all channels (non-bridged mode).
Amplifier performs fine but gets very hot to	■	Input gain control too high - lower accordingly (closer to 4.0 volt setting).
the touch	■	Verify speaker loads >2 ohms on all channels (non-bridged mode).
	■ Verify the mounting location allows for free air movement around the amp.
		Preferably, the amp should be mounted with fins up and down so rising heat moves
		quickly away from amp.
Amplifier turn-on/turn-off pops or noises	■	“turn on race” - disconnect trigger from radio and turn on/off via a wire jumper to
		power terminal. If noise goes away, the radio is turning on/off too slowly. This is
		radio problem and can only be corrected with outboard turn-on delay relay system.
	■	Radio “thump” - disconnect the RCA input lines to the amp and turn on/off via radio
		trigger. If noise goes away without RCA lines connected, the radio is sending pops
		out through RCA lines. This is a radio problem and can only be corrected with
		outboard turn-on delay relay system.
