Thank you and Congratulations

Thank you for your decision to purchase a PowerBass USA Autosound mobile ampliﬁer! Our Autosound ampliﬁers are the result of extensive engineering, testing, and bullet proof construction. Their versatility enables compatibility with optional signal and audio processors. These high quality MOSFET ampliﬁers may be conﬁgured to allow maximum ﬂexibility in designing different subwoofer options.

CLASS AB Mono Block AMPLIFIERS

Unlike most Full Range ampliﬁers these models are equipped with a Low Pass Filter control (LPF) that when engaged is intended only to power subwoofer(s). It is important that you closely follow the wiring instructions contained in this Owners Manual so that you get the most from your PowerBass AutoSound A/B Class Mono Block mobile ampliﬁer.

∆ Caution ∆ High powered audio systems in a vehicle are capable of generating higher then “Live Concert” levels of sound pressure. Continued exposure to excessively high volume sound levels will cause hearing loss or damage. Also, operation of a motor vehicle while listening to audio equipment at thigh volume levels may impair your ability to hear external sounds suck 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.

INSTALLATION EXPERIENCE

Installation of PowerBass mobile ampliﬁers requires detailed knowledge of electronics wiring and proper speaker impedance. We strongly recommend installation by an authorized PowerBass dealer. This Owners Manual only provides general installation and operation instructions. If you have any reservations about your installation skills, please contact your local PowerBass dealer for assistance.

IMPORTANT : This ampliﬁer is designed for operation in vehicles with 12-volt Negative ground electrical systems only.

PREPARING FOR INSTALLATION

NOTE: The tools listed below may be required for basic installation

• An electric drill with bits

• Philips head and standard screwdrivers

• Wire strippers

• Crimping tool

• VOM (electronic volt ohm meter)

• Heat shrink tubing and heat gun

• Soldering iron

INSTALLATION PRECAUTIONS

NOTE: Proceed only if you are a qualiﬁed installer, otherwise; see your Authorized PowerBass Dealer to professionally install this ampliﬁer. Always wear protective eyewear when using tools.

• 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.

Due to the high power output of our PowerBass Autosound 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.

MOUNTING THE AMPLIFIER

MOUNTING LOCATION

Find a clear and well ventilated area to mount your ampliﬁer that is unobstructed by any objects that will cause harm or block ventilation. You may use the ampliﬁer as a template and mark the four screw locations with a felt tip pen. 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 ampliﬁer should be protected from exposure to moisture and direct sunlight. The best places to mount your ampliﬁer are: The ﬂoor of the trunk, under the driver’s seat, or on the back of the rear seat. For alternate installation locations, please consult your authorized PowerBass Dealer.

*** WARNING ***

• Upside down mounting will compromise heat dissipation through the heatsink and could engage the thermal protection circuit.

• 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.

1. Line OUTPUT (RCA) Jacks RCA style pass through output jacks allow for a signal to be sent to other ampliﬁers in a daisy-chain conﬁguration. Only one Remote Bass Control can be used when multiple bass ampliﬁers are connected.

2. Line INPUT (RCA) Jacks These RCA style input jacks are for use with source units that have RCA line level outputs. A source unit with a minimum output of 500mV is required for proper operation. However, this input will accept levels up to 4Vrms.

3. 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 4 volts.
