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.

D CLASS MINI AMPLIFIERS

The PowerBass XAX Series are high quality MOSFET ampliﬁers that are capable of running a system full range,

or they may be selected only to power subwoofers. It is important that you closely follow the wiring instructions

contained in this Owners Manual so that you get the most from your PowerBass Xtreme 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 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.

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 Own-

ers 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

• Electronic (not Acid Core) Solder

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 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.

Fig.1 Mounting the Ampliﬁer

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.

The ampliﬁer should be protected from exposure to moisture and direct sunlight. The compact size of the

PowerBass XAX series ampliﬁer allows greater ﬂexibility in mounting. 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 sub-

ject 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. 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 6Vrms.

2. 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.

3. SUB SONIC Control

This control is continuously adjustable from 10Hz - 50Hz at 12dB per octave to provide an extra level of

speaker protection from bass robbing power at unheard frequencies.

4. PHASE Switch

This switchable control can be used to correct any “phase” or “time delay” effect in the system by bringing the

low frequency from the rear of the vehicle to the front.

5. BRIDGED CONNECTION Port

For linking two of the same model PowerBass Autosound Class D amps together. Connect the INPUT of the

MASTER to a suitable source via a standard telephone wire with RJ45 modular connectors to the jack on the

SLAVE ampliﬁer. Then select the MASTER/SLAVE switch properly (see Speaker Output Conﬁguration diagram).

6. BASS FREQ Control

This control is variable from 40Hz to 100Hz and allows you to choose the exact frequency you want to boost

using the BASS EQ feature.

7. 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.

8. SLAVE / MASTER Switch

Two like ampliﬁers can be connected together and bridged into a single 2-ohm (min) load. The level and fre-

quency controls on the SLAVE amp will be disabled. Only the ampliﬁer you select as the MASTER will control

these functions. The Dual Link Power Doubling Circuit increases the output power as follows:

XAX 500D x 2 = 1,000 watts RMS (2 ohms min)

NOTE: If using only one ampliﬁer this switch should remain in the MASTER position.

9. LPF (Low Pass Filter) Control

This ﬁlter allows low pass of frequency and is adjustable from 25Hz through 250Hz to eliminate unwanted

high frequencies.

10. REMOTE Gain (RJ45 Jack)

This is the connector port for the Remote Gain Control. Now the ampliﬁers secondary gain circuit can be

adjusted from the driver’s seat.

11. POWER Indicator

The clear L.E.D. lights BLUE when the power is on.

12. STATUS Indicator

This L.E.D. glows RED when the built-in protection circuitry is activated. This indicates a problem with the

system in relation to the ampliﬁer (see Troubleshooting Tips).

13. SPEAKER Output Terminals

As shown in the wiring diagrams, be sure to observe speaker polarity through the system and speaker imped-

ance. This specially tooled terminal is designed to accommodate up to 10 gauge speaker wire.

14. FUSES

For convenience all PowerBass Xtreme mini ampliﬁers utilize common automotive ATC type fuses. For con-

tinued protection in the event that a fuse blows, replace the fuse only with the same value. CAUTION: These

power fuses on the ampliﬁer chassis are for protecting the amp against overdrive. To protect the vehicles

electrical system, an additional fuse should be used within 18-inches of the battery on the 12V+ cable.

15. BATT+ (Power Input Connection)

This solderless terminal is the main power input for the ampliﬁer and must be connected directly to the positive

(+) terminal of the car battery. This terminal accepts up to 2 gauge wire. (see Power Cable Selection Chart for

recommended wire gauge for each model).

16. REMOTE (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 electric 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.

17. GND (Ground Input Connection)

A good quality ground is required for your PowerBass Xtreme D Class ampliﬁer to operate at peak perfor-

mance. 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.

This ampliﬁer is designed to work within a 10 to 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.

*** WARNING ***

Disconnect the negative (-) battery terminal before you start any wiring work! The bat-

tery of your car audio system must be disconnected until the entire wiring installation is

completed.

Your PowerBass Autosound 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 am-

pliﬁer, 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.)
