FULL RANGE CLASS D MINI AMPLIFIERS

The PowerBass XL 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 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.

require the on-board computer to be reset at the dealership. Check with your local dealer if you

are uncertain.

To keep your PowerBass Xtreme ampliﬁer running at top performance, choosing the proper location is of

utmost importance. Both Thermal and Overload protection are built in.

In the event of overheating, the ampliﬁer will turn off and only restart when cooled. For this reason the

ampliﬁer should be mounted in a location which will allow air to circulate freely. The compact size of the

PowerBass XL Series ampliﬁer allows greater ﬂexibility in mounting.

MOUNTING THE AMPLIFIER

MOUNTING LOCATION

The XL Series ampliﬁers are IPX67 rated and feature a conformal coating applied to the PC board. This coating

makes them resistant to water, dust, and quick submersion. 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, on the back of the rear seat or

a storage compartment will air can circulate. 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 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 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.

XL-805DMX CONTROL PANEL LAYOUT

NOTE: Panel Layout and Controls may differ by model.

1. Low Level Inputs/Outputs (from left to right)

A. LOW LEVEL RCA Inputs

Low Level RCA 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 10Vrms.

B. 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

devices headphone (3.5mm) output.

C. REMOTE LEVEL INPUT Connector

This is the connector port for the Remote Level Controller. Now the ampliﬁers secondary gain circuit can be ad-

justed from the drivers seat. Please note this is active in all settings HP, LP, FULL.

2. 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).

Fig.2 1-Channel Panel Layout

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 250mV

to 10 volts.

4. SUBSONIC Filter

The subsonic control will ﬁlter out all frequencies below where the control is set and prevent those frequencies from going to

your subwoofer(s). This will prevent your subs from playing any low frequencies that may harm the speaker.

5. LPF

This control is continuously adjustable from 50Hz to 250Hz at 12dB per octave

6. 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.

7. SPEAKER OUTPUT

Be sure to observe the correct speaker polarity and follow the speaker wiring diagrams found elsewhere in this owners

manual.

White Wire = [ +]

White/Black = [ -]

8. POWER AND GROUND INPUT Wires (from left to right)

A. Red Wire BATT+ (Power Input Connection)

B. Blue Wire REM (Remote Turn-On Connection)

C. Black Wire GND (Ground Input Connection)

A. BATT+ (Power Input Connection)

This wire is the main power input for the ampliﬁer and must be connected directly to the positive (+) terminal of

the car battery.

B. REM (Remote Input Connection)

This wire 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 this lead is not at the source unit,

then a switched +12V supply must be used, like the ACC, +12V.

C. 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 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.

NOTE: If installing in a boat, UTV or motorcycle make sure your ground wire is connected to the nega-

tive ( - ) terminal of the battery.

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-805DMX 80A

• 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 etc.),

wiring harnesses, fuel pumps etc.

These ampliﬁers are 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. The XL ampliﬁer is capable of accepting up to 8 gauge power and ground cable. 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.
