Power / Ground cable size

It is critical to use the proper power and ground cable. Select the size listed here for your

amplier model. Always use high

quality copper cable.

Cable size recommendations for multi amp systems are available on our website.

Properly route power,

speaker and RCA cables

through the vehicle.

Choose a mounting location that will provide adequate air

ventilation. Mount the amplier to

a secure surface. Do not mount

the amplier upside down.

Using spade terminals, connect the +12V to the power cable from the battery, the REM to the source unit turn-on wire and the GND to the chassis ground..

Strip each cable back approx 1/2”, connect the +12V to the power cable from the battery, the REM to the source unit turn-on wire and the GND to the chassis ground..

Bare metal

Connect the RCA cables to

the INPUT connectors. The OUTPUT can be used to provide input for a second

amplier.

The HI INPUT is for use with source units that do not offer

RCA outputs. Use the supplied

harness to connect to the source unit’s speaker output.

Connect the power cable to the positive battery terminal. The power cable must be fused within 18 inches of the battery terminal.

Re-connect the negative battery terminal making sure it is securely tightened.

Using spade terminals,connect the speaker cables to the speaker output connectors. Follow the

diagram below that best ts your speaker conguration.

The chassis ground connection is critical to the performance

of the amplier. Choose a

location that is close to the

amplier. Completely scrape

away the paint and use a nut and bolt if possible.

DO NOT USE AN EXISTING FACTORY BOLT!

CAUTION

Many new and factory radios require a reset code when

disconnected from battery power. This is an anti-theft

feature. Before unplugging power, you must determine if

your radio/source unit requires a reset code. Check the operation manual for your vehicle or contact the dealer.

Quick Start

Installation Guide

The input MODE switch will “sum” or combine the right and left channel signals in the MONO position to improve bass performance. Select MONO only when the amp is being used for subwoofers.

The XOVER Mode switch sets the type of crossover that will be active. 4 channel models will have two switches, one for each set of channels.

The HPF(high pass lter) control will limit the

output below the selected frequency. This is typically used to protect midrange and hi frequency speakers from damage and to allow a smooth transition from a subwoofer.

The LPF(low pass lter) control will limit

output above the selected frequency. This is used to allow a smooth transition to the higher frequency speakers.

1. If possible, with the source unit off, conrm that the primary volume control is

turned down (counter clockwise).

2. Turn on the source unit (CD, or MP3 player). Re-conrm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or “0” adjustment. Make sure that the green LED on

the end of the amplier is illuminated.

3. Play a clean musical selection of which you are very familiar. CD is preferred. Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.

4. Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion.

5. Increase the amplier level (clockwise) until distortion is heard, then back

the level down (counter clockwise) until the distortion is eliminated. Small adjustments may need to be made to balance the levels of multiple ampliers.

The BASS BOOST or BASS EQ control

will increase the output at 45Hz for more pronounced bass. Exercise caution. Increase the level in small amounts until distortion is noticed, then back off a little.

Some models include a bass

remote. Avoid adjusting the bass

remote while operating vehicle.

This is a critical step to insure your amplier

is properly adjusted to match the signal output level of your source unit.
