 4-5. +12V, REMOTE & GROUND CONNECTION

Ground

BATTERY

Remote Turn on

+12V SOURCE

+12V Power

Connect the +12V terminal of the amplifier to the + terminal of the battery using the same diameter as 

the ground cable, making sure you install in-line fuse holder, approximately 300 or 400 mm. 

From the  + terminal of battery, making sure that there is no fuse in the battery holder

All audio pipe amplifiers should use external fuses and fuse holder. 

Connect one end of fuse holder to the power cable going into the amplifier and the other end of fuse 

holder to the positive battery.

This fuse location will protect the system and the vehicle against the possibility of a short circuit in the power

cable. Be sure to use fuses and fuse holder adequate for the application. 

GROUND

Disconnect the battery and connect 

the GND (ground) terminal to the cars chassis. 

Keep this cable as short as possible 

(not  longer than 20 inches ). 

Making sure that the connection with 

the chassis is rust free and clear of paint 

or grime.

REMOTE

Run a remote turn on cable ( at least 18ga )

from the sw12V source.

This may be a toggle switch, a relay, source 

unit’s remote trigger cables, or power antenna

trigger cable.

Connect the remote turn on cable to The REM

( remote ) terminal.

REMOTE PORT

This port is for remote level control.

Plug remote control’s connector for 

remote level control’s use.

Remote controls level from 

the driver’s seat.

BASS BOOST ( 0 ~ 18dB )

The bass boost boosts frequency 

centered at 45Hz.

LOW PASS FILTER 

Controls the low pass filter frequency 

for the speaker output.

The Low pass filter is always on with

12dB per octave slope.

CH3/4 has range from 100Hz to 4KHz

CH5 has range from 50Hz to 150Hz.
