Car Audio Amplifier PRE Installation Guide

BySAWH'S

Recommended gauge wire for the different size of fuse that each amplifier carries.

Required / recommended power, ground wire and proper external fuse as seen below: 

An amplifier that uses a 40 AMP fuse could use 6 Gauge wire. 

An amplifier that uses a 60 AMP fuse could use 4 Gauge wire. 

An amplifier that uses a 80 AMP fuse could use 4 Gauge wire. 

An amplifier that uses a 100 AMP fuse could use 2 to 4 Gauge wire. 

An amplifier that uses a 120 AMP fuse could use 0 to 2 Gauge wire. 

An amplifier that uses a 200 AMP fuse could use 0 to 2 Gauge wire. 

 

The fuse should be installed away 0.2m from the battery. The ground wire should be connected directly with the chassis of your vehicle which should be metal to metal ground point connection. The amplifier must be mounted securely at a solid, dry and low vibration surface in the trunk or passenger area. Fix the amplifier in an open air area to insure proper heat dissipation. Fix the amplifier in a place where can access easily to set the input controllers. Install all amplifier cables as far as possible from car electrical cables such as the car ignition cable. 

 

IMPORTANT:

  • When bridging two amplifiers together please refer to the bridging wiring chart of the amplifier’s user manual. 
  • When bridging two amplifiers you should use the same model amplifiers. 
  • Please make sure the negative (-) speaker terminal of two amplifiers are connected by the same gauge cables as the positive (+) terminal being used. 
  • DO NOT connect any signal cables with the input RCA jacks when bridged as slave unit. 
  • The LPF, Input level and remote functions will be disabled on slave amplifier when bridged. 
  • All functions of the slave amplifier will be adjusted by the master amplifier.
