Charging System

In some cases, the installation of just one (1) amplifier could be enough to 
overload your factory electrical system (i.e., alternator). Depending on the 
state of your electrical system and overall condition of your vehicle, you may 
need to upgrade your alternator and battery. After the vehicle is started, the 
alternator provides the power to your electrical system, not the battery. When 
the engine is running, the alternator is your main source of power. Upgrading 
the alternator should be your first consideration if you should experience a 
voltage drop in the system when operating your audio system. Adding 
capacitors and/or batteries without upgrading the alternator will only make the 
problem worse because these devices put an extra load on the alternator. After 
upgrading the alternator, capacitors and/or batteries can be installed if desired. 

Use the following recommended wire gauge as a guide when installing your 
amplifier(s): 

Power Terminal (+12V/B+)

Connect the main power wire to the battery, within 18 inches from the positive 
(+) battery post, using an adequate size fuse or circuit breaker capable of 
handling the current of the selected power wire. A fuse or circuit breaker must 
be installed to prevent a possible electrical fire should the main power wire 
short to ground.

Remote Terminal (REM)

Connect the power antenna or amplifier turn-on lead from the receiver to the 
amplifier remote terminal.
