Power Wiring
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
PowerPlus Amplifiers
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.
Battery Terminal
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):
