Why do I need to upgrade my charging system?


    The stock alternator and battery meet the electrical needs of your car’s stock features, and that’s about it.

    The draw from a big* audio amplifier – combined with regular vehicle features – runs your battery down faster than the alternator can charge it. This causes the voltage to drop.

    Voltage drops damage amps.

    Your car needs enough power for stock features, AND your big new amp. To get the extra current you have to upgrade the alternator, add a AGM or lithium battery, and beef up wiring under the hood.

    *A “big” amp is anything over 1000 W RMS. Smaller amps are often able to run on a stock electrical system, but upgraded charging never hurts!
