MECHMAN Posted April 17, 2012 Report Share Posted April 17, 2012 You need to do the REAL big 3. Add 1/0 cables directly from your alternator to your primary battery for both charge and ground. Don't ground the alternator to the chassis or engine, ground it to the battery. Ground your battery to the chassis with 1/0 cable. Your alternator is not producing enough power to maintain battery voltage, your vehicle will need 40-80a to maintain operation, not leaving much for audio power. I would recommend a high output alternator, around 200a, and an additional battery. Quote 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
