[QUOTE="headless, post: 1747776, member: 566363"] You need a volt meter/DVM/clamp meter to see what is really going on here. Rev the engine while under that load, and while the system is playing and the engine is revved, test your voltage at the alternator where it runs to the battery. If the alternator's voltage is still high (13+v), you have a connection problem between the front electrical system and your amp (cap). If the alternator is reading 10v like your amp's cap does, then your alternator is not putting out it's rated voltage at the load you're providing it, even when revved. If that's the case, check your amp draw from your batt to amp and see if it's To see if the alternator is seeing additional load above and beyond your audio system, check current draw from alternator to the battery; if current draw is excessively higher between that connection than the battamp, you know there is additional resistance either inside the batt or connected to the batt that isn't your stereo [/QUOTE]
