[QUOTE="Art Welter, post: 97264, member: 52"] Re: Are my amps underpowered? Although as others have pointed out your problem is likely a polarity swap somewhere (speakers can be wired wrong from the factory, check with a 9 volt battery that they both "pop" in the same direction), it should be pointed out that at 12.6 volts, even if the amps are 100% efficient, the peak draw is 175 amps, 10 times what it would be with household 120 volt power. A single car battery won't provide that amount of amperage for long unless the alternator also can keep up to the demand. [/QUOTE]
