[QUOTE="DidUHearThat?, post: 6728567, member: 594758"] No, it's not a 100% efficency system. It is a gross calculation of potential draw versus potential input. Not even close. My statement is 100% accurate. A 90 watt [sic] alt cannot power a 5kw amp. If you have an abusrd pile of batts (10+), you could power it for a few minutes, but the 90 amp alt cannot provide a reasonable recharge time. 5 hours recharge to get 4 minutes of play time in a daily driver? No, 100% fail system. He needs AAA, because he will be broken down somewhere in the first week. Your system has a much tighter input to output potential, simialr to mine. A decent battery, or two, can make up a small shortfall for limited periods of time, but not at more than 3 times the source power. Ultimately the alt is the ONLY source of power. Noobs need to be told point blank you can't power jiggawatt amps from lawn mower sized electrical systems. Don't waste your money on 5kw amps when you can't power them. If you want to run with the big dogs, look at the electrical systems that they use. If you want to use stock electrical then you need to manage your energy budget intelligently. 5kw class AB amp on 90 watt [sic] stock electrical = fail. [/QUOTE]
