How many amps will 2kwatts draw? 3k? How many amps will 234ah of battery and a stock alt (dunno size..'04 ram 1500 work truck) be able to sustain?
It depends on the efficiency of the amp at the impedence you're wired to and the frequencies are being played through it.How many amps will 2kwatts draw? 3k?
Sustain? Batteries do not help the system "sustain" current draw. Only an alternator can help the system sustain. Batteries merely prolong failure. It has reserve current at 12v and once it is depleted, the battery is no longer useful, and the amp will either shut off or blow from clipping like crazy. So the question you're really asking is, based on my duty cycle will my equipment last if I put a 3000 watt amp on stock electrical? The answer is no, and your amp will not put out anywhere near what it is rated at either. Do it right the first time or you will pay later.How many amps will 234ah of battery and a stock alt (dunno size..'04 ram 1500 work truck) be able to sustain?
