[QUOTE="mastershake575, post: 8780408, member: 665251"] In his case yes you would, to say otherwise would be defying physics. The DD1500a would greatly exceed his maxium power draw of his stock alt even with 100% efficiency and even with his car requiring zero amps to run (neither of those scenarios are even close to true and it would still greatly exceed it). I've tested a 750watt korean board (Q1-750) on 5 different 4 cyclinder cars (ranging from 80a all the way to 130A) and every single one of them was handicapped signficantly (the 2 cars that did eventually get an aftermarket alternator saw dramatically increased output running same amp same sub combo). Electrical isn't something you can fake, there's a difference between "oh yeah I think it's running good" and "oh wow this is what the amp is suppose to sound like". In his case it actually be better to wire down for better efficiency and less heat [/QUOTE]
