[QUOTE="hispls, post: 8716239, member: 614752"] I'd upgrade ground from battery terminal to frame on a new car even if I weren't adding audio. The factory ground is usually inadequate even for the stock accessories. Beyond that I do not believe the other ones are necessary where you're sitting. As far as where your battery is happy it's largely dependent on your listening habits but those JL slash amps will definitely make rated power and aren't the most efficient stuff around. Of course they're also built rock solid and I believe have regulated power supply so they're not the sort of thing that'll break from low voltage, they may not even drop output with low voltage provided you're high enough to keep them powered up. That said, if you're running it really hard you can expect premature failure of your stock bat and alternator but those are cheap and easy enough to replace. Personally I'd try to get away with just stock electrical (with upgraded ground anyway) at 1500W and if that didn't hang just get one of the premium parts store or duracell AGMs. Pre-lithium I was using Bosch branded premium AGM we bought from Pep Boys which had 5 year warranty. Parts store battery warranties are easy to claim since the kid at the counter really doesn't care what you did to it. If it load tests bad and the date is < the warranty period the kid behind the counter hands you a new one and you're good to go. You've got to get out to some shows up here in the Northeast at some point. Keep an eye on NADBL website. We'll probably have another one in Sanford Maine this year and there may be one in Nashua at some point. [/QUOTE]
