Well, with my experience in the past, capacitors do not do well with Class D amps, which I have one of for the subs. This amp is supposed to be extremely efficient--somewhere around 83%. In any event, if I am pulling 1,100 watts constant power, what size wire do you think I should install from the battery? I know 0 or 2 AWG seems like a lot, but remember the longer the wire, the harder it is to draw power from, thus creating a bottleneck effect in terms of how much power the amps will be able to draw from the battery.generator said:Number "0" wire? Hold on...Zero guage wire can handle 800-1200 amps of current @ 36 volts. You aint gonna be anywhere near 300 amps at 12volts. If you are pulling down 800 amps I guarantee you are melting a cell in that Nissan battery and the alternator is going next.......I am sure the warranty folks are gonna have a good laugh at that one. Good look though. I like your style. Make sure you put some large capacitors in the power line.
