which amp is best for my situation (need help fast)

[*TheVirus*]

ive decided on the lanzar opti series, cuz i can get them off ebay for pretty cheap. the sub im gonna have is a resonant engineering HC 15, with dual 2 ohm coils. i want either the opti 500.2, the 1000.1D, or the SL Opti 800.D. i only have a stock electric system, so would these amps run fine off that? which one would be best for me? oh, and are these underrated? thanks for any info. -Daniel

ALSO HOW HARD WOULD THESE AMPS be on a stock electrical system (alternator is about 75 amps)

it would depend on the car, but i have seen many people run those amps on stock electrical system. hell..i'm planning to get those amps for my car and plan to do no electrical upgrade at all. and yes..those amps are underrated, providing that you give it more voltage than the one they rated the amp at.

what kinda car you got, and how many amps is the alternator?

[GSteg]

car? what car? i actually run all my stuff in my mom's Ford Aerostar van. i think it has like 90amp alternator. i'm not sure.

also, upgrade the 3 main wire under the hood and get a capacitor. save up a little more money and get like an alternator rewind. another solution is getting an optima deep cycle for your car. it recharges fast so u get less strain on the alternator.
