Yea i should have put down some info, i was just wondering about good 1000w RMS 1 ohm amps. Ok here goes, car is a 2000 Hyundai Accent. The electrical is pretty weak. 80amp alternator. 650 ca batt 500 cca. no big 3. When i said highs are not that loud i was reffering to bass highs, all speakers are stock so i dont expect much there lol. Ok for wiring i use RF 8awg for power and 12awg for sub. 80 amp fuse from battery. Amp is RF P5002 740w dynamic. doubt anything past 680w can get to the sub. Wired bridged @ 4ohm. I was actually looking at US amps, not sure how good those are. And thanks for all your help.
