these subs are much more powerful then what i can supply. the amplifier doesn't even blow 2 20 amp fuses with the gain at max (so 560 watts) these subs are rated for 400 watts each. im running these at 1 ohm and i highly recommend rockville. the amplifier is on 8 gauge with a 50 amp fuse. each sub has a 20 amp fuse because when i first had the car it originally had a 50 amp alternator (its now 72 amp).
