Do you have 4 ohm subs or 8 ohm subs? If you have 4 ohms subs you would wire them in Parallel and get a 2 ohm load, a kicker zx 500.1 would work perfect for this. If you have 8 ohm subs you would again wire them in parallel and get a 4 ohm load and you would bridge the amp on a kicker zx 550.2 and this also would work perfect.
