JL Audio makes a great Sub & Amp.

Biggest thing is to make sure the Amp's RMS matches the Sub's RMS at the right ohm. Probably 4 ohm.

I have a 300w RMS JL Audio Sub in a corner mounted sub box made of 100% fiberglass. You really don't need more than 300 watts RMS IMO, unless you are a bass head.

The other piece to the puzzle is getting mid-bass subs underneath the seats that play nice with your corner mounted sub
