A cheap and easy x-over would be an F-MOD. They're in-line and plug in between the patch cable and amp. They cost $30/pair from crutchfield. I'd get the 70Hz hi-pass filters for your app.
A single 10" sub can play very loud as long as it's a good quality sub in its recommended enclosure type.
Here's a sample sub/amp setup that would do the trick:
- Kenwood KAC-719 mono bass amp. It seems you like KW, and it'll put out 230w at 2ohms. It's also got a variable low pass x-over to make it easy to tune it into your system. Crutchfield has got it for $160 (cheaper elsewhere if you just look around).
- You can get a single 2ohm 10" sub. Any decent brand should do. You can get a DVC (dual voice coil) sub with 4ohm coils and wire them in parallel to get 2ohms.
- Or, you can get a couple of 4ohm subs and wire them in parallel to the amp. If you decide to go this route, make sure you go with VERY efficient subs. They're only going to be getting a rated 115w to each sub. But, with efficient subs it'll sound good. A pair of 8" or 10" Bazookas would be a good choice here if you prefer their type of sound (punchy, high impact, "loose" bass). You also wouldn't have to worry about buying or building an enclosure for them.
Lots of choices here. You'll have to decide what fits your taste and budget. I would recommend going with as flexible components as possible, tho. That way you can still use them in your systems down the road. Much, much cheaper than buying all new stuff every time you decide to upgrade/reconfigure.
