A good subwoofer? Options

[SwissFerdi]

I've been wanting a sub ever since I got my speakers, it's just another upgrade.

My speakers:

Head unit:

Now neither are fantastic, but they work excellently for my purposes. In that same trend, I'm not looking for the sub-of-all-subs, just something to fill in the lows. I listen to mostly trance and dance, with some hiphop and rock in between. Basically, I'm looking for a good budget setup, and happened upon this:

Now my question to you fine folks is if this is at all a good sub. I know RF makes quality subs, but would this fit for my use and application? I don't want anything boomy, just crisp, clean, yet deep bass. And best of all...the sub is 2 for 1, which means I can sell the other to make some money back. I would be pairing the following amp to it, which I believe (this is where I need your expertise) will match just because it can do the required watts at 4 ohms.

Thanks guys. I'll also be calling Crutchfield tomorrow, so don't think I'm just ignorantly asking for your help.

Ordering the RF sub and enclosure tonight, and I'm getting the Dual amp from somewhere else. Bought a 680 watt Scosche amplifier wiring kit for $25 at Wal-Mart today, and also 50 feet of 16 gauge speaker wire for 10. The kit includes:
-16.5 ft 8 gauge power wire with fuse holder
-2.5 ft 8 gauge ground wire
-16 ft. twisted audio cable
-remote turn-on wire

So I assume I should be good as far as wiring goes? Thanks for the patience folks, I realize I'm asking a lot of questions.
