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.

So, slightly new setup recommended by Crutchfield. I feel like the amp is cheap, but it'll put out the required RMS for the sub, 150.

Same sub:

Amp wiring kit, recommended by Mark at Crutchfield:

Speaker wire, for the amp to sub:

So this seems to be the bottom line for me to put everything in the hatch, 280. Not a bad price at all.
