Trying to build up my system and right now I'm working with a pair of CDT CL-61s up front run directly off an Eclipse 3424 HU. But I definitely need some additional bass.

What's the best, cheapest, way of doing this. I'm not looking to win any competitions and I don't want to rattle the windows of the houses down the street. I just want some good quality, CLEAN bass to supplement the awesome CDT comps up front.

I've heard good things about the Bazooka EL8A-HP amplified sub and it seems relatively cheap. Like I said, I really like the SQ of the basic system right now, but I would like to add some bass to round out the sound without going crazy with $300 amps and custom sub enclosures.
