Hey guys....come spring, I'd like to add a nice sub to my Box. Not looking for volume - looking for clarity and quality. Ideally something small that will fit behind the seat. I've seen a few recommendations for the Kicker sub/amp all in one. Is that the one to go for or are there other options? Up here in Canada, that's one's about $600 on Crutchfield, so want to make sure it is truely the one.
Also like something simple to install. I've got an upgraded Kenwood touchscreen and some focals in the doors. Want to compliment those.

Thanks!
