I just put 2 polk db651's and 2 db6501's in the cabin, so now I need to take care of the low end of the system. I really would like to get some good sounding bass but I only want to spend $400 or $500 on a good sub/amp combo. It sounds like you guys really know your stuff when it comes to audio equipment. I was just curious if anyone had any suggestions or what I should stay away from.

I was looking at this set-up...

Any thoughts would be appreciated... I wish I would have asked for opinions on the sony amp before I bought it for the cabin speakers
