Kris Boss' Denali System...

[B0$$MAN]

but my question is you have to turn it up to 36 on the volume knob to get all the bass?

Depends on what db-level my bass knob is at. When doing bass tests, you don't want the db-level to be so high because of clipping and you don't want your subs bottoming out.

I recently sold this setup since I like to have trunk space to throw stuff in. I am looking at moving to 1 Pioneer Premier SPL 15" 3000W RMS 8000W MAX.
