well i kind of tricked ya...but if anyone can help...this board can.

problem is my car audio system...i have 1995 Saab with a Harman Kardon 10 speaker sound system with a 150 watt HK amp...

the bass is waaaay too boomy.
I tried turning down the bass tone adjustment, but its still there.
The bass is supplied by two 6x9s with plenty of space below them. Will some kind of stuffing like foam help reduce it? should the foam be uneven and/or thick?
Any other suggestions?
Great system if I can tame the darn thing.
