Thanks for posting this. When I set my system up, all the possible bass control options just confused me and I ended up leaving everything the way it came from Outlaw. But it just didn't sound right, the bottom end just was not there. Radio stations sounded better in my VW Golf than they did in my living room. After reading this thread... I checked to see if my switch was on BP... took me reading the manual to find a switch with a BP position. Seems the Bass Management switch on my unit was set to 100!! No wonder the bass just didn't sound right. Set the BM switch to BP and everything sounds much better. Thanks
