That is very detailed thankyou for taking the time to reply. Oh how I wish I could hear a BSW upgrade before buying one...it seems the easiest and safest sine I have warranty however I have never given 8' subs that much credit always thought you need at least a ten.

I listen to a lot of hip hop so I like base. IMO I think the stock setup is about a 6 out of ten with a ten being a mirror rattling bass...I just want like a 8 out of ten.

Anyone in Canada.....calgary have stereo upgrades on there X5s?
