e-fans are on my list of upgrades..as well as an intake..
and the BTL is fairly heavy..80 lbs for the sub then the weight of 2 sheets of mdf lol..im sure its not helping me at all..i guess i can find out better when i put it back in the truck in a month or so...i have 3.73's as well
If Im not mistaken, JK as plenty of MDF, Dynamat, subs, the works... his setup is pretty fvcking sweet man... i cant remember what thread it was, but it was nice!
