What a small world man. I met you at the show yesterday. I'm the one with the black Yukon w/ the all Rockford Fosgate setup (three 12s & a pair of T1Ks). If only I had known you had a set of BTLs. Thats something I'd like to hear in person. Actually I just ordered a pair of BL 18s this morning to replace my 12s. Just an FYI, I have a TermLab meter so if you come out to anymore shows I'll be glad to let you do some testing & tuning.
