hi Guys, I havent posted here in a while, but i am in need of some guidance. I just ordered 3 hifonics BX1606d's or whatever the numbers are.... Now i have to order some subs, I can't decide between Q's and BL's. I have no idea what all the options are for on the bl's and if someone could explain all of them that would be awesome. I was planning on putting 1 of the hifonics on each, and i also need some advice on box size, tuning etc. SQ is not really a concern of mine, and i have made all the electrical upgrades to the car so everything will work with the power. The Truck is a 2001 GMC Sierra EXT cab, similar to the red one with the 4 15" SSD's in it. My other question is: I do not have a paypal account, is there any way i can do the transaction with FI without going through paypal? Thanks in advance. by the way my name is supposed to be SLAYERIZEd, im just a huge retard.
