you should talk to the guys at the shows. if they are loud. they have to have some idea how to get to that point. unless a shop did it for them. meh I been with my girl for a long while now. but I still love to make as much time as I can with her. Dont let it get addicting.ahhaha.I have been to car audio shows amuture ones and i can say i dont get close to those guys but i been in to car audio for some time its just i dont think im geting any better underthe hood.I allways wanted to do the big 3 dual alts and like 4 batts + set up thats like all i think about im like sick in the head about this stuf the love i have cuzed me to lose my girl friend pretty much she said that i care about my car audio then her. Well there goes 5 years ahhahahah
