i have come to the conclusion that owning a single cab truck is the worst decision you can make when it comes to installing a ******* system. i have a 99 ram single cab, and im stuck, i want more, but ever store tells me im maxed out, thats depressing for a kid like me thats getting hooked into car audio. i have a custom ported box built to specs for 2 12 jl audio w3s. it bumps pretty decently, miked at 145.5 hahahah thats on some old a$$ mike, i imagine its low 140s, upper 130s, nothing special but not bad for my first set up. but i want more, baddly. i was trying to fingue out a way to fit a single w7 in my truck if possible, but thats highly doubtful. i just want to go to one sub that will out-preform the 2 w3s, and that i will have enough room to fit the sub in a ported box. i guess you could say i am going for a non-professional sq system. please help me out.
