I'm eye'n just one Fi Q12 in a sealed box w/ ppi d2000/1 on top of a 5 farad cap. Back seats are 60/40 split, so I'm taking out the smaller seat and mounting everything there. Vehicle is a quad cab 2003 Dakota. I had a system in a trunk before but not something like this. I know it's going to be louder because of the whole cab thing, but what am I really getting into here? Am I going to be disappointed only pushing 1175 watts to a single sub? Can this sub handle a bigger amp, and if so, how much bigger? I wanted to go SQ since I listen to a little of everything, mainly rap though. Questions? Feedback? I wanna build this system right the first time. Oh, btw, am gutting the whole interior and dynamatting everything.
