I want to put a sub in my z roadster but i dont know where to put it. I was thinking of taking the stock bose sub out and replacing it with a alpine type x or something, but im not sure if that would work or if it would sound good. anybody got any ideas? Also, if i wanted to put in a new sub would i have to replace the speakers? Right now i have an alpine deck and screen hooked up to my stock speakers and sub and my installer used some sort of new metra wiring harness for the Z to hook up the deck to the stock system. So any ideas on what to do?
