I have the Pioneer setup in my Cruze. I want just a little more out of it. Looking for more low and high bass fill. My thought is replace my 6x9 with something like the JBL P963, Pioneer or even Morel nothing too pricey. I have had sets and like the frequency range they produce. Another idea is to swap in a 6.5 sub but wont have an enclosure for them just the deck. Thoughts or experience with the Cruze. I know best bet is to put a seperate dedicated sub just dont want to that route at this time.
