I've been searching forums and audio websites and just can't put it all together. I want a sub or subs for my crew cab. I Don't know much about car audio so I'm clueless as to what will work for me. I just installed a pioneer touch screen stereo and already had aftermarket speakers. My stereo is already set up to run a sub. I'm not a music fanatic, I just want a little punch. I'd like something already put together if possible but open to suggestions. Under or behind the rear seat is what I have in mind.
