Okay, giving me an easier way to hook up the amp... I get that part. Now, don't go nuts here, but... what is a sub-woofer and why would I want one?
I have replaced head units before, but I have never replaced anything else. This whole 'sound system upgrade' thing is kind of confusing. I just want a better system with cleaner, crisper sound and loud enough to hear with the top down.
