I have a 95 civic EX and i want to upgrade the speakers and such. I want a really nice sound and some good bass to it. Dont get me wrong, im not some tool trying to have hella loud bass and dubstep. I just want something nice. I really dont want to spend more then $400-500. I really dont know what kind of things to look for but the radio i have is "Kenwood KDC-352U" if it matters. thanks for any help!
