It's been a while since I posted here, although I have been lurking around for a long time. I just recently picked up a 2007 sport with the standard audio system. First thing I noticed is that the lower speakers in the doors are either blown or unplugged, Is there any suggestions from anyone here as to what to replace them with? I will be replacing the upper speakers in the door as well and putting a small amp on them all. Next I want to put a couple of 8" subs in the cubbies behind the seats. I've heard of people doing a setup like this, but have not been able to find any pictures or information about the setup, after extensive searching. If someone could please point me in the right direction I would greatly appreciate it.
