I what to replace my rear sub with a aftermarket piece. What woofer will work for me. Still using factory system

 

Hmm... If I remember right those were 8" woofers But the area where it was mounted was shallow. I'm not too sure, I haven't dove into a 2000 before. My suggestion is to pull it out, and check around with a few stores to see if anyone has close to the same dimensions.
