A good place to look for aftermarket replacement speakers is Crutchfield. You can at least figure out speaker sizes/prices, etc. even if you don't buy them from them. www.crutchfield.com

 

Yeah, they have been around for quite a while and I think they carry top of the line products. Good recommendation.
