There's plenty of upgraded speakers for it, check out Crutchfield and they have many speakers that will be a remove & replace procedure. Replacing speakers with direct replacements isn't hard at all. I agree, the factory speakers aren't all that great and new better aftermarket speakers will make a huge difference in sound. Find Car Audio/Video Gear that Fits Your Vehicle at Crutchfield!
