OK heres my problem, i have an 05 equinox and i got 2 L7's powered by a zx2500.1 only thing is that all my interiors are still stock and they are all 6.5". i want to get them replaced. can someone please recommend me a good set of interiors for both the rear and the front and also an amp to power them. i am not looking for anything too pricey at all
