I started out with this seemingly minor and annoying problem and after a little research on here quickly decided to scrap this idea and replace all four speakers. I researched what speakers would fit my model/yr av on the crutchfield website, just so I'd have an idea what I was looking for. I will say though that I also quickly figured out that just replacing my speakers was not going to work. the new speakers did not give me the same sound as the factory speakers. As they say in for a penny in for a pound. I ended up replacing the head unit as well shich then led to wanting better sound all around which led to wanting some base which led to needing subs and an amp which led to building sub boxes (not as hard as you'd think) which led to wanting to add the backup camea.....In the end though well worth the $$ spent. It was a nice upgrade. Hope this helps. Oh yeah p.s. I went with pioneers all around.
