So, I need new speakers for my car because one of the rear ones went out so I'm doing the whole setup. I have 6 1/2" round speakers all around in my car (2001 Nissan Altima), but the rear speakers don't even have grill holes cut into the rear deck and they just sit underneath it. Do you guys think it would be possible if I could maybe get some 6x9" speakers since if I got new ones anyway I would have to cut out holes for them anyway? I'm willing to spend up to 300 bucks on the whole setup and I was also thinking about getting a new head unit (maybe something with a remote) but I want to start on the speakers first. So, any suggestions?
