1. Iinstalled two polk 6 1/2 speakers on the doors and to check the sound quality on each i changed the fade and balance to both doors and noticed that the drivers side door speaker basically sucks, it is very quiet and very scratchy and i installed it the exact same way i did the other side and even tried switching speakers and adapters and the drivers door was still bad how do i fix this?

2. I got polk6x9 speakers for the back and iwas wondering the easiest way to open the back to get to them?

 

If you switched the front speakers around, and the drivers side still sounds like crap.I'd have to say it's probably the deck, or wiring bad on that side.

The rear speakers come out easy from inside the trunk.

 

Yeh so i put the back speakers in and its the whole left side wacking out, both front and back. So if its the deck or bad wiring on the left side then where would i look and what do i need to fix it?

PS: I really want to fix this because the right side sounds great and i think it would be what i've been looking for if i fix the left side.
