What I am going to do is build boxes for my 6x9s so that i can fit them into the rear deck area where the old speakers would have gone, does any one have any advice, suggestions as to how to do this, currently the person who owned it before me decided to putcher the area where the arm rests are for the passengers in the back...so im gonna have to buy thoes panels aswell, just wanted to see if anyone else has had luck with this idea, or and reason NOT to do this....
