Im new to this thread, but anyways just today i had a sub and amp laying around and decided to put them in my 95 4runner. Ive installed a lot of systems and all to this day work fine but when i did it in my 4runner my rear speakers stopped working. Little did i know that because its a "Limited" their was a built in amp from factory. But i had replace the head unit years ago and all speakers worked fine. There are 6 speakers in the back and 2 in the front from factory. Anyways how can i make the rear speakers work with the sub? Thanks. I know its kinda confusing but i tried my best to explain my situation.
