Rear Speakers Won't Work.
I have a Jensen Power 400 in my trunk and I was wondering if my 1995 Toyota Turcel with 4 speakers can play... ALL 4.
My Rear Speakers do not work while my main speakers do. I have my rear speakers hooked in each with 1 positive and 1 negative I believe... I'm not very knowledgeable about this sort of thing. I just want my rear speakers working too. Thx
