Alright, I had a crappy dual headunit that came in my car...I had to rewire EVERYTHING...There was already wires ran for a system..but they where cut up at places. so I just reran it. and put all new stuff in. Now My moms bfs brother told me some BS that the dual head unit isnt working or something with the amp cause the internals are all messed up. I believe him cause hes a hardcore nerd...So we take the old head unit that came in my brothers car..(REAL old sony xplod. Top of the line in like 90's haha.) Rewire Everything..and All that works is the sub..no speakers...

Anyone have any like PICTURES of their wiring for the head unit?

or should I just put all my speakers on my amp?

 

Did you wire the speakers into the system? Also is the stock harness cut or is it a plug and play harness?
