I got my new HU and hooked up the harness. My HU powers up and my antenna works but nothing comes out of the speakers. There were two wires on my stock radio and the harness I bought had a connector for only one of them. Is this a problem?

 

no the replacement harness only plugs into the large stock plug, the other isn't connected

 

yeah, i kinda figured the other one wasnt used but like i was saying. everything works and the headunit powers up but i get no sound. any ideas?

 

What type of HU? I had to wire both ground wires on the harness to the one Black ground on my HU in order to get it to work, and you double checked that all your speaker wires are connected correctly....tough call when its not right here in front of me but if your HU is powered up and the speakers are all connected properly the only other thing is that the HU outputs are shot, or something isn't setup on the HU
