So when I bought my car it didn't have a radio but somewhere along the line of ownership someone had installed a 480 watt 4-channel Pioneer amp. So last night my friend gave me his factory head unit because he got a new one and we decided to put it in. The car at one point had an aftermarket headunit in it because it had the adapter on that black wire (the one that just plugs in with the male end on it). Anyway I figured that out after my friends tried to just jam the end into the head unit for 10 minutes.
So we get everything plugged in and his head unit still works and everything. Except for one thing, there is no music coming from any of the speakers.
Question is could the speakers all be disconnected or is it amp related? The thing is that I still need to get the RCA plug in for the amp to power the speakers in the first place but could not having that make it so the speakers work at all? I would think that it would still work even without having the RCAs for the amp plugged in. Also what else do I need to wire in to make the amp work besides the RCAs and the amp to the battery and the ground?
Anyway any ideas?
