I just installed an old Pioneer Super Tuner III tape deck in my dad's accord and everything works awesome when the cars ignition is on the first and 2nd click of the iginition, but when I start the car the head unit stay on but doesn't play, what could be the problem?

 

anyone?

 

do those receivers only have one ground for everything? Like a single black wire forreceiver ground AND ALL four speaker wires?

I'd check all wire connections again.

It's sounds like a bad ground or connections.

 

ya i found the problem the ground came out of the actual circuit inside, just soldered it back on nd everthing works
