I recently installed an aftermarket radio into my 2004 Toyota solara sle, the radio works and plays music when the key is turned to ACC ( accessory mode) , but as soon as I start my car the radio stops and no sound comes from my speakers. The radio stays on and says it’s playing music, but no sound is coming out. Does anyone have any suggestions on why this might be ?

Interesting issue.  Normally, we would consider if the factory system included a factory amplifier that is now miswired.  

Did you purchase a vehicle harness so the factory wiring was not cut, or did you cut the factory harness off and make manual connections?

I made my own manual connections with a wiring harness . There’s a built in jbl amplifier, I may have wired something backwards

It is possible that the power to the JBL amplifier is somehow not provided when the car is running but is in ACC.  You will want to measure voltage on the turn-on wire to the factory amp as well as amp power.
