Aftermarket radio powers on but no sound when car is started
Hi. I have a 2005 honda accord lx. I installed an bluetooth aftermarket radio. I have all wires matched up and connected only wire left is orange illumination wire.
When the car is on accessory the radio powers on and there is sound but when the car is started the radio powers on but no sound comes out. Any help would be much appreciated.

Possible you have connected a mute wire to an ignition voltage source. An aftermarket radio just needs 12V on the red and yellow wire for power, and just one ground on the black wire. With those three connections, it will turn on and produce sound as long as the output isn't shorted.
An aftermarket radio will also mute the speaker output if it senses a short circuit. It is possible that you could have a short that is somehow tied to the vehicle running.
