The radio lights up all displays light up CD changer is working and shows to be playing. It's seemes to be working but NO SOUND. HELP The serial # is PI 043875 Pioneer....Toyota # is 86280-30200. Thank you Jerry
The speekers are hooked up
I want to keep it stock.

why dont you just get a aftermarket one it'll be the easiest thing to do any 400 watt or 300watts amp would do fine for some stock speakers if you dont want to change the speakers good luck

Have you checked the speaker wire connections?
