Sounds like you might have blown the amplifier in the deck. Hook the RCA outputs into an external amplifier of some sort and see if there is sound there. Also, I second markus on check all the wires. Plus this time before you put it back in be sure to cover all non used wires with tape or something to prevent shorting. The amplifier turn on wire shorting for example has been the cause of many blown decks.
