USE THE PROCESS OF ELIMINATION. SWITCH THE RCA INPUTS AROUND AND IF THE PROBLEM STAYS IN THE SAME CHANNEL, THE THE AMPLFIER OR SPEAKER IS AT FAULT. IF THE PROBLEM SWITCHES TO THE OTHER SPEAKER, THEN THE PROBLEM IS THE RCA CABLE OR RADIO ITSELF. YOU CAN VERIFY YOUR FINDINGS BY STARTING WITH THE SPEAKERS FIRST. SWAP THE SPEAKERS AROUND AND IF THE PROBLEM STAYS ON THE SAME SPEAKER, THEN THE SPEAKER IS AT FAULT. IF THE PROBLEMS SWITCHES TO THE OTHER SPEAKER, THEN THE AMPLIFIER OR INPUTS ARE TO BLAME. BY FOLLOWING THESE TWO METHODS, YOU WILL BE ABLE TO DETERMINE EXACTLY WHICH COMPONENTS ARE AT FAULT. REMEMBER, YOU HAVE AN INPUT, AN AMPLIFIER AND A SPEAKER. THIS PROCESS OF ELIMINATION WILL HELP YOU IN THE FUTURE WITH MANY TYPES OF PROBLEMS. LET ME KNOW IF YOU REQUIRE FURTHER ASSISTANCE.....V
PS: MAKE SURE THAT THE GAINS AND BOOST CONTROLS ARE SET TO THE SAME LEVEL FOR BOTH CHANNELS BEING TESTED. ALSO MAKE SURE THAT THE BALANCE CONTROL ON THE RADIO IS STILL SET TO THE MIDDLE. DON'T WANT THESE CURVEBALLS INTERFERING WITH YOUR TROUBLESHOOTING......V

Do you have a multimeter? If so, measure the DC voltage across the speaker terminals for the channel that's not working. Is the voltage well under 1v? Have you tried moving the RCA signal cable from a working channel to the dead channel? Have you tried moving all of the switches and controls to see if the dead channel goes in/out? Have you tried a different speaker on that channel (swap wires at the terminal block)?
