check for a short on the speaker out wires or cut and tape them so they do not ground out

make sure the speaker wires in the car do not have one side grounded.the output on the clarion is a floating output and cannot be grounded.the best solution is to look at the wiring on each of the speakers,and match them out to the ones on the clarion.the most common colr code is white front left,gray front right green rear left and purple rear right.each speaker has a plus and minus.mixing them up will result in the speakers being out of phase and result in poor bass performance.i would wire the wires directly to the clarion using crimp connectors.the first thing i would do is power up the stereo out of the car to 12 volts,and using a speaker make sure you have sound coming out.the yellow wire which is the clock/memory is a must to be connected to constant 12 volts or no sound can result
