Question about Clarion APX480M Car Audio Amplifier
My Clarion APX480M amp will power on(the green LED is lit up on the amp) and sound comes out of the speakers, but the music is very hollow sounding. The subwoofer amp is also making a hissing/scratchy sound that you can hear when you hold your ear up to it. I have two of these amps in my boat so I am not sure if the problem is the stereo or amp(s). I have one driving 4 7" clarion speakers and the other is driving 2 subwoofers. Either way, I went from sounding cool on the water to not being heard at all.....:):) Any help is greatly appreciated. Thanks, Jason
This sounds like a signal problem. Make sure that all of your signal cables are plugged in fully. If all are, you need to check for coninuity between the shield ground of the head unit's RCA jacks and the case of the head unit. With no RCAs plugged into the head unit, you should read ~0 ohms between the shield of the RCA jacks and the case of the head unit.
