Question about Clarion APA4320 Car Audio Amplifier
I've checked the fuses. They're fine. I took amp out and put another amp in its place in my car and the other amp works. Something is wrong with my APA4320 Amp. It looks brand new, not a blemish on it. Its never been dropped, nor received any moisture. I need help. Is there something inside this AMP that is possibly blown? The lights power on showing that the amp turns on, but there is no sound. Again, I've replaced the amp to make sure it wasn't my power wires, speaker wires, or RCA wires. With the temporary replacement amp, I can listen to music. I just don't want to use this "other" amp as its really outdated.
I agree that It could be one of the other reasons listed here.....
But, I had the same problem with a 1,000 watt Kenwood amplifier and it worked like a boss for the whole two years that I had it and then one day the box that I had my subs in somehow came apart and after I changed out boxes the amp quit working. It came on but it wouldn't work anymore except for when I turned it a certain way or sat it against something.. Anyway it ended up being a loose female port plug on the inside where the auxilary cables plug up.
Hope it helps.

SOURCE: Protection light and nothing. ??
How about the speaker itself? This problem can be caused by a blown or defective speaker. If you disconnect the speaker wires from the amp, do you still get the protect light?

There is not enough power coming from you radio to power the amp. You might want to look in to a capacitor. What this will do is it will pull in the power and maintain a steady output for your amp to operate

SOURCE: Amp doesn't come on
You did not say whether or not you checked the wiring going to your subs. Many times, a shorted or grounded speaker wire will cause an amp to fail. And if the amp powers up OK with the subs disconnected, I'd suspect one or more of the wires.
Hope this helps.
