Question about Clarion APX401.2 Car Audio Amplifier

1 Answer

Protection light and nothing. ??

So Im running a single 10" for extra punch, have everything all wired up, but i keep getting the protection light. I've tried 3 different amps (1 brand new) and keep getting the same problem. I thought fuse or output problem, so checked the amp and main power fuse, both good. checked the remote and rca wires and their good, ground is also fine. Can anyone help me out to pin-point the problem? I've checked the speaker cables and they seem to be fine aswell, also I checked the cabels inside the box to the speaker and found nothing. Any ideas? Thanks.

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?

check the OHM resistance on your subs. do not go under the minimum OHM value.

remove the power wire and retry again, if it does the same thing the amplifier needs repair.
try:
ampmedics.net
or sell it for parts on ebay

I have a pyle 1000w 2 channel amp.just got it last week. last night driving home, stops working. protection light stays on. when i checked it, it was hot. so im assuming the thermal protection kicked on....
keep it in a vented area dont ever cover it position it were nothing will block it.it sounds like it does not have a fan so they sell those fans that you sit your laptop on.they cost about 10 bucks and wire it to your amp remote and ground inputs and it should help it stay cool....

Protection light flashes on and i get nothing
Hello shwoop22,

It sounds like power is shorting out or the amp is defective. With the fuse removed, use a multimeter set to ohms and check between the power terminal to ground.

The protection light will normally come on if the amp overheats (for example when running with too low impedance), or if the speakers are shorted.

Hope this helps.

Protection light
take the amp out and hookit up to the car battery and let it charge then unplug it do this a couple of times then rehook it to the cars audio system it sounds like your amp may be locked..

also check your speaker wires from amp to speaker box then from the back of the box to the speaker inside the box you may have a short..

thats where i would start.. hope this helps

Protection light grief
Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Vibe is mediocre. Time to invest in an old school Lanzar Opti Drive amp. .A thumbs up would be greatly appreciated if this answer is helpful to you. protection-light-grief-shonxoarcym4awy4zl1imx4o-2-0.jpg

Amp blowing fuses
The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).
