Question about Kicker KX400.1 Car Audio Amplifier

Protection light on

I had my amplifier for about a year but I hardly used it, most of the time it was unpluged or out of the truck, about 4 months ago I pluged it back up but only the protection light came on I tried in another car and still have the same problem. What can I do or where can I take it to get it fixed.

The most common reason for an amplifier to go into protect is shorted output transistors. Class D amps are generally a bit more difficult to repair (especially those that use surface mount components). I'd recommend you take it to a local repair shop to have it repaired. If you want to try to repair it yourself, it will be time consuming but I'll try to help you through it.

SOURCE: protection light on

The amp probably has blown output transistors and is in need of repair.

Call some of the better car audio shops in your area and ask them who they use for repairs. If several use the same shop, it's a good indicator that they do good work.

Receiver keeps going to standby

I don't know about the newer receivers but this sounds like an arching OFF/ON power switch that was a problem on Pioneer receivers years ago. I would bypass the switch and see what happens.

1. Unplug unit from wall.
2. Jumper two wires going to off/on switch using alligator clip with insulated boots on clips.
3. Plug amplifier into disconnected circuit breaker/fuse protected AC strip.
4. Plug AC strip into wall outlet, turn AC strip switch ON and see if problem disappears.

Try unplugging all of the speakers and see if that amp is still distressed. If it looks clean and happy start adding speakers until it returns (or not).

Is something wrong with my amp if the protect light stays on or is it the wiring?

It could be the wiring. Sony amps will go into protection if the ohm is to low. They usually like to see 4 ohm or higher. Unplug your speaker wires and see if it still stays in protection. If it does could be an internal thing in the amp. If it isn't rewire subs in series not parallel.

The problem, whatever it is, has resulted in a short circuit condition which has activated the protection system.

The set will need servicing in all likelyhood. Do a hard reset to see if that will restore operations; if not, you will need service. A hard reset is easiest to achieve by unplugging the power cord for 4 hours or more. Then try again.

If the hard reset does not help it will likely cost around $150 plus the house call. But, a tech will need hands-on measurements to isolate the problem to the exact failing components.

Xplod XM-DS1600P5 red light

For some reason it has gone into protection mode to limit further damage to the amplifier. Remove the subwoofer wires and power on to eliminate shorted voicecoil. After checking all wires for continuity to ground, a service tech will be required.

Protection Light coming on with loud volume and power

It's most likely that the over-current protection is tripping at high power. At lower voltage, the amplifier can't produce as much output power and therefore can't produce enough current to trip the protection circuit.

You need to check your speakers to make sure that they are not shorted. With an ohm meter, the resistance across the voice coil shouldn't read any less than ~90% of the rated impedance.

If the speakers and the wiring are OK, the amp may have an internal fault causing the amp to go into protection.

Let me know if you have any other questions.
