Pinoeer Radio Head Unit says "AMP ERROR"

[Vincevox]

Hey guys , I wanted to ask has anyone have any problems with their head unit saying "AMP ERROR"? It would play for a couple of seconds and then would die out? I have a pioneer (not sure of model) radio and I have already checked the wiring and I saw that there was no exposed wires so I am thinking that none of the wires would be grounding incorrectly. but if anyone has any ideas that would be great!

If these are one of the newer model head units, then the amp is probably not seeing something it likes and is letting you know.

My suggestion is to disconnect the speakers and see if you still get the error. That will eliminate the speakers being the cause of the problem.
Depending on how your harness is setup, your next step would be to disconnect the wires from the connector to eliminate any unseen wiring issues.
If you still see the message, you have an internal amplifier issue.

Thank you for your fast reply! i will try to disconnect and play with it. And what would cause an internal amp problem?

No problem!

Usually it is a bad power amp IC, but there could be other things like bad solder or open resistors.

I work at a car audio shop, amp error means that either the onboard amp is bad, or most likely, the ohm load between all 4 channels is uneven. Pioneer headunits are only 4 ohm stable and if you only have say 3 channels being used it will cause the headunit to overheat and eventually display that message. Grab yourself a voltohm meter and disconnect the speaker leads from the headunit and check for ohms and continuity for all 4 leads going into the car.

So update...

I checked the wireing and everything looks okay , and I do not know what happened but it is happening less now. It will happen on occasion but it has not been occuring too often anymore.

Not sure what happened but will save up for a whole new setup if anything.

Sweet thank you! That I will do before doing anything now!
