Pioneer AMP ERROR (How to fix) a troubleshooting guide

So if you have a pioneer head unit and are getting the pioneer amp error this will give you the info you need on how to trouble shoot the issue and find out what is causing this and if you need a new head unit or not.

This video was actually very helpful! It turns out the screw from one of the expansion clips from my trim cable found it’s way to a speaker wire and that was enough to cause that issue

When I put my window down, the unit would cut out and I would get the amp error. It turns out that the tweeter wire was getting hit by the window and the wire insulation was actually cut from the window going up and down. Thanks for the tip. All good now that I rerouted the speaker wires.

[@Firehornet21]

Thanks for this. Been at it for like 6 hours and finally removed all the speaker wires coming out the head unit. Still got the amp error. Need to fix or get a new head unit.

Great description mate. I’ve got this issue but unfortunately none of these seem to be the issue. The power ignition (red) wire is my issue. If I connect to an ignition line after around 50 seconds the error comes up. But if I connect that wire directly to the battery it is fine. Obviously that’s not ideal as I will drain my battery. The internet after countless hours isn’t helping at this point. Hopefully I find a fix. Thanks again

Run the power wire to a switch to turn on and off, as long as the yellow power constant has power all the time the memory will be saved. Could also just run it straight to the fuse panel grab a fuse slot tap fuse and go to the radio fuse.

[@Dr_Decaf]

this was happening to me. i have a high voltage system and my fuse blew without me knowing. my music stopped working and once i replaced the fuse and charged the batteries it never had an error again. so i assuming it has the same effect on the amp in the radio when your voltage is too low. it’s trying to draw power it doesn’t have and therefore shuts off. that’s what happened with mine.

[@SmittysWorld]

That’s very interesting situation glad you got it fixed and thanks for the insight to your issue.

I’ve had my radio for over a year now and all of a sudden one day I hit the break and I noticed a heavy static and once I let of it was fine I checked if wires were getting pinched behind the peddles and it won’t..one day I go to play my speakers and they wouldn’t play and it was some static hear and there but no sound in any of my 4 speakers my subs play fine but after a little bit with the radio trying to play it shows a amp error..I thought it was a ground issue so I cut the ground and made a new ground and is doing the same thing..any ideas on what to do?

[@ProfessionalTurtleEater]

I have no idea

[@Locsta6711]

Hello ya bro I would of never thought it would of been becuz of another speaker I took out my whole system numerous times thinking that was the prob. But one of my 6x9s one of the solder broke and was touching ... Now I'm back slappin the humps fa shoooow thanks man

[@Zackattack-rc8ek]

I been having this problem and replaced all the speaker wire put new sub wires in and its still not working and i just put the pioneer radio in today i have q speaker popping in the back could that be it? Oh and the suns work too just the car speakers dont work and i checked all the wires with a multimeter and there fine like all the speakers but just no sounds

[@SoyChukii]

did you ever figure it out ?

[@derbycityracing2997]

So the amp error on a mvh-312 could just be a result of a bad speaker ?

[@SmittysWorld]

It’s possible

[@nickparish8291]

So I was hooking up my subs last night. I had everything else hooked up right but when I went to hook the ground wire up from the amp, the radio just cut out and it said amp error on my radio. Do you know what it could be?

[@SmittysWorld]

Unhook you amp see if it goes away could be a bad amp.

[@trevisjohnson2696]

What about if. The speaker is. Cross up. Can that happen

[@666newguy]

hello my name is robert I'm getting the amp error on my pioneer mhvs21bt, I have checked the wires to my aftermarket door speakers and they are fine on both sides but I get no sound from them, yet I get sound from my sub. I checked the headunit and no burning smell or anything. plz help if you can

[@curbside01]

I get the Amp error when I have the volume below 52 lol any help it other wise works

[@SmittysWorld]

Could be bad speaker try one at a time

[@romeriodossantos4025]

Eu comprei um desse aí e não tá aceitando o pen-drive fica só pedindo verif USB como faço pra ele aceitar o pen-drive

[@treycleaveland778]

Thanks man. Mine was my new speakers as well

[@stormygalemarko]

Thanks for the info❤❤

[@EthanknottDOJ]

My head unit is brand new and if I play a song with hella bass it does it

[@rapalaray1701]

Same. Trynna figure this shit out. Its all clean signals and everything is fine. Good voltage, on a 3k salt amp.. everything fairly new but still gives amp error.

[@stacy-anngayle4174]

What if you are not hearing anything at all what do you then

[@SmittysWorld]

Start by checking the radio with a known good speaker outside the vehicle

[@lynnscarr5403]

so, I have done the trouble shooting with the cars speakers, still get the message, Amp Error!

[@SmittysWorld]

Have you checked for the error without any speakers hooked to the wiring harness just the power wires and the ground?

[@lynnscarr5403]

@@SmittysWorld not yet but i can thanks, this unit was given to me, so im no hurry really

[@ceciljones1248]

My amplifier error only came on after 15 to 20 minutes so I'm thinking what has happened I ran 3 4ohm tweeters on a 2ohm amplifier it only started when I did it want to say it is a speaker over load when I turned the volume up that's when the amp error occurs I will try it out with just a 2ohm load

[@SmittysWorld]

motherboard is overheating probably from to much load. Raise the ohm load or remove some speakers see if that helps. Also could have a bad coil on a speaker making it short as it gets hot.

[@ceciljones1248]

@@SmittysWorld I did and it hasn't did it so far I think the ohms is two low I was being lazy and didn't want to hook up another amplifier or run my new tweeters to my head unit thanks for the response 👍

[@ceciljones1248]

OK I went back to a 2ohm load hasn't shut off of 45 minutes of play time I have a ds18 320x4 channel amplifier class d I think that is what saved it from blowing up I have a old school two channel lunar amplifier on 4 infinity kappa in the door and back deck thought it was the lunar amplifier because it is ran down to one ohm it gets hot but doesn't shut off and I had that amplifier for years it was made in the United States in Louisiana and that think is bullet proof you know it's hot down here in Houston?

[@reptilezombie9335]

Bro where you located at?

[@patrickwarden2933]

Great video

[@SmittysWorld]

Thanks!

[@thomasdeane938]

I have rcas for all speakers and no wires at the back are touching

[@thomasdeane938]

Still getting it

[@SmittysWorld]

Could be shorting internally unplug all rca see if it goes away
