SOURCE: amp guard

Other sites I've read about this problem suggest that first you try checking the wiring to the speakers for a fault to ground OR you have speakers with too low impedance. If those check out ok, the unit needs to go back for service.

SOURCE: Ihave power but no sound

hi bign,

try the following things:

1:Try checking your ground connections, if they are good, then try regrounding the head unit to some bare metal in the dashboard, you could have a problem with the factory ground.

2:try looking at your speaker connections, sounds you have a wire grounding,try disconnecting all speakers and see if it does it. If not, try connecting one at a time, see if you can single out the speaker thats causing the problem

and also check to make sure the speaker terminals are not touching any metal, which is unlikely, because they are factory speakers.

god luck! and please rate this solution!

SOURCE: it says amp guard when i turn it up

Sounds like you have speakers that are wired incorrectly. Most car stereos require a 4-ohm load, if you wire two standard speakers in parallel it will create a 2-ohm load and cause this condition.

SOURCE: clarion dxz545mp amp guard

, the message you are getting is "amp guard". This is the mesage it will display when a short in a speaker wire or speaker with low impedence is hooked to the internal amp and sends it into protect mode, shutting down the amplifier section while the rest of the unit continues to work.

check all of your speakers

When i turn stereo on and there is no sound and AMP GRD comes up. how do i sort this out


The amp needs a ground green wire. Attach it to a metal object with a screw. The wiring harness will have a green wire sometimes with a factory installed ring on it to be able to attach it to a ground

ITS SAYS AMP GRD


All you have to do is press the source button for 10 seconds till the power goes off and it only shows the time. Then turn it back on. It should be working then.

Why does my radio say amp grd when there is no amp hooked up and it was playing just fine tell now


sounds like you need to check your speakers and/speaker wires to make sure you don't have a short to ground or bad speaker. if those check out, you may have a bad output ic inside of the deck.

Installed and no sound or nothing


Im guessing you have an amplifier if not check the cd player ground " AMP GRD" means amp ground is faulty. In the event that you do have an amplifier check that ground wire as it's most likely the problem.

Car stereo receiver


Maybe the owners manual would help. It says you can adjust the sensitivity of the AUX input through a menu. It sounds like the AUX sensitivity is just set to max. Look for the 'to change other settings' chapter, instructions are in there.
If you don't have the manual, find it on the official website.
