Check your ground wire. protection mode of any sort is usually caused by a faulty ground. I am sure that it being a boat that there could be some shock and vibration it has to endure. Just check to see if you have all tight connections. Ensure you still have a good solid ground and it should jump out of the protection mode.

Amp guard is a protection circuit built o protect the output from short circuits. Please check your speaker wiring for shorting. Once cleared your system should work fine.

In my boat is a Clarion CMD6 head unit with two rear CMQ1620R speakers, it distorts at medium to high volume, you cant turn it up load when going.Wishing to put two new speakers in the front, cannot cut...

Best bet is to take your boat to a qualified Marine Audio dealer (generally not a boat repair shop or marina), or to a good quality Car audio store that is insured to work on boats (separete insurance usually).
When it comes to boats, you need lots of power and speakers.
First thing to do is make sure what you have is properly installed. Then determine what is "distorting" .. is it too much base, purely volume or what.
Most boats we do (wakeboard style and river boats) we do: 40-75 watts RMS per speaker 4-6 speakers in boat 1 10" or 12" sub with 200-300 watts RMS Tower speaker if requested with 75-125 Watts RMS per speaker

Disconnect all the speaker leads and then hook one speaker (a new, known to work speaker) up directly to the radio using a short (6"-12") piece of speaker wire. Does that speaker work then?

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.

My Clarion APX480M marine amp cuts out at random

try to unplug each speaker one by one while playing it. There can be a defective speaker that grounds out at the speaker terminal or internally causing the amp to go into protection causing all the speakers to go out.

Amp does not turn on

assuming your amp is working fine, locate and use another radio pre out put rca and plug it into the amp and see if that will work. you going to have to eliminate what bad, the radio or the amp. If still no sound than the amp is faulty. you can use home reciever to test it also using pre amp out put plug to the clarion amp. hope that make sense

Clarion DXZ545MP in yacht . charter client usedan mp3, pulled it out and the receiver would no longer get satelite radio, It also wqould not receive satelite radio from tv receiver qwhen on AUX. The name...

Have you tried 1st to pull the unit out of the wall using the little metal "keys" to release the deck from the mounting cage and than pull the power plug AND the Satillite plug as well and wait for 10 minutes or so and replug it but first hit the reset button and see what happens. I run into this frequently with Clarion's in boats/yacht, not sure why but i guess it could be result of a voltage surge. Now the display is saying that you have a blown speaker or more than likely a wire that is grounded out. I highly doubt the charter client caused the head unit to shut down other than the simple act or ejecting a cd. We quit selling Clarion for that very reason, an abnormal rate of repair occurances. And I would wager you have the hard wired remote controls either on the bridge or in the rear at the swim platform or both locations. These too could be the problem. I can't tell you how many hours i have spent running down a shorted speaker wire. Because if one is shorted in the "slightest" you get the message "amp guard". If push comes to shove Captain i recommend a small amplifier and use only the pre-outs (rca cables) instead of speaker wire. Good luck and let me know if i can assist you because i work on a lot of watercraft believe it or not in Arizona and most are over 34' Cuddys like SeaRay SunDancers etc. good luck... Mark @ Sounds Good to Me if you want to reach me direct. I still have Clarion contacts too.. mark

As long as you have connected the ground(black) try adding one wire at a time to the live(red). If possible try connection each wire one at a time to the power line and then both together. If nothing has blown(fuses) and the unit starts working then you can try by trial & error method the remaining wires. You should be able to figure out which wire is required and if there are any extra wires like cellular phone(mute) and then decide whether to connect them or keep them open.....sodeep

Clarion M5675 won't turn on

Take the stereo all the way out and hook the black wire to the negative terminal and the yellow and the red wire to the positive terminal on a charged car battey. If it still does not turn on you may have fuse in the back of the deck. If not it's probably fried.

I have a DXZ648RMP Clarion car Stereo that says 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
