yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

What is cur code


Hello, i had the same problem, double check your grounds, thats all it was.
For reference, the error code "CUR" means in the manual (http://www.analogstereo.com/pdf/alpine_mrd_m1000.pdf)
• The amplifier has been shutdowndue to excessive current. • Find and eliminate the causeof the excessive current, thenturn the power off.
Please Note: Underpowering subs can make your amp goes to protection.

How do you get it out of cur mode


Hello whatup_132,

If the M605 fails and displays "CUR", it means that there is excessive current to the amp.

The most common causes for excessive current draw is operating the amp into a lower impedance than it is rated to handle, shorted speaker voice coil(s), and/or shorted or grounded speaker wires.

The amp can operate into a load no lower than 2ohms. First power everything off and disconnect the positive amp power lead temporarily (easist way is to just pull the fuse). At this point you should ONLY have the ground and remote connected. Reconnect positive (insert fuse) and turn on the vehicle ignition and your head unit. If the amp still displays the "CUR" error, the output MOSFET's are probably defective and the amp requires repair or replacement. If it powers up normally, reconnect the speaker wires until you locate the faulty one, and then correct whatever is causing it.

Hope this helps.

CUR display


Hello yte1771,

You can download the manual from Crutchfield.

The "CUR" display is an indication of excessive current and is most likely caused by too low impedance or a fault in the wiring or the amp itself. It's probably not your cap.

Hope this helps.

Alpine v12 amp displays CUR and cuts itself out when i turn up the volume????


I'm not specifically familiar with that model but I'm pretty sure the"CUR" is indicating under current or not enough current. what's happening is your amp is under load and doesn't have enough power so it shuts down rather than smoke. I would suggest you run heavier cable from the battery to the amp and add a giant cap so that when the amp surges the cap will compensate for the sudden draw. This is not a cheap fix but if you install heavy duty power cable and a quality giant capacitor (2 farad) you will be able to push the amp until your speakers catch fire and your amp will be fine.

CUR is showing on the display


The amp will reset when you cut the power off to it. Disconect bat for 30 sec and reconect. But to be honist with u if the wire jumped out and grounded some how during a high level, there is probley internal damage done.

CUR showing on the display


This means too much current, find and eliminate cause of excessie current and turn power off, also possibe power and ground are not big enough .Recommend 4guage wires

CUR showing on the display


Have you measured the DC resistance of the woofer to determine if it's OK? You will need to disconnect it from the amp. Check each voice coil individually.

 

If you disconnect both speaker wires from the amp, does it still show an overcurrent condition?
