My cur code come up. I assume that i need to check for the power going to the amp and make sure that Im getting engough ?

You have Malfunction Indicator Lamp lite on your dash,
I assume for some time & ask if you have checked for the
ABS Braking System Codes,since the Stability Light is on

I will assume you have no owners manual & haven't given
much thought to going to a repair shop within a couple of days
of any vehicle issue

Need the codes,then have a shop diagnose that systems problems

Could be a Wheel Speed Sensor,or not

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.

That error appears usually when the speakers (especially subs) aren't getting the current they need from the system. Check your wiring and make sure you're using the appropriate gauge wire. Too small of a gauge in wire can cause this.

Hello anwbrown,

The "CUR" display means that the amp is drawing excessive current and the protection circuit is activating. Too low impedance or shorted speakers will cause the amp to draw excessive current.

The Alpine V12 is a Class D mono amp with only one set of speaker outputs. All versions, M301, M501, and M1001 are only stable to 2ohms. Assuming that all 6 of your connected subwoofers and speakers are 4ohm and they're all connected in parallel, the amp sees a .67 ohm load, far below it's rated impedance.

When brand new, the amp could probably operate at low to moderate volume levels without drawing excessive current. But as electronic components age, their tolerances change and they become less able to withstand excessive current or mismatched impedances.

I'd get a 4-channel amp and drive the 4" speakers off the front channels and the 6X9's off the rear channels. And just power the subs off the V12 making sure that they are connected to show a minimum load of 2ohms.

Hope this helps.

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.

Check for some water in the gas.

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.

check your ground and make sure you battery power is connect properly

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.

BUT MY AMP KEEPS SAYING CUR AND I ONLY HAVE 1 TYRE R IN MINE AND ITS KEEPS SAYING CUR I REMOVE THE GROUND WIRE TWICE AND IT KEEPS SAYING IT I HAVE A 8 GAUGE AND EVERYTHING THIS **** JUST DONT WANT TO WORK WITH ME SO TELL ME PLEASE
