The subs cant handle all the power you got it set on turn off all the settings and then turn off your car and remove your face plate and then it should be ok. it does that because the subs cant handle the settings you might just have them a lil high

Re: alpine mrd-m501 amp
Disconnect the speaker wires from the amp, then try it again. If the error message doesn't appear, try connecting the speaker wires back to the amp one by one.
The error message is due to some sort of overcurrent in the amp. If the error does not go away when the speaker wires are disconnected, the issue is most likely with the amp itself and will need professional repair.

Shorted or low impedance outputs can cause the "CUR" display. Power down everything and remove the speaker wires. If it will then power up without the display, the problem is probably a short in the speaker wire or voice coil, or the impedance load is too low. If there are multiple subs, reconnect them one at a time to isolate the bad one and then correct the problem. If the amp works properly with either of the subs but not both, rewire the subs for a higher final impedance.
If the amp still displays "CUR" with the speakers disconnected, there's most likely an internal fault that requires component level repair.
have you disconnected all inputs and outputs on amp and retried starting it power only? if so your amp has an internal solder bridge and must be repaired by authorized repair center. Repair it or replace it at wholesale price from www.godspeedaudioheaven.com
Hi. If you shorted (touched) the speaker wires together, or let them touch the chassis of the car, then it may have locked out. Just turning the amp off and back on will fix this, so it sounds like you have done damage to it. Most amps have a speaker relay which gives a click sound when you turn on. If there is no click, then it may have a power supply failure.
Appears to be an issue with current. Is the speaker the correct impedance for the amplifier ? Have you confirmed there are no short circuits in the wiring ? I'm not familiar with this particular product,
The alpine catalogue gives recommended amp/speaker combos. If you don't have an aplpine sub, then look at the specs and find a similar one. You may be trying to load the amp too heavily and it will protect itself.
OK, It looks like you may have an internal problem. I must say from the begining if you do not have a background in electronics take the unit to a qualified service center. Now it sounds like you could have a power supply problem if you have power coming in onpen the unit and with the use of a schematic find the main voltage rail and test from there each test point and make sure it matches the schematic value. Look for burnt circuit tarces nad if you find the remove them and jumper with re-trace wire.
