    I have 2 MRD 501's connected to 2 12 inch type R's.

    Banging bass.

    All of a sudden on one of the amps the "current" displays on the amp and no volume. I checked all connections, grounds and cables.

    What next?

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

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.

That typically means the microwave circuit is not powering on so the oven turns itself off. Most of the time when that happens you will get an error code flashing on the bottom of the screen. If F3 MAG CURR. Look at my previous answers on fixing that

I've changed battery in isys+ pre amp on vintage vec500 and now tuner doesn't work (it is blinking green on note tuner no matter of tune and no note letters showing - blank screen)


Is the battery installed in correct polarity? If so- try rotate it in position to rub through potential corrosion.

Since it has a remote battery, it would not hurt to look at the installation to make sure no wires are broken. Especially the ground wire to the pickup.

It might also be a good idea to apply some contact cleaner to the output plug since it is in the power circuit. Cycle the plug in and out a few times to clean the contacts. Also some contact cleaner to the preamp controls would be useful.

Be aware some lubricants may contain silicone and that can interfere with wood finishes or repairs to the finish in the future.

Purchased Vistaquest FS-503 converter. Used two days. Screen doesn't light up and closing cover doesn't turn off the power (light continues showing through the slot for slide holder). Any easy...


take it back for exchange or a refund. A capacitor in the circuit is at fault not distributing the needed power to operate this camera

If the screen shows running in lower power as an error. I think your powersupply isn't supplying enough power to the computer, and probably needs to be replaced.

My alpine amp displays CURR and nothing coms out!This happened after i was screwing the speaker wire in and I touched the amps chasis and it made a spark. I opened it up I did not see anything wrong with...


According to an Alpine owner's manual, for that type of amp, you should be able to remove power from the amp, then reconnect power to reset the error. If it doesn't reset, either there is another short in the wiring or the amp has permanent damage and needs repair.

Amp displays the letters curr


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

Negative speaker output touched chasis of amp.


check all fuses on the unit, pull them all.
look for a way of resetting the amp.

LEAVE THE MAIN FUSE OUT TILL THE INSTALL IS COMPLETE!!!

that way you wont short a screw driver across the terminals on to the chasis.

Lights on, nobody home


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.
