Disconnect all of the speaker wires at the amp and turn your system on -if the amp stays on then you likely have a roasted coil in one of your speakers somewhere and causing a short which is shutting your amp down into protection mode-if the amp wont stay on with nothing connected to it then you have probably roasted something inside the amp and uhhh good luck bro

My mrv f345 amp reads CUR on display screen and has no sound.


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.

Just make sure that the speakers are the correct impedance and properly rated. If not, the amp can be damaged.

Alpine MRV-F345 VLT ERROR


Hello,

This is an indication of a voltage error, I have seen this when the voltage regulator or the car battery is begining to have a problem supplying enough current to the amplifier. Check the voltage levels with the amp turned off and then turn on the amplifier, if the voltage drops this means that there is poor voltage regulation and this may mean that you will have to replace the car's voltage regulator.

I hope this helps,

Thank you,

Error code on alpine mrd 500


It's a current overflow in the system. You can also get this message if the voltage is too low. Also it can mean a short in the speaker cable. E3 Error is a general error "eccessive current overflow". Check the fuses, I believe there are 4 in this unit but not sure. Check your crossovers. I hope this helps you out. Is this a new hookup or did you buy anything new or change anything?

Over heating


you trouble shoot the problem by opening unit and force-powering fans to test for overheating during "being used loud for a few minutes". Read the fans' label for proper voltage to apply and proper polarity. I am guessing the fans will run on car battery voltage of 12 volts. Also, attempt to close up the unit to simulate real conditions. There should not be fuses for the fans. If unit is now cooling, then look for faulty thermistor, which turns the fan on during rising temperature. Once thermistor is located, a fast test is to "jumper" its two wires to simulate turn on.
