Re: 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?

Ok i got a mtx 12' 500 sub matched to a alpine mrd-m500 mono amp. The deck powers the 4 speakers, as i turn the volume up on my deck (alpine cde 100) the sub/amp cuts out at around volume 20-22 and E-3...

Sorry,after rereading your problem,I gave a wrong answer.Do you have the deck sub RCA pre-amps connected to the amp,then the wires from the amp to the sub?If you do,you need to check what the sub and amp are rated as such as,peak or rms.They are 2 completely different meanings.Greg

That is a code to inform you of an issue, and to help direct you to a particular area of concern

HOT & E-1 = both for heat issue

E-2 = for a voltage issue

E-3 = for a current issue.

While yours is a current issue, that reflects a problem with your input or output signal pairs. You should disconnect the subs at the amp, then operate the unit as normal to see if the code reappears. This is the start of your process of elimination, where as you will be able to determine the general location of the issue, weather it is before - internal - after the amp, hence If after the subs were disconnected, the code did not return then it would be obvious that you should focus on the subs and their signal pairs. troubleshooting in small increments until the issue is discovered.

Hope this helps...Good luck

How to unlock my alpine mono power amplifier mrd m500?

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.

Try switching the lowpass filter down to 80hz or lower, then adjust the bass boost to your liking.

Alpine amp mrd-m605

The amplifier probably has shorted output transistors. If the amp gives the same error message with the speaker wires disconnected from the amp, the amp needs to be repaired.

Error codes

One of the parts went bad, and you need to take it into the dealer. The way Alpine's error codes work are very vague. E-3 could mean the psu fried, a resistor went bad etc.
