Hi SPDGOD,

 

Could not find exact, but close manual.  It is the MRP-M450 mono block amp from alpine.

SOURCE: alpine mrd m500 amp is not pushing my 12 in infinity sub

If you have a dual voice coil sub, make sure that you have the positive and negative terminals connected properly. If you have ONE of the coils wired backwards, it will cause the speaker to produce little or no sound.

Have you set the gains properly?

Are you sure the amplifier is receiving a strong signal from the head unit?

Have you tried it with a different speaker?

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

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

How to get amp status to come up on the screen of alpine d 310


you have to have an alpine kce-510m amp link module. You must also have a compatible amp, such as mrd-m300, mrd-m500, or the mrd-m1000. The amp link module plugs into the (ext) plug on the iva-d310 and the other end of the cable into an alpine kce-060m y-cable. The shorter of the y-cable plugs into the amp with the lowest id #.

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.

My amplifier is plugged but doesn`t bring a sound why?


If your are certain that you have a signal going to the imputs of your amp and you are certain that the speakers are OK and you have not turned the gain control all the way down then that just leaves a fried amp. Good luck.
