Hey guys.

My Mrv-F345 displayed an Excessive Current warning. What does this mean and what should I do to check/fix the problem?

Thanks

I would assume that it means the amp saw more than 14.6vdc (or whatever it is designed to have as a maximum input voltage).

My first guess is that your voltage regulator had a hiccup or something? Possibly it is going out and allowing wild voltage fluctuations coming out of the alternator? ( a buddy of mine had the VR go out in his Ram 1500 and he started getting 17~19 volts coming out of the alternator!)

Hmmm. Could be a hiccup. Ive played about 30 min of music with the amp and thats the first time that has happend. I dont even have my sub in currently. The meter on the amps are reading 14.3ish Ill keep an eye on it. Thanks

Hmm Did it again.. Seems to high playing volume has something to do with it.

um... did you buy it new? also, go here ( http://www.alpine-usa.com/images/products/documents/MRV-F345_om.pdf ) its the OEM owner's manual. Near the bottom is a troubleshooting page, look there for your problem. also i would look through the guide to make sure everything is hooked up right

 

[Mynameismcgyver 10+ year member]

Yes it is new. I have the same manual and all it says is find and eliminate the excessive current. I know everytihng is hooked up right.

Bumptiy bump

excessive current doesn't necessarity mean too high voltage, it means that the current is too high are you running off the stock alternator? have you done any electrical upgrades? did you check the voltage going into your amp anyway?

Is it fused properly, onboard on the amp AND on the power wire itself?

It prolly means that it is seeing/pulling more current than it should...

Ill check to see what fuse is in there..Yes stock ALT......And the onboard Voltage meter on the amp atleast when I was in the trunk was around 14.2-14.4

hmm

we had the same prob with a alpine 1000M turned out the we ripped the customers install out that he drove a screw thru the ground wire and in to a speaker wire... we backed the screw out and everything was perfect.... but with this the amp would turn on but it would go in to protection at soon at it turned on and we never got and sound out of the amp.

Hmm. Well lets put it this way. My ground wire is 4 inches long and is in plain view. ANd its interesting how it seems to only do it when the volume is pumping. IM going to back the gain down one notch and see if that cures it.

And I was beginning to think i was the onle one thinking "Excessive current warning" was a warning for excessive current, not voltage.

Im not sure if this matters but i have a 30 amp fuse. The manual reccomends 60 amp, could this be the problem?
