Question about Alpine MRV-F545 Car Audio Amplifier
Hi, I am having a problem with my Alpine MRV-F545 Displaying "VLT" error. I've checked wiring, grounding, subwiring, and battery. When my vehicle is on the volts displayed on amp when checked says 13.8V. I am stumped and not sure what more to do. Any ideas on what to do will be great.

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,

Fuses usually blow because of a short of too much current.
Test your wiring (including the speaker wires) and make sure they are not shorting or grounding against the vehicle chassis. Also make sure that the speaker voice coils are not shorted.
Hope this helps.

I suppose you checked all the usual suspects? Fuse, Ground, and Remote turn on?
Now if memory serves me isn't that an amp that has a digital display on the top? If so you have to scroll thru the menu items and see if it is on low pass or even off? The gains are tricky because they get louder with less dbs. but check the outputs.
if all else fails it's probalby bad.
