Alpine Amplifier Cuts in and out on Passenger side while driving

Hello, I have an older Alpine MRV F353 V12 amplifier in my car and when I am driving the passender side (both the front and rear speakers) cuts in and out occasionally. I verified all the connections but vibrations do cause the problem. What would be the problem and is the amp even worth fixing? Thanks

Amplifier displays "CUR"

Hello anwbrown,

The "CUR" display means that the amp is drawing excessive current and the protection circuit is activating. Too low impedance or shorted speakers will cause the amp to draw excessive current.

The Alpine V12 is a Class D mono amp with only one set of speaker outputs. All versions, M301, M501, and M1001 are only stable to 2ohms. Assuming that all 6 of your connected subwoofers and speakers are 4ohm and they're all connected in parallel, the amp sees a .67 ohm load, far below it's rated impedance.

When brand new, the amp could probably operate at low to moderate volume levels without drawing excessive current. But as electronic components age, their tolerances change and they become less able to withstand excessive current or mismatched impedances.

I'd get a 4-channel amp and drive the 4" speakers off the front channels and the 6X9's off the rear channels. And just power the subs off the V12 making sure that they are connected to show a minimum load of 2ohms.

Hope this helps.

V12 MRV-1507 or Xplod? Amplifier - XM-ZR1252 good quality sound

Alpine is just a better brand in general. I have the older MRV-1507, sounds GREAT, i have had friends who has had the Explode line, but it was always a temporary system until they got something better, like the alpine or kenwood.

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,
