Question about Alpine MRV-F345 Car Audio Amplifier

1 Answer

Displays "CUR" When I turn on my radio and start raising the volume my amp shuts off at 20(out of 35) which is the limit on Alpine stereos (atleast mine). It had been doing this but after playing it at 30 for a half hour or so but know since you turn it on it starts shutting off. I'm using four gauge for the power and ground wires, thinking that it didn't have enough current, but i just read the manual's "troubleshooting section" (if you could call it that) and it says for the current display that it has too much current what could be causing that?; and its a stock car battery.

    Its a four channel amp which has a speaker per channel. How can it be too much?

    I have a pair of infinity kappa in the front 63.7i rated for 2 ohms at 75rms and the rears are 693.7i rated for 2 ohms and 75rms as well. The amp is rated for 75rms at 2 ohms so to what i understand their impedanced matched which should give me maximum transfer of power.

You probably have too low of an impedance load on ot (too many speakers or wrong kind). It has to have a minimum of 2 ohms on each channel, or 4 ohms if bridged (that means don't put 2 subs on the bridge!!).

What would make the sound turn on and off repeatedly when I raise the volume past about 17.


well, if you have aftermarket speakers with no amp, the radio may not have the power the speakers need and it clips at that volume to protect for damage. if you have factory speakers, I don't know what it would do that, the speakers would blow before the radio would clip if they were factory because the radio would have more than enough power to push them.

My alpine keeps shutting down when the volume is turned up past 20. Plus I have no sound coming out of my subs. I tried switching rca cables. And I sent my amp off thinking it was my amp. Their is a little...


so it turns off suddenly and then the next second it turns back on and starts playing

from that and personal expericance i belive that the radio system (radio and amp) is not reciving enough power

is this radio inside a car
if so what car

what i would do is attach bigger thicker wires to the positive and negative of the amplifier
direct from battery

positive of battery>>>> positive of amp
metal grounding point on car>>>>>> negative of amp
(do not use negative of battery use the metal of the car)

I have an Alpine 7525 car radio. Can you tell me what (approximately) is the normal current drawn with zero volume? Or better still, where I might get a copy of the service manual. David Brown


The current used by a car stereo is calculated by dividing its wattage by 12, which is the standard voltage for cars. This calculation is called Ohm's Law. For example, if a stereo is rated for 100 watts, it uses 8.333 amps of current.

Volume will not go passed 4


The amp requires a compatible Ai-net Alpine head unit to operate it. I bought one too and didnt know this and im still trying to put all of the peices together to create a working stereo system without buying everything all over again.

Make sure you have the speakers wired up correctly to the amp and that there are no shorts in the wires.

Bass sounds only


That is tricky one. Did you try adjusting the EQ on both the stereo and the amp? Is the Mute turned on because it will act like that? Is both rca jacks plugged in on stereo and amp?
