Question about Alpine MRV-F357 Car Audio Amplifier
Hello, We just installed this amp and all of the channels work fine but in a short period of time and even w/o the sub channel connected, the amp heats up very quick and it melts fuses ( it burned one fuse, but the other one melt but continued working). And after a while it turns off. Hope someone can help me. thanks, Vic
It sounds like the power cable you have may be too small. If you're using an 8 gauge for both the power and the ground, try switching to a 4 gauge for both.

If your speakers are wired for an impedance below 4 ohms mono or 2 ohms stereo, that would make it shut off. If you have a speaker wire shorted to ground, it would also cause the amp to go into protection.
If the speakers are not the problem, it may be shutting down because the voltage at the amp is dropping too low.
