Hey guys. I've got an Alpine MRP-V300 on my hands that's having a bit of an issue with the front channels. When you torque down the terminals you get nothing, but if you just touch the wires to them you can get then them to make music. I'm wondering if there is any way to fix this problem as I'd really love to throw this amp in my girlfriends car.

Thanks guys!

 

Take apart the amp and resolder the connection to the circuit board. If the wires are connected firmly to the amp, wiggle the wiring to see if it starts to play or not. This should verify the problem in the amplifier or not.
