Question about Alpine MRP-M450 Car Audio Amplifier
Try using a 4ga ground cable. Ground it to the frame of your car. And use a 2ga and a inline fuse 100amp run this to your battery. And you need a cap. A 1000 watt will work good. Hope this helps....

SOURCE: amp cuts off
You may have a problem with the power source feeding the amp. You need to check the voltage across the amplifier's B+ and ground terminals when the amp is playing/cutting off. If it's dropping below ~11 volts, you need to determine why it's dropping so low.

Ot two issues, First the AMP is going into a protection mode this means that it is drawing too much current. As netrecov said you need a capacitor, this will oppose the rapid current draw, by allowing the voltage to remain constant. However I would also sugget that you rewire the setup to manufatures specification and make sure that all grounds and supply leads are installed properly. Taking into mind the the 4awg wire has less cross sectional surface than the 2 or 0 AWG wire causing it to have more resistance this is power loss in this case (follow the specifications).
I hope this helps
