What's important to know is the amplifier current draw when the volume is cranked up. Then go from there to determine the required wiring gauge and alternator current rating. Of course you also have to factor in current draw from lights, ignition, A/C heater blower, etc.

To do that you will need a multi-meter with a DC current clamp or some type of clamp that will output xx millivolts per DC amp to a voltmeter.

Hope you turn down the sub volume when driving through the neighborhood. We've got a guy here who's about to have lacquer thinner accidentally spilled on his car's hood if he doesn't stop thumping down our street at midnight!

Make sure you have good enough grounds as well. If you added a significantly higher output alternator, up sized your power wire, but didn't increase and check the ground connections from battery-frame, frame-engine, and engine-body, you are going to have problems.
