  • How do you know that amplifier is overheating? Based on the stats for the amp (75W x 4 @ 4 Ohms, 140 W x 4 @ 2 Ohms), the maximum current your amp will draw is about 30 amps. 10 gauge wire is rated to deliver up to 100 amps @ 12V, so 9 gauge wire is plenty. 5 gauge wire is more than plenty. In any event, if the amp is overheating, it's because you are either demanding too much current (i.e. cranking it too loud) or it's not getting enough cooling air circulation. Did you install it UNDER the carpet in the back seat floor? That would probably do it. Generally, you need 1"-2" of airspace around the amp to allow cooling air to circulate. Good luck.
