[QUOTE="fithwheel, post: 8677408, member: 674179"] Birth sheet on 750 typically close or right at a 1000 watts at 1 ohm but since it is a constant power amp even at 2 ohms would still be around 900 watts. Requires 8 guage same as the mini 4 ch t amp. So wouldn't need any more than 4 guage to a distribution block. Birth sheet on that t 5 ch amp is right around 700 at 1 ohms. Around 600 at 2. I'm using 2 300 watt rms subs on mine. After box rise they're really not getting enough power to get the most out of them. Considering I don't want to mess with my electrical the t 750 would do a little better on them without doing anything besides big 3 which I've already done.
