[QUOTE="kmanian, post: 7658677, member: 561298"] they showed me it powered up on a small 30 power supply at very low volume. I watched it drive a subwoofer while being powered by that small supply and took the amp. I them installed the amp in the vehicle, (250amp alt, big 2, tons of 0ga, 3 Kinetic 2000 batts charging at 14.9v). Hooked up the power, no rca or speakers and tested it to power up. It did so, so I turned off the system. Then added the RCAs, powered it up again, and it did fine, so I powered it down, and hooked up the subs (4 Sundown SA15) at 1.6 ohm starting. Set the crossover and SSF, turned off any boost, turned the gain to all the way down. I then powered up the amp again with the head unit all the way down. It powered up fine, I slowly turned up the headunit to about ¼ volume and the subs came alive albeit low volume. So I went to the amp and adjusted the gain up slowly in total about 1/6th of a from min. The subs reacted by increasing in volume, then a puff of the magic smoke of death. [/QUOTE]
