[QUOTE="Sguirrelfeather, post: 8527333, member: 668995"] Amp is an FSD FZ2600. It's rated at 2600 at 1 ohm, but dynoed well over that. I'm running it on two Soundqubed HDS208 wired for 1 ohm. When I say 75%, it's not like I just turned it there and said ok. I used a DMM (no access to an o-scope) and set the voltage to reach 37.42, which correlates to 1400W at 1 ohm. This just happens to be about 75% of the max gain. Voltage at the amp, with truck running and amp off, is about 14.3. When amp is hitting hard, it's about 13.7.....it's a long run of wire. Probably 25ft or so, because it's a Ford Excursion. Because my HU only has four RCS-outs, I did have to split the cable off. I don't have a processor or any kind of crossover before the amps. I've read this should not make a difference, but I'm wondering if it would be possible if the HU isn't quite putting out what it's supposed to. [/QUOTE]
