[QUOTE="Jhicks, post: 8584185, member: 673274"] Skar 800.1 American Bass XO 1244 dual 4 ohm 400 watt rms I have the subs wired to 1 ohm. Calculation says I need to set at 28.28v to be at 800 watts. When I try and set the gain with the DMM using a 50hz tone it has me setting at before half way on the gain with the speakers attached to get the 28. If I try reading w/o the speakers wired it has me around 1/3 of the way up to be at 28. For the hell of it I tried reading it at Max w/o speakers and it reads at 55.5v. Max with speakers it reads ~38.78. So I set it to the 28.28 with them hooked up and they sound kinda pitiful. What am I doing wrong?? In my mind this amp should be at 800 watts around max gain not before half way. I've had regular Rockford 12s on 300 watts sound better in a trunk. I mean I know these aren't top of the line but 400 watt rms in a hatchback should be shaking something not a slight tickle. Sent from my SM-G935V using Tapatalk [/QUOTE]
