DodgerCannon Posted February 20, 2011 Report Posted February 20, 2011 Hi all, Just wondering what to set my output voltage to on my strapped 1500d's? They have a 1.4ohm load. No access to an oscope at the moment so I'm using a DMM to reduce chances of clip. Cheers guys. Quote
fritosaregood Posted February 21, 2011 Report Posted February 21, 2011 the equation is square root ( rated output X ohm load ) so its power rating is 3000 rms at 2 ohms so sqrt(3000 X 2) that is about 77.5 volts.

DodgerCannon Posted February 21, 2011 Author Report Posted February 21, 2011 Thanks buddy, they are currently set to 80v so looks like they need to come down a little. Quote
dugee81 Posted February 21, 2011 Report Posted February 21, 2011 Yeah if your sub is wired to 1.4, each amp is seeing a 0.7 nominal load. I would try this 3000 * 1.4 = 4200 Sq rt of 4200 = 64.8VAC Quote 200a alt. by Excessive Amperage hc800 under hood & 2 Deka 9a31 in rear 1/0awg + big 3 SAZ 3000D HDC3 18" @ 2 ohm
