Silver Member Username: Van_manBoston, MA Post Number: 391 Registered: Mar-06 | neither. put one sub one one channel. 2nd sub on 2nd channel. If you seies them load will be 8 ohm load. in Parallel it would be a 2 ohm load. So you would have both subs on 1 channel at 2 ohms at 250 watts plit by 2 = 125wrms to each sub. If you had four subs you could use both channels like that. but only 2 subs, the best is 1 sub on each channel. Or use 1 sub and bridge the amp for 1x500@4ohms. |

Bronze Member Username: Thejoester101Post Number: 19 Registered: May-06 | But this is a 1 ohm load. I need a 4 ohm load. |
