i ask as i have an EF Fairmont, fairly standard, but have just purchased a factory 8" free air sub from a ghia. I really need to know what type of amp will be optimum to run the sub. System already sounds good, i havesony GT700 head, soundstream 6.5's in the front and 5.25's in the shelf, great high and mid quality just a little lacking in bass.

Thanks, Josh
