I have a Hifonics Colossus XXII that I am running to two Eclipse SW9152. With the ohm load, they will be seeing 1100rms each...I am in need of an alternator now. I am looking between the DB electrical 220 amp, and the 250 amp. Will I be fine with the 220, or is the 250 NEEDED? The search feature doesn't work, so i couldn't look too much.
