hifonics have there low rms 12 line. there like 35.00 each and can take 200rms each .i ran 3 of them sealed off of 800rms and that was to much for them
Get some lanzar maxx's. Actually pretty decent for $60 shipped or so...300 wts rms. Had a customer running 3 off a jbl 1200.1 (about 450 wts rms per sub) and they lasted a good 6 months before they all pooped out!
