If your willing to spend the 300 then go with the kicker. They are some of the best subs out there. But they also cost alot more. My cousin has 2 rockfords that she paid 180 for and I think they were definitly well worth the money. So its really a matter of money. If you have a high budget, go with the Kickers. If your kinda tight on money but still want quality, hit up the rockfords. Cant go wrong either way
