yea i just want to run it daily but i dont bump all the time just every once in awhile, im waiting to see on a few deals if i get some 15s at d4s, see i have 2 12s l7s right now and there 2 ohms and i had a kicker sx1250.1 on them for awhile and they bump good, but now i am getting a kicker zx2500.1 which it is rated at 4 ohms 1250.1 and 2 ohms 2500.1 so since that if i got these 2 d4 15s i would be bought the same setup as i had before just 2 bigger subs, i probally wouldnt notice a difference, thats why i was asking cause it would be pointless to me, but i am broke right now and i have to try and trade my 2 12s for some 15s and i kinda have to take what i get lol if you know what i mean thanks guys for all the help
