I just got the new Alpine Type S 4 ohm dvc subs that RMS 300 watts. I have a JBL BP600.1 amp. I read that it is "2 ohm optimized but can run a 1 ohm load with ease" which is what I would be running my subs down to. Should I maybe take them back and exchange them for the 2 Ohm DVC type S subs or will it be fine at 1 ohm?
if you want to be on the safe side, you should take those back and get the dvc 2 ohms. then you can wire it to 2 ohms. i don't know what the deal is with those jbl amps saying that they can handle those low loads of ohms, but i think 2 ohms would be safer.
The JBL BP600.1 and 1200.1 run stable at 1 ohm. However it is the same amount of power as at 2ohm. Will be much more efficient at 2ohms. If it were me I would take them back, but you won't be hurting anything if you don't.
