So you are running the amp at 1-ohm daily with no problems?yes the amps are still for sale...as far as compared to jl kicker and planet audio it would be about the same but i personally dont care for those 3 brands...and as far as being 1 ohm stable i've had a dd 9515 d2 on one jbl at 1 ohm for a month now and no problems yet and doesnt even get warm...
