I searched and couldn't find the answer I was looking for so if someone could share some knowledge on the subject I'd really appreciate it. As many of us know, JL slash series amps do rated power from 1.5-4ohms. Do you think with impedance rise I would be safe running a 12'' d2 Nightshade at 1 ohm off a 1000/1? I don't know much about impedance rise so I'm hoping I can learn a little by making this thread. The enclosure is 1.5@35 incase anyone is wondering. Thanks for the answers!
