I am running a 1008W @ 2 ohms amplifier Bazooka powering 4 10″ Subwoofers… at mid volume, with subwoofer volume +4, my lights dim slightly. I’m still in the break-in period, and amp is only 1/4 gain :/ Either my amplifier is WAAAY underrated, or, well, I guess i’ll find out soon… And the digital read-out didn’t work at first, but came on about a week ago.. ?weird? If there is any change, I’ll re-review it..( Still a pretty good, inexpensive cap )
