My son is currently running a DC level 6 18 on a Hertz HP6001. It was previously in a dc3.5k which was not nearly enough amp for the sub. The HP6001 was a huge improvement, but I still think the sub can handle more. I ordered him a Soundigital sd12kd yesterday. I'm not sure how the sub will handle 12k. Is there any single sub that can?
