I have Two CompVR in a Qlogic bandpass box. Powering each sub is Kenwoods KAC-9102D. I have each sub hooked up in 2 ohms (4ohms/coil), and each amp has an rms of 850watts for a two ohm configuration.
All I have to say is that these subs freakin bump some serious bass!!! In about a week or two, I'm gonna tear down my setup to build a new setup which consists of the same 12" CompVR, but I am gonna add two 12" L7. I gonna have everything custom done, because of the limited space I have in my Scion. I'll tell you how it goes!
