i am trying to get rid of my Visonik 4000wrms (@ 1ohm) amplifier and a StingPro 3 farad capacitor..im selling them together for $450..so please get back to me if you are intersted...BTW, there is nothing wrong with either of them, im just not interested in these products anymore..im getting 2 15" Treo SSX's, and theres no need for any Visonik (or any other) products!
