Viskonik v4000xd for some subs or dif amp might sell just give me an offer and let me know what you have amp is in mint condition it comes with the original box an manual.
Fusion will do around 1800 rms @ 2ohm but is .5 ohm stable daily so if you are running a single D1 or a pair of D2's .5ohm would work for you and that would be closer to 2500+ ....
