You want it per channel into 4ohm, then 4ohm mono?That would be greatly appreciated!!!
X3look into the old us acoustics USA series amps. the USA ones only, not the USB or USX's. you can find em on ebay from time to time. great zed built amps and super cheap.
They're pretty efficient from what i've heard, maybe you just have a weak charging system. Besides, that amp makes in excess of 2000watts, it's only right that it needs the juice.I have two 07 MD3D love the amps the only problem is I need to upgrade my alternators,these amps need alot of juice to get the most out of them.In terms of the Xt line they best way is listen to them yourself..The NEw US AMPS are still up their with the best of them.
