Might look at some smaller amps for the subs..6-800x1 or 100x2, or a 12 that will work well off 6-800
Box does not come with them..they are d4
As far as I know it does. It has 1/0 inputs and 4x40 fusing. That is the RMS rating, not max. I have it running at 4 ohm now and it is more than enough for the 2 memhis.
