soundqubed amp

I have a soundqubed 4.5k and I've never had this much power so all my other amps just had one ground and power wire terminal, does it help if I run both of the power and grounds, will it make any difference?

Item(s) for Sale: Brand new in box soundqubed 2200 as in never mounted powered or anything. Had it about 2 weeks and was going to use it on a single zv4 but i want to try a brazillian amp instead so i have no use for it. Comed with bass knob and the wire. Still have instructions, Original box...
