Jus got my new 2500d amp hooked it up but i believe it should slam harder than what it is. To get the full potential do i really have to run power and grounds to both supplies on this amp. Im running two red top optima batteries. One in front the other in back. Please help!!!!!!! //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif
