I would do the yellow top up front, but need to do another battery in back, I am selling one if interested......Check the classifieds. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
If not, at least do the big3 and use 0/1g wire......again check the classifieds.
Those Rockford amps take a lot of power to be efficent. IMO, I would have kept the Sundown, but that is just me.
