2 08 kicker 15' L7s 4 ohm wired to 1ohm.. My speaker friend didn't get to adjust them yet cause he was at work, but he told me to adjust Gain by ear, subsonic on 30, bass boost all the way down and sumthing else. My daily driver is 01 explorer 0 gauge wire, 250 amp fuse under the hood kinetic 2500Hk in the back, and 150 fuse in the back. My deck is a clarion 6V pre amp output
