well this is my everyday driver so i want it to sound good on music, so i guess i'm doing good. as for my electrical i have a 250hi output alt, a 40fared cap, orbital bat, and big 3. all 0awg wiring throughout my truck, even from the alt to the batt. grounds included. also my wife was competing in the show in a 99 explorer, sub wise she's running a single t110 of off a punch 600.1bd, she hit 139.4 in stock 0-600 class, she hit 151.2 in super port wars, which i dont think is too bad for one sub in a daily driver. as for her electrical she has a stock alt and stock batt, but she has a 1.2 fared cap.
