Ok I have two 15 inch kicker L7 solobarics and two hifonics 1600 watt amps. I have a dual flip out touchscreen dvd player as my head unit. I am running 2 gauge power wire and two 1 farad capacitors. the ground wire is 4 gauge and running to under the rear seat bolted down to a metal lip piece. Im thinkn i need a better ground. when the truck is off it doesnt make a noise but as soon as i start it it hums with the engine and hits a little when i open the door or try starting the vehicle while the system is on. HELP!!!
