Ok, I have a 1999 Grand Prix GT. It has a 110 amp alternator and a 750 watt heavy duty battery. All I have hooked up is a kicker zx300.1(330 watts RMS) and maybe a stock bose amp. The reason I am not sure is because I dont know if it became disconnected in some of the aftermarket installation. I also have all of this hooked up to a sony head unit. I was just wondering what you guys thought the reason for the large voltage drop might be. My electrical system should be enough to handle all that huh? Do you guys think I need the Big 3? Or should I go straight to a newer battery. Or both?

Thanks to anyone who responds.
I dont have any kind of screens, gps, neons anything. I dont have the money. The power wire is the 8 gauge as suggested by kicker. The subs are wired in series and then parallel to create a final load of 2ohms. I guess I will just go with a Big 3 and see if it helps.
