Ok im running currently a 1720 watt audio system on my 1999 mits eclipse. It runs fine with no problems My battery never dies. Will i be ok adding an extra 500 watts to it cuz i was running a 1000 watt mono to my sub but i bought a 1500 watt mono and im switching it out with the 1000 mono. I just dont want to be driving and my battery give out. Will i be ok?
