[QUOTE="audiolife, post: 2326997, member: 541383"] if your alt works even a 1400 will power a system by itself for a long time. my set up (which isn't big though -600 watts) i can charge a battery (for RC cars) and listen to music key off for a good 30 min un hook the charger and start my truck up easy and still not have any flickering(not full blast but you can still hear it for a good distance windows down). i usually did that 2 times then go drive to a restaurant then back to the track and do it 2 more times. music is dynamic , the charger is a constant 7-8 amps.its sort of hard to throw a real time on it with a dynamic load. i have seen 5 hc 600s power a 3500 watt system at shows for over 40 minutes before you notice dimming (again not cranked but well above a moderate volume) there are alot of variables though such as impedance rise and the actual music it self. just know im talking in terms of minutes without an outside power source even helping.
