I currently have my stock battery and stock alternator in my 2000 dodge stratus. I will be upgrading the alt and the magic 3 wires before I do anything, but I am looking into this power invertor:
I will eventually be running either 2 ps-2's or 2 x-box's, 4 LCD screens, and a dvd player. Not too mention subwoofer amp, component amp, H/U, and the various other things.
At what point should I place a second battery in my vehicle (possibly deep cycle marine battery?).
I realize that the battery is often not used when the car is running, but if/when the amplifier can't handle the load and things start to dim, wouldn't it be better for those items to place a load on a different battery than my main one? Not too mention if I happen to let someone watch a movie and I don't want the car running, I'd rather kill a second battery than need a jump start...
Also, everyone is throwing around "red top" and "yellow top". Are those specific brands? I don't mind buying batteries at sears, walmart, or wherever as long as they're decent, but are the yellow tops deep cycle and the red tops not?
Thanks for any information. One more question, when I install the second battery, it needs to be well ventilated... If I ran it in my trunk, would I need to somehow seal it from the rest of the car, but yet run vents to the outside?
