gmoxley1 Posted August 8, 2014 Report Posted August 8, 2014 So i have what i think is a pretty simple question. If i have a regular flooded battery as a starter battery can i use an XS power battery as a supplement to my car audio system. for now it would be a saz 1500d at 2 ohms, so only about 800 or so watts, which i know is not much for that battery but when i get some different subs and wire to 1 ohm ill be around 1500 watts. my main question is would i HAVE to run a relay as to separate the batteries when the car is off? would their be a constant push/pull from the two batteries that could potentially cause the batteries to drop below 12.6 while im not using the car. the longest i go without using my car is about 4 to 6 days. its rare that i ever go a full week without at least cranking it and letting the regular battery charge a bit while i listen to some music. Thanks in advance to everyone who answers!
