[QUOTE="Trixter, post: 354907, member: 542668"] I have ran dual battery set ups for about 9 years now. I have never used anything to seperate them. I have used batteries of different sizes (same brand though). I have never had any problems. Connect the 2 pos and ground each neg. It's a good idea to put a fuse of even a fused link at BOTH pos incase somethin happends to the cable in between them. If you have a system that really needs two batteries, then chances are you shouldn't be playing you system without the car running anyways. [/QUOTE]
