Not a noob question at all. :thumb:Noob question, i know... I have a 2011 JK. I have the RES radio and one JL Audio XD400 amp driving the tweets, dash, and sound bar speakers. Next week I'm having a second JL Audio amp (XD300) to drive my new Stealthbox.
In the future, I would like to add up to 2 sets of accessory lights up front - a set on the front bumper and a set of windshield mounts. I have had vehicles with big stereos in the past, and I know you can overtax your alternator with too many electrical add-ons.
I've read a number of dual battery posts in this forum, but I can't figure out the reason for them. Is a dual battery system just needed for redundancy - in case your main battery dies, and you want to jump your Jeep from the second battery? Or, is a dual battery setup needed to run a winch?
Again, I'm just checking to see if running two amps and two sets of add-on lights would require me to get a dual battery setup.
Most people who get a dual battery system use it for camping, running winches and on-board air systems, as a safety backup when they're in the stix, etc.
I don't think you'd need one for a couple amps and aux lights. However, if you decide otherwise, or think you might add even more electrical stuff in the future, here's a few threads on installation logistics, battery types, uses, etc.
