Im interested if any one has a dual battery setup in their KK. id like to install a second one because of the cold start up days and I have a lot of electronics running when the car is off. and I am also doing a almost complete overhaul with the audio. the alternator is stock and If I am correct its the amco 250A version and for what im doing that should be enough.

I know that diesels almost always have a dual battery setup or more for their glow plugs.

I looked into it when I first got mine but didn't see anything. I ended up going with an Interstate MTP78DT. Fits right in with just a minor cable modification, gives you 1000 cranking amps.
