It has a decent Bose stereo, and I'm looking to make some upgrades for it in the near future. When I first bought the Tahoe, I noticed that the Bose system would drain the life out of the battery wayyyy quicker than I would have ever imagined when the truck is off and accessories on. So I decided to get a dual battery setup, I purchased the Painless 42101 isolator kit. The problem with this isolator kit is the stereo doesn't draw enough power to have the auxiliary battery kick in. So if I leave the truck on for more than 35 minutes, the starting battery still runs dead, and the isolator won't kick in the aux battery for starting. So what I think I need is some sort of battery selector switch inside the truck so I can select the aux battery when the car is off but the stereo/other electronics are running. This switch would need to work in tandem with the battery isolator so when the truck is running, both batteries can switch back and forth for charging.
