well saturday i installed my second bat on the yukon. i mounted it in the rear passenger side up in the cubby hole (underneath) next to the leaf spring rear mounting bracket. i made the batt tray drilled some holes in the floor for the rods bolted it up wired it up my system loves this xtra juice.oh and put a brace on the tray nice and sturdy . i took pics i will put it in http://www.photobucket.com

okay fellas!!!! the way i have mine wired is as long as i am playing my system the isolator is active(both stereo batteries are together )for longer playing time . And when i turn my system off the main stereo batt under the hood will be cut off from the rear stereo batt so that they won`t drain each other over the 2 to 4 days that i don`t drive the yukon. ----- so you say i can still mix with the deep cycle? (basically their wired parallel)with the system on. :)

The SR200 is a "continuous duty solenoid" relay that is perfectly suited for dual battery setup. In the event of a failure some diode isolators will combine the batteries causing both to drain. If the SR200 fails the batteries remain seperated. If you are saying that it is not good for mixing different types of batteries such as a starter battery and gel battery that may be true. I don't know because I never checked. I have drained my deep cycle battery so many times I have lost count. My 136 amp stock alternator charges both batteries without a single problem. It runs a 1200 watt inverter and a 1000 microwave oven, and now I am adding my audio (small 500 watt rms) system. If I am missing something, please explain. I came here to learn.

^ True... with an Isolator you can combine/ mix and match any types of batteries and one has no effect on the other ;)

It will be cheaper for now to get another batt like it than to get 2 deep cycle batteries at once. i do value ya inputs :bow

did I ever post my paper on different battery types to the FAQ section?

I know it was on my site, but my site is down temporarily.
