Two Battries in truck

[GMC HD 4x4]

Ok which one do I hook the amp to? The dealer said one is for the plow and the other is for everything else. I think the one on the passanger side is for the plow. Any info..ideas? Thanks

Hmmm...

I wouldnt think that it would matter as long as they wired in paralell. Does the alternator charge them both at the same time? If it does...i dont think it matters.



(although it might be a good idea to get some advice from someone who has an amp )

If there is a battery isolater on one of the batterys, then that is the one that you should use, it will only discharge that battery and not the one that runs the truck, if there is no isolater, than install one, you should be able to get one and the install instructions from a stereo shop.,

i would hook it up to the remote positive terminal. the red box near the alternator. i believe the passenger side battery is for the plow.
