Has anyone added any audio upgrades to their GS450h. I was curious as to whether this would add to much drain on the electric/battery systems. I'm not talking about anything heavy, in my last GS I had a JL 12" with a JL 500/1 to add a little low end. Any thoughts?

 

You should post this in the general GS forum; very few eyes look at the Hybrid sub-forum.

 

i'm sure you could add an aftermarket system to the hybrid GS. like any audio system, you need to make sure you have a good battery and the alternator is capable. the regular battery is separate from the traction (hybrid) battery, so there shouldn't be any drain. but to be on the safe side, i would inquire with your service advisor and see if there's any impact on the electric/charging system, as well as discussing with your audio installer.
