@joeymt33 are you running a dual battery set up?
Im pretty impressed with my big amazon bar. i hit about a 4" thick branch doing about 40mph and all it did was tweek my mounting brackets and leave some bark in the tiny bolts. now that i need a new bumper..... im probably going to put a small bar in it to come on with the high beams. i dont get to use my big bar hardly at all since it blinds people in front of me, guess that might be why ive never noticed a voltage drop.
I use a dual battery setup but it will only do so much. The wetsounds bar and sub consumes a lot of watts then add in the 240watt lights bar with the 4 cubes also burning and I would see voltage drop to ~12.5. Most of last week I didn’t use the light bar. I can run all the lights if I don’t use the stereo. If the stereo is on then I can’t use that giant light bar. So my hopes are running five small lights upfront which will be less wattage but I can properly aim all the little lights and hopefully get a positive outcome. Another important note is they will be on two different circuits in case something happens I won’t loose all the lights. During one of the creek rides the four pods that I had on the front went out so I switched over to the light bar. That was a very nice feature to have those on two different circuits and it will remain that way.
As far as the strength of those light bars that you had mentioned, I don’t know if you noticed or not but when I climbed on top of my vehicle when you were taking our picture, I was standing on the light bar to climb up and down!
