I just installed an inferno heater and it works great. Polaris does make a heater for them but the cost is much more and the reviews are mixed when comparing to the inferno. That's why I went with the inferno. great investment.
I believe it was a 42" light bar and I used the mounts that came with it. Yes I drilled holes through the roof for the mounts with a proper size drill bit for the size of the bolts so there is no play and things still stay as air tight as I can get them.
Sorry for the late response. For some reason I missed it. Yes it works with the speakers. Everything I have ordered from SuperATV has been designed to fit.
How much trouble are the upper doors to remove and install. A couple of times a year? The old style polaris uppers are such a pain to install and remove
You don't uninstall them once installed. They have zipper windows which I was a little skeptic from with my last machine and purchasing the kemimoto ones. These Polaris ones don't even belong in the same category as the kemimoto ones. They are built awesome and I have been super impressed.
