Has anyone flipped their sound bar so its forward of the sportbar?
Is it a hassle?

I have done. It is not a hassle to do. I'm 5'11" and I found it extremely annoying to the point I just got rid of the sound bar completely. It will literally be directly over your head once you flip it.

Can you hear your stereo any better, I run a Bikini/Windjammer/Duster configuration year long so I thought it be a good idea to have the speakers inside.

My main problem with the sound bar flip was how it sounded. With a speaker directly above my head it total ruined the stereo image of the song.

you can always stick an amp under your seat or in the lock-a-trunk ... then you can hear your music from anywhere, hehe. i found that running the center straps of the windjammer kind of loose helped the sound get through the top a little better. i also think i've seen windjammer screens instead of windows, if you have a safari top that could shield out any rain.

i dont know the measurements but you could look for a yj soundbar, mine is mounted on the front bars.
