If you need a Review before you buy, then either call the shops that are selling them Check out YouTube there are some reviews there. Or check out the SidebySide fourms the UTV' fourms I would bet more people on thoes fourms would have experience with them.
We are gonna get one but not sure when. As far as wetsounds go they make quality products so not worryed about being let down. I have been using my JBL pulse so I'm sure the Stealth 10 is gonna sound ton's better
