JBL Stadium UB4000 Powersports is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Just a speaker. I purchased this item because it appeared to be slightly less-featured and thus slightly less expensive than the UB4100. Even the people at JBL did not know the differences when I called them to ask the differences. These two products however are NOT to be confused as similar even though they are virtually identical in appearance. The UB4000 does NOT have blue tooth and is NOT an independently powered speaker as is the UB4100. The UB4000 is a simply a wired speaker bar and requires a head unit/amp to power it. If you are adding an easy sound system to your UTV or boat, I recommend you look at the UB4100 and avoid this model.

Good evening, buy the JBL 4000 bar and I would like to know what kind of power I should install. What impedance does these speakers support? Thank you very much for your reply. PABLO

Asked by: Pablo73
Hi! You will be connecting the soundbars to the car's +12V battery for power. While the impedance will be 4 ohms.
