I have a 2015 RZ4 with alpha z tower. it came with a pair of rev 10s and I added a pair of rev 8s this past weekend and the port side both speakers sounds great but on the starboard side there is only sounds coming from the horns?? Can someone help with this?? Hopefully a wiring issue at the amp or something. The tower was pre-wired for the speakers and led rings. Thanks in advance for any help. We are heading out this weekend and would like to get it all squared away!!
