Driver side speaker blown. Need replacement
You can also use a single voice coil 4ohm midbass but you will lose some low end volume. If you use a midbass replacement with 4ohms and sensitivity of above 90db you can make up some of the power loss. Installation is simply use one pair of your sail panel wires instead of both pairs.
I carry some as well listed on my site if you want to look at some.
