Likely you could get away with replacing just the midbass drivers. In each speaker as that’s probably what blew. 

The Rev's should come out of the cans, so you won't need new clamps, just the new speakers.  Of course if you go to 10's I think you will need new cans and everything.

We have a 2016 malibu wakesetter 23LSV. After tower speaker trouble last year we were told that all 4 of our REV8 tower speakers were blown. The price from the Malibu dealer to replace is $3900. We have a G3 tower and I am looking to purchase REV8s online to replace the speakers. What type of clamp do I need for a G3 tower? Fixed or coming. Trying to get the cost down. We have also considered replacing with 2 REV10s (going down to 2 tower speakers from 4). Suggestions? 

We dropped off our boat yesterday at Tommy’s in Rancho Cordova.  Business as usual,  and our boat is scheduled to be ready next week.

Interesting thing. The Malibu dealer finder has Tommy’s back up for the Nor Cal dealers.  Maybe they worked something out. 

Nicely done, thanks. I wish I had found the injector link before I did all the chasing around.  I had to ream the manifold to install the ones I found at RC Racing.
