Upholstery/speaker install issue

All they are is CPVC Plastic Pipe with the edge beveled. I am on the road right now, and when I get home latter this week I will take a photo of some that I took out of my boat and show you how they work. it is a pipe inside a pipe. CPVC is the white waste drain vent pipe used in homes. Yes, you may have to remove most of the skin to do it right. That plastic backer board is hard to get staples in my it can be done. The front bow area is made of fiberglass and it requires a pneumatic stapler. Turns out my pneumatic nail gun was also a pneumatic stapler.

Thanks, would love to see how this works.
When I said "the ring around the cloth", what I mean is I think piping. Don't have it so that would have to be made, and will never match color of course... Thinking of maybe installing them flushed, so they don't stick out, without the cloth. Would much rather have them out of sight though... I'll first wait for those pics I think.
Thanks again!

Sorry for the delay. I have been traveling and very busy. Being a evening entertainer of the ladies takes a lot of time.
I also stand corrected. Pete is correct, CPVC is typically used for Chemical Service. You will need PVC, white color, which is used as Drain and Waste Vents in homes. The pipe is cut and the outside edges are beveled. The skin is stapled into the outside ring and screws are run from the back into the backer board and into the PVC rings. The center pipe has the hose like material stapled to the outside of the ring with vinyl trim around it. little 90 degree angles hold them in place. The speaker mounts to the backer board.

My 2002 Sport Nautique has six speakers. Two are in the bow area and four are in the cabin. One of the four speakers are in the kick panel. Here are the THICKER two sets of rings that are used in the bow area. If you have bow speakers you will need 6" and 5" ID PVC. You will need to cut the outer and inter rings 1 and 3/4" long.

Here is a photo of all six speaker inserts.



When I did my Wet Sounds install last winter, I chose to remove the old 6" speakers and replace them with 6.5" speakers. You will find that 6" speakers, higher end, are no longer available in 6". If you go with Polk, JVC, Kicker, or Wet Sounds, they are all 6.5". For this reason I pulled out the tubes, pulled back the skins, removed 1/2" more foam and installed 6/5" rings coated in epoxy resin, several coats, and screwed in those rings from the back side and mounted the 6.5 speakers from the top side. By removing some more foam, the speakers are deeper in the padding making them easier to lean against.

The Clarion 6" Marine Speakers are obsolete. In my humble opinion. I have tons of photo's from my install that I have yet to finish sorting out , but I will look and see if I can show you an example of what I did. If you get to the kick panel, that one is tricky, but I can show you how to do it.

Making it look easy! Thx for sharing.

There is a lot of information on Planet Nautique on this subject. Being my boat was a 2002, I had to go back several years worth of post under sound system upgrades to find information that pertained to my application. I studied about two years before pulling the trigger and the saw trigger. Most of the post are concerning the newer boats and such. You have to dig deep.
