The AW339 is a great addition to your spa/hot tub. We recommend one transducer for a small hot tub and two transducers for a large hot tub.

Here’s how to do it:

Step 1. Get to the underside of your hot tub.

Step 2. Decide where to put your transducers.

Step 3. Clear out any insulation so that you can reach the fiberglass wall.

Step 4. You may have to sand the fiberglass wall to make it flat and smooth. (CAUTION: if you sand down the fiberglass, wear proper breathing protection, eye protection and skin protection).

Step 5. Use a two-part slow-cure epoxy to attach the Unimount Brackets to the fiberglass wall.  The Unimount Brackets are included with the AW339s.

Step 6. Wait for the epoxy to fully cure.

Step 7.  Attach each AW339 to each Unimount Bracket.

Step 8. Wire the AW339s to your sound system and enjoy!
