Mounting your Polk Audio DB572 marine speakers involves either a flush mount or surface mount approach. Here's how to do it:
Flush Mount Installation:
- Mark the center of where you want to mount the tweeter and use a hole saw, drill bit, or razor knife to cut a 2" (50.8mm) diameter hole.
- Assemble the flush mount cup, clamp, and the provided machine screws loosely.
- Run the speaker wires through the round opening at the bottom of the cup.
- Insert the assembly into the 2" (50.8mm) hole until the clamp edge is below the mounting surface. Then, tighten the screws. You can bend the clamp legs outward by inserting a screwdriver through the cup's holes while it's mounted.
- Connect the wires from the tweeter terminals of the crossover to the tweeter itself using the faston connectors. Match the red wire from the (+) terminal of the crossover tweeter output to the red (+) wire on the tweeter.
- Secure the tweeter by snapping it into the mounting cup.
Surface Mount Installation:
- Using the base of the surface mount cup as a template, mark the screw hole locations and drill them using a 1/8" (3mm) drill bit. Drill a second hole (for the speaker wire) using a 3/16" (5mm) drill bit.
- Attach the surface mount cup to the panel.
- Feed the tweeter wires through the open area at the bottom of the cup and through the 3/16" (5mm) hole in the panel.
- Connect the wires from the tweeter terminals of the crossover to the tweeter wires using faston connectors. Ensure you connect the red wire from the tweeter to the (+) terminal of the crossover tweeter output.
- Mount the tweeter by snapping it into the mounting cup.
