Product identity
The Poly-Planar MA6500 is a 5.25-inch marine speaker built for boats and other wet environments. It uses a three-way design with a mylar tweeter and midrange mounted across the main cone. The colourfast plastic frame resists UV damage and the waterproof construction handles direct exposure. Stainless steel mounting hardware is included for installation.
Deciding specification
Peak power handling reaches 320 watts while continuous power is rated at 80 watts at 4 ohms impedance. The cutout diameter measures 121 millimetres and the mounting depth is 65 millimetres, so the available cavity space determines fit. The outside grill diameter is 160 millimetres and each unit weighs 3.00 pounds.
Fit and alternatives
This speaker suits owners replacing a single 5.25-inch round unit or adding one location where the cutout and depth match. Buyers needing a pair for stereo sound must order two individual units. Installations with a smaller cutout or shallower mounting depth cannot accommodate this model. Systems requiring a different impedance or power rating should consider other options.

Questions about this item
How loud will the 320-watt peak rating actually play on my boat?
The 320-watt peak figure is a short-term maximum; the continuous power handling is 80 watts, which determines realistic listening volume.
What does the 4-ohm impedance mean for my marine amplifier?
A 4-ohm load draws more current than 8-ohm speakers, so your amplifier must be stable at 4 ohms to deliver full power without overheating.
Will the 65-millimetre mounting depth fit behind my helm panel?
The speaker needs 65 millimetres of clearance behind the cutout; measure your panel depth to confirm it fits before cutting.
