STINGER
A 6.5" coaxial car speaker with built-in multi-colour RGB lighting, 75W RMS power handling and marine-grade element-resistant construction
The STINGER SEA65RGBS is a 6.5" coaxial car speaker built for drivers who want coloured lighting inside the door panel. A wireless remote lets you switch between multiple RGB modes without extra wiring. Element-resistant, marine-grade construction suits open-top or off-road vehicles exposed to spray and salt. Buyers needing a pure audio upgrade without any lighting feature should look elsewhere.
The 75W RMS and 150W peak ratings show how much continuous and short-term power the voice coil can absorb before overheating. A polycarbon cone with resin-coated cloth surround and an oversized 1 KSV voice coil dissipate heat during extended high-volume playback. The built-in crossover keeps the pie dome tweeter from drawing low-frequency current that would raise coil temperature further. No active cooling or fan noise is present because the design is entirely passive.
The single specification that decides fitment is the 6.5 inch 4-ohm two-way design. The 65 mm cut-out must match the factory opening and the 4-ohm impedance must match the amplifier or head-unit output. If the vehicle uses a different mounting diameter or requires a 2-ohm or component-speaker layout, this model will not install correctly.

Connect the precision non-corrosive terminals to a 4-ohm stable amplifier, then run power to the RGB module for the wireless remote; the step most installers skip is fitting the supplied sealing gaskets to keep moisture out.
The resin-coated cloth surround and splash-resistant motor sealer resist UV, salt and fog, so the speaker itself rarely needs service; only the wireless remote battery will require occasional replacement.
The 75W RMS rating marks the continuous power the oversized 1 KSV voice coil and built-in crossover can dissipate without overheating; sustained output above that level will trigger thermal compression first.
