Pyle
A pair of 8-inch waterproof marine speakers rated at 320W peak and 160W RMS for boats and off-road vehicles
The Pyle PLMRS8W supplies two 8-inch component speakers built for marine watercraft and off-road vehicles. Each unit uses a polypropylene woofer with a weather-resistant rubber surround and an aluminum voice coil on an 8 oz magnet. The engineered ABS frame and low-profile housing resist corrosion and fit standard OEM cut-outs.
The speakers present a 4-ohm load and handle 160 watts RMS with a 320-watt peak rating. Frequency response spans 40Hz to 18kHz for full-range stereo output. Amplifier gain must be set to match the RMS figure so the voice coil is not overdriven during extended high-volume use.
Verify the existing opening matches the 7.5-inch cut-out diameter and that at least .94 inches of clearance sits behind the mounting surface. The included 9.8 ft speaker wires reach most helm or dash locations. Buyers needing a different impedance, a separate tweeter mount or a non-white grille cannot use this kit.

The 160 watts RMS figure is the continuous power the speaker handles safely. The 320 watts peak rating only applies to brief musical peaks, so match your amplifier to the RMS value for reliable performance.
The 40Hz low end delivers audible bass for engine noise and music fundamentals, while the 18kHz high end covers cymbals and vocals. In open marine environments you will hear most instruments clearly, though sub-bass below 40Hz will not be reproduced.
The 4 ohm load is standard for marine and car amplifiers. Most marine head units and external amps are stable at 4 ohms, so you can connect the pair directly without wiring changes or impedance-matching devices.
