Marine speakers 6.5 inch 160 W peak
The Sony XS MP1621 are a pair of white 2-way marine speakers built for open-water environments. Each unit handles 70 watts RMS and 160 watts peak power at 4 ohms impedance. An IPx5 water-resistant rating plus UV and saltwater resistance protect the polypropylene woofer and poly cone tweeter from splashes, rain and harsh marine conditions. A removable grille simplifies cleaning and maintenance.
Boats needing durable stereo sound
These speakers suit boat owners who want reliable stereo audio on deck or in the cabin and can accommodate a 4.914 inch cutout with 2.377 inch mounting depth. They are not for installations that require a different impedance, a larger cone diameter or a shallower mounting profile. Buyers needing built-in amplification or wireless connectivity should look at other solutions.
70 watts RMS power handling
The continuous 70 watts RMS rating is the key figure for matching these speakers to a marine amplifier or head unit. Pair them with an amp that delivers clean power near this level to avoid distortion or thermal damage. The 160 watt peak figure only reflects short-term bursts and should not drive the purchasing decision.

Questions about this item
How loud will the 160 W peak rating actually play on my boat?
The 160 W figure is peak power; continuous output is 70 W RMS, so plan your amplifier around 70 W per speaker for clean, sustained volume.
What does the CEA-2031 rating mean for the 4-ohm impedance?
CEA-2031 confirms the 4-ohm load and 70 W RMS are measured to a consistent industry standard, so any marine head unit or amp rated for 4 ohms will match correctly.
Will the 6.5" frame fit my existing 4.914" cut-outs?
Yes — the cutout diameter is 4.914", frame diameter is 6.512", and mounting depth is 2.377", so verify your hole matches 4.914" and you have at least 2.377" clearance behind it.
