WOW!

The Rockford Fosgate M210S4 10" sub looks amazing installed. A cut out stencil would have been helpful since it was a new installation but the measurement specs were included. I have this single 10 inch connected to a high quality amp's bridged channel with 200 watts RMS output at 4 ohms, with dedicated low frequency inputs. The infinite baffle sound is very comfortable for everyone in the boat, not too thundery or anemically mellow. I did get a hint of vibration when the sound is way, way up during a song with huge synthesized base, so I'm not sure if that was because the cone action was actually able to hit the cover, or if amp's input sensitivity was a little too high causing a clip, or if the sound output was just rattling something else nearby. Regardless, it was minor and will be adjusted so am very pleased with this purchase. I also appreciate Sonic's pricing, shipping and warranty.

Marine Subs that Sound Great

Definitely built to withstand the marine environment and they produce that great Fosgate bass sound. Rated at 250 watts each RMS, I have two wired in parallel and crossed over at 90 HZ. They will go down to around 40 HZ in a small box. The stainless steel grills are thick and kick proof. The speakers also have a built in cover to protect them from water and sun. The speaker grills including the outer rings are larger then normal so be sure to measure and factor the grills in.
