Sale Price:


The Skar Audio SK8MB 2-way, 8-inch, marine full-range coaxial speaker system is perfect for upgrading the sound in your boat, UTV, 4-wheeler, or motorcycle. Sold as a pair, these 8" marine speakers are capable of some serious power output, with a conservative max power rating of 500 watts for the pair. This means everyone out on the water or trails will hear you coming from a distance, with extreme sound clarity. Not only do these speakers get loud and sound excellent while doing so, they are also built to withstand the harshest of marine environments. If you are looking for marine speakers that will withstand the test of time, look no further, the SK8MBs are exactly what you need.
The SK8MB features a unique and seamless 2-way design - in which the highly efficient silk dome, marine grade tweeter, sits atop the mid-range speaker, for perfectly balanced and clear sound reproduction. Furthermore, the marine housing that encompasses this two way design not only serves to better protect the speakers, but also allows the mid-range portion of the speaker to develop more accurate and dynamic, full-range sound. Sold as a pair.

    I installed these 2 8’s along with 4 6.5’s. They add the perfect amount of bass to seem like the boat has a sub along with great mid range as well. You won’t be disappointed
