I mounted the amp in my sand rail running a couple of Boss marine 6x9s, it's been performing very well with plenty of exposure to moisture, sunlight and lots of vibration. The only thing that would make this amp any better would be if MTX produced it in the USA. The quality is definately there, it's simply not made here, and made in the USA would make it awesome!
