For music on the go
Whether cruising through waves, sand, or mud — you want to hear your tunes clearly over the noise of having fun. MB Quart's NA3-1000.5 marine amplifier can send four speakers 60 watts RMS each and a subwoofer up to 350 watts RMS, which'll keep the music rockin' no matter where you are. This rugged and compact amplifier utilizes a number of technologies that ensure normal operation no matter what the conditions are — like over/under voltage protection, thermal slow-down (not shut-down), and current limiting on the outputs to protect speakers.
Versatile amp
You can configure this amplifier as a 3-channel amp and send 240 watts RMS each to a pair of high-performance tower speakers, for example, plus 350 watts to a sub. The onboard variable tone controls let you tailor the sound to match your particular speakers and subs.
Marine-tough
Three decades of marine and powersports audio expertise goes into making each MB Quart marine amplifier. Conformal coating protects the internal circuits from water and dirt, while stainless steel hardware resists corrosion in even the saltiest environments. MB Quart designed and tested this amp to stand up to the toughest conditions on the water and off the beaten path.

Bought this monitor and returned it the same day because although I have an Nvidia GTX 560 video card, it was not powerful enough to scale resolution up to 4k HD. With the video card I have I was unable to go higher than 1080p !! So, before you buy this monitor, please sure you have the right video card with HDMI 2.0 and/or a Display port.
