Aquatic AV Bluetooth & USB Waterproof Marine Stereo AQ-MP5UBT

£300

www.aquaticav.com This unit has an identical body and dimensions to the simpler Aquatic AV device, but is more fully-featured. The screen, instead of a simple LCD, is full-colour, and as such menus and controls seem easier and more intuitive.

The internal drawer will just about fit an iPhone 6, and will charge and play back via USB – which means you can leave your device inside and control the music selection with it safely charging within. The sound, as above, was somewhat brash, with the mid-range especially thinsounding, of particular concern with classical music. That said, maybe there aren’t many powerboaters (the intended market for many of these) that will listen to classical while blasting along in a RIB.

This is a full-featured piece of kit that, as long as you have sufficient room to mount it, would give you some decent audio.
