Multimedia!
We've got a pretty sweet media system in Master 'Splores. This includes a Sharp 24" Smart LED DVD 12v/24v TV on a full motion wall mounted bracket with retaining clip so it can fold away neatly and securely when not in use. This can connect to a mobile hotspot to allow access to Netflix, Prime Video etc, or when we're out of phone signal, we can watch movies directly from a USB stick/DVD when in the wilderness. Connected to the TV we have a 600W Stereo Amplifier with Bluetooth connectivity and 6x9 Pioneer Speakers for cinema quality surround sound.
It gets a bit more complicated...
The amplifier was stripped down and modified to be able to mount shallower in the wall without cables plugged into the rear of it. The 230v transformer was removed and the power switch on the front wired to the 12v supply instead. The 12v in, audio line in, and speaker output connections were all removed and hard wired to the main circuit board allowing the wiring to exit out the side of the unit.
Eh... and there's also 2 microphone inputs... For van karaoke...?
