I had a set of old Apple desktop speakers kicking around, which I've mounted at each end of the dashboard and wired in parallel with the front door speakers. This vastly improves the clarity of your tunes when trucking along with 2.5 litres of noisy diesel engine beside you in the cabin.

But! There's a twist...! I installed 1/4" jack sockets in the pillars and the speakers are removable - with a couple of extension cables I can take Pink Floyd with me to the camp fire up to 10 metres away.

A couple of very discreet switches below the door speakers lets me switch them off so those sleeping in the van aren't disturbed while I chill out to Dark Side of the Moon outside.

Thinking I might build a couple of sturdier outdoor speakers now...
