Two more pictures:

The back of the cab, with the amp connectors in the recess and the power connectors besides the battery compartment access.

 

Amp and battery options -

 

Top left: 90w per speaker Kenwood car amplifier

 

Top right: 7AHr battery with fuse and one way only plug

 

Middle right: Meanwell 12v 5A mains power supply.

 

Bottom left: 15w per speaker ebay amplifier for home practice or 'jamming with a friend' - work in progress.

 

Bottom right: 2.3AHr battery to power the smaller amp, giving a reduced weight rig for travelling - also a work in progress.

So is the idea a modular combo, allowing you to choose amplifiers and different power sources for different options?

 

If so I doff my cap to you sir, if not, I still doff my cap as it looks great.

 

I'm impressed,
