There are a bunch of photos on my Facebook page....
preview popup won't load for me so hope this works.....

Our system is 2 trailers, linked via radio. Each has 1x MTH30, loaded with Fane Sovereign 12-500LF, and 1x Tannoy V8, powered from Sure 2x300w amp module and 300 watt 12-36v upconverter. Crossover board from XKitz splits bass off at 100Hz and highpasses at 50Hz. Powered from 12V 38Ah Yuasa gel cells, total weight 70Kg per trailer. Booms it out!

The only one they do, there are two boards in each amp pack, the first one splits the signal at 100Hz and the second highpasses the bass signal at 50Hz (and has an unused lowpass section).

My legs ache thinking about that sort of load!
Amlu and s45, your rigs are beautiful - always impresses me to see them in use, you've both struck a good balance of practicality and size
Hopefully I'll be buying a tricycle this weekend, should have a bike system ready just in time for winter! :[
