My brother and me built a bike-trailer for taking our music nearly everywhere. We took apart a pair of old yamaha speakers and a car subwoofer and constructed a chassis made of formwork panels which are normally used for making concrete molds. It's quite heavy but this also means it doesn't move a millimeter when played at high volumes.

some details
hi xrk971, glad you like it! I attached some pics with details.
We are using a Hifonics Zeus amp Type Zxi 4404, rated 4x75 watts. It powers the two high-/midrange speakers and the sub (two bridged channels).
The panels we used are called doka 3-so, they are very widespread here in europe. i'm sure you have similar panels in us. its plywood made of three layers, glued and clamped together and coated with a robust layer of paint.

Thank you all! The space is just a storage for the cables and some other stuff. Under the base panel we built another box which is open on the back side. The sub enclosure is built as a bass reflex system and has its port in the base panel which leads the soundwaves to the back, where the high/midrange speakers are mounted.
When driving, we can store the tripods in that bass box.
BTW: The battery has 52Ah and powers the system for about 3 hours at 2/3 volume. And the power is really awesome.
Sorry for my english, i hope you can understand what i mean.

@chrisb: indeed we have a (also diy) cargo-bike for beer but we put our meat over wood and coal
@xrk971: not sure about this. we put the thing together and didn't know how it will sound when it's finished. i know that's not the best way, but we had no experience in designing sound systems. so i think we had a good mix between luck and sense. and in the meantime we had some real audiophile listeners giving us great feedback. the best thing is, that it really sounds great also on low and mid volumes.
for your questions: is there a way finding these values without exepnsive meters?
@zacster: that should work for the led-lighting
