There are lots of circuit simulation free demos out there that you could use....

Dunno how good your electronics is?

Hi-Fi is easy in theory but much harder in practice...I cut my teeth trying to build amps way back...even the best published circuits needed tweaking unless you bought the whole kit with a pcb. My Mullard 10w (wow!) design picked up the local taxis brilliantly and would 'motorboat' spectacularly!

I just googled and the first response was a build it yourself kit... dunno if this is any use.

Have fun

Just google the net, there is free software out there, you just have to (metaphorically) open your eyes!!!

A quick google search turned up this page which describes a nice fallback DIY crossover kit should you not wish to design your own.
