I'm not sure if this is the right forum for asking this, but I always hear people talking about making their own cabs and installing speakers themselves and things like that... where do you learn to do these things? I've got a GK 210SBX with the speakers blown out that I was planning just to sell, but then I thought maybe I should try to install some new speakers. Are there books I could read, or some websites I could check out? I know I can take it to a shop or something and have them do it, but I'd really like to learn to do some of this stuff myself... if I can.
