I made my first speaker/amp cabinet a while ago. It's 3/4" Birch plywood. I had an old Behringer 212 amp that I salvaged the speakers, handle and feet from. I did a Fender style tolex wrap and a blonde Fender style tolex. I added some white piping. In my opinion it looks kinda like a mix between a Fender and a Marshall cab. It's a backported design with two 12" Jensen speakers. The speakers were the only decent part of that old Behringer amp. I got a pre-wired jack plate off eBay that let me do different impedances depending on which head I use. I can run both speakers in Stereo 8ohms with two different amps going into it, or just run one speaker direct at 8ohms, in parallel at 4ohms, or series at 16ohms.
