Okay, so I've seen a lot of threads about putting car audio subwoofers into a bass cab. I'm not even remotely interested in that. What I'm wondering is, are the basic properties and principles the same? Or even close? I'm considering taking up car audio relatively hardcore (as it were). The thing is, I'd love to be able to build my own cabs someday. So basically, I'm wondering how the wiring, impedence, bracing, and everything else like that compares. Any takers?
