First part of this is converting an unused 500w computer power supply into a DC power supply for testing. So far I've split all of the 12v rails (there's 2, of 18A each), the 5v, 3.3v and Ground into their respective groupings. Jumped the green PWR_ON cable to a single ground wire so I can leave that all contained inside the unit (jumping the green wire allows the PSU to turn on without being attached to a motherboard). Next is to test fit some 5 way binding posts, and find some banana plugs capable of receiving 8g wire to make some power leads for connecting to amps. I'll be making some 12v jumpers to hook into the REM posts on amps. One end of the power leads will be banana plug to connect to the PSU, and the other end will be spade connections to the amp side. If this turns out well, I'll probably do another one with beefier 12v rails so I can power multiple amps at the same time, like a full system test bench. After that, I'll be looking for an old school oscilloscope to sit on my work bench, get a proper soldering iron instead of the crappy 18w handheld one I have now. Get better storage and organization for screws, spade and ring connections, tools etc. I'm planning on starting up a part time gig stocking amps, head units, etc and eventually offering installation and system sales services on weekends. I already make pretty decent money, this is just kind of a fun thing for me to do, make a bit of extra cash on the side and maybe turn it into something decent, eventually getting into pro audio installations for competitions and things like that, retail equipment as a reseller for some of the decent brands out there (not big box stuff like JBL, etc). I tend to focus on the SQ side of car audio, not so much the crazy bass head stuff. I might even try my hand at doing some of the Soundman Car Audio iPad dash kit installs, etc. I'd probably focus on specializing in Mustangs, at least to start with since I'm going to be fairly low key to begin with.
