Car Stereo in Home AC/DC

I wish I had caught this thread earlier. Hopefully this will still help. I just built a second bench testing unit (pics later) that uses a Pyramid ps-52KX 45a continuous variable voltage power supply. They both run a 10a radio, 2 speakers, a 500w rms (@2 ohms) amp and subs. Both run 8-12 hours a day and are a fully functioning system. I bought the power supplies on ebay from sonic .for $230 shipped each. It is overkill but it is very capable and runs cool and solid. We all know electronics that run well under their rated loads thus running cooler will last longer than anything running near capacity and running hot.

I will post pictures this evening

(edit) here is a link to the build page I did for the first bench tester..
