Well I just looked at this thread, well 20 minutes ago really, fell off the chair and have been laughing ever since!
Those plates look just like the ceramic ones I see at the hardware store or the big Orange..
Amazing what people will believe or get tricked into believing.
Wow lets see guys, Recently,I have heard that putting a bigger fuse in your car stereo amp circuit makes it louder! As well as a chrome valve cover on your engine, thats good for another 40 horsepower and the chrome exhaust tip gives you +10 horse. Bet ya didn't know that! [Linked Image]

Buddy of mine threw a stereo in his 79' Impala some years back, bought good components, but used regular every day THHN, as speaker wire, regular 250V fuseholders and fuses for protection ( none of that gold plated crap here!) and ran some 2/0 welding cable in sealtight from the front battery to the back trunk where a sealed battery sat. System was just as good as some of these " profe$$ional" installs, only WAY cheaper.
