While I at work about halfway through the night something occurred to me.... What if I were to hook up a voltage guage to my amp? Since it is a strapable amp I could just use the output side and connect the gauge wiring to the end of an RCA jack.. I'm not sure if it would work but it sure came to my interest. Would be cool to be able to tell what kind of voltage the RCAs were putting out and then put another one directly on the power to see how much voltage the charging system is (my car has no voltage meter)
