The Boss AR4000D is advertised to deliver "4000 Watts MAX" at a cost of around 100 US dollars. Most people who know car audio and ratings know this is a bloated rating. Many people want to know what is the true, RMS power rating of this amplifier? Well, let's take a look at the amp, hook it up to a subwoofer and try it out on the Amp Dyno.
