let's see, about 700 watts, let's assume 75% efficience (PPI is pretty good for efficiency) we're looking at 933 watts actual draw


Doug / others, how does this car stuff compare to home stereo equipment?

At home I use 2 x 300 watts (continuous rms into 8 ohms). These sit in a massive big amp (70 kilos; 150 lbs). At full load these draw up to 8 amps at 230V, which is about 1.8kW gross (AC). At 12v this would into unreal numbers.

For the empeg in the car I use a Rockford 240.4, which claims 30 wats rms into 4 channels.
At home I never ever drive anything at full load. Actually, the pre-amp limiter is set to 65dB (max is 92dB)
Why would we need hundreds of watts in a car? Or are we talking different watts?
