mdocod said:same way sony and pioneer and kenwood and all them cheapo china brands can build 5 watt amplifiers and advertise them as 100W per channel. because people will buy it because they are uninformed.
greenLED said:The same way other manufacturers do. That's why by principle you don't trust manufacturer's output numbers unless they've been verified independently (by us, of course).
EsthetiX said:Good point. i never bought anything by mag or inova. Anyway... yaaah All these manufacturers claims seem to be waaaay off.
cy said:.....seems they do rate output at source VS out the front end like surefire. what counts of course is what you get out the front end.....
Manzerick said:it's almost like the "EPA" gas mileage estimates. My car is rated 18c/28h yet I average 19 per gallon. This would seem normal but I do 95% highway driving which should equate to (28*.95)+ (18*.05)= 27.5 .... Even given loss and any "tuning" issues one could point a finger at this is way low...

Turbo DV8 said:I read that a rule of thumb to figure how much a car amplifier actually outputs cleanly is to halve the rating and then deduct another 10%. So, an amp rated at "Awesome 400 watts into four channels" (notice they don't say per channel) actually puts out 100 W/Ch less 50% = 50 W/Ch less 10% = maybe 45 W/Ch if you're lucky at a reasonable distortion level.
