My car was built with the upgrade Pioneer sound system that sounds great.
The dealer simply sold the car to me and took my traded-in old Pontiac. They installed nothing.
It is an American Chevy Cobalt not a Jap Prius.

Advertisers lie about amplifier and speaker power. Only continuous RMS power at low distortion from 20Hz to 20kHz is real.
Peak power or maximum power is simply double the real RMS power.
10% of horrible-sounding distortion at only 1kHz is usually spec'd to make the power number much higher.
Music power is a joke about how quickly the power supply sags. For the first couple of milli-seconds the power is much higher before the voltage sags.

 

guys..lets not walk into canadian/yanks/brits/azs/ chinese/ or "nations" made or this sort of discussions...this is not professional..

there is a clear note, and experienced folks are agree, >100W pure power is more than enough to destroy more "market available" speakers....if you still think that there is >500 pure WATTS market made amps, read this design. http://www.sound.westhost.com/project117.htm Hope after this understanding of power ratings will change significantly.

Actually, my point of sharing the results was different....

 

Nobody has made the 1500W amplifier. There is a forum about how many of them have blown up.

 

The intention is to clear the power rating perceptions by designing and showing what to expect.

 

Wow, you guys take April fools day serious.....
