Dear Sirs,
I read, but I cannot remember where, of a new standard procedure for assessing the max peak current delivery of a car audio power amp.
Foolishly I did not save the link, because I think that this is very important datum that can say how anamp can drive demanding loads (i.e. low impedance and sensitivity).
Moreover I think it would be very advisable that the same procedure should be adopted for evaluating any audio power amp.
Anyone has read that article ?
Thank you so much.
Kind regards,
beppe |

| It should be quite easy. Drive a square wave or impulse into the amp loaded up and compare output vs input. |

Dear Sir,
thank you very much for your kind and valuable reply.
As I said, I found very interesting that after having read how is important this value of the "max peak current" available from an amp someone has gone through the hassle to fix a standard procedure of measurements.
But I cannot find the link again.
Thank you very much again.
Kind regards,

Why not use the honest RMS ratings that decent amplifiers have used since before WWII? - why invent another confusing 'standard', no doubt simply because it gives inflated values compared with RMS?. |

| I see your point, but I think it's valid to look at impulse responses because they will tell you a short term dynamic response. Granted, with the 20kHz upper bandwith limit and steep roll-off above that of CD, and modern pop recordings, there is little dynamics, but it's still worth looking at IMO. |

CES 2006 is not that a tough rating as it is measured at 14.4v with 1% THD....
You will often see 10-20% less power at 12v. |
