Birth Sheets Are Useless?!?!

[sonic purity]

they are innacurate for the fact that they are actually tested at 4 ohms and the 2 and 1 ohm ratings are calculated based on the output of what it did at 4 ohms and the factors which produced it.

i dont believe this.

Its true, I just read the thread on Rockford that talks about this.

"but the Power Elite amps are tested using the old method and will be migrated to the new method so this can explain the large differences ... for instance the old method didn't really test amps into 2-ohm and 1-ohm loads. It just tested into 4-ohms and mathematically calculated power for the 2-ohm and 1-ohm ratings."

a year and a half later (almost) im sure they changed since the "old method"
