|Rockford Fosgate Power 1000 Mosfet|
Those who know car audio from the 80's and 90's know the Rockford Fosgate Power 1000 Mosfet. A beast of a four-channel amp, costing close to $3000. The model shown above is a later generation "Terminator Edition". First gen models were 6" longer with a caboose to help hide the wiring and they also had no LED meter like the later "Terminator Edition" and 1000c models. Understand, not all chrome Power 1000's with LED's are Terminator Editions. Internally, they appear to be the same amp, yet Rockford Fosgate gave appreciation to Wayne Harris' design of the shortened 1000 with the LED meters and made a limited run of Terminator Editions. Read the earlier article about this amp here.
While working on the full Amp Dyno test of the Power 1000, I thought the results were interesting enough to post a short video showing the 2 ohm bridged output using the Dynamic RMS Power mode. This mode adheres to the IHF-202 standard for testing dynamic power
Here are the results from my test with the SMD/D'Amore Engineering AD-1 Amp Dyno:
8 ohms mono = 4 ohms stereo x 2 8 ohms - Amp is rated at 200W at 12V (or 100W x 2 at 4 ohms)
8 ohms - Certified 1% THD - 258W at 12.85V
8 ohms - Uncertified - 262W at 12.87V
8 ohms - Dynamic RMS - 262W at 12.83V
4 ohms mono = 2 ohms stereo x 2 4 ohms - Amp is rated 400W at 12V (or 200W x 2 at 2 ohms)
4 ohms - Certified 1% THD - 421W at 12.53V
4 ohms - Uncertified - 423W at 12.51V
4 ohms - Dynamic RMS - 459W at 12.93V
2 ohms mono = 1 ohm stereo x 2 2 ohms - Amp is not rated at 2 ohms mono or 1 ohm stereo
2 ohms - Certified 1% THD - 573W at 13.06V
2 ohms - Uncertified - 856W at 11.87V
2 ohms - Dynamic RMS - 890W at 12.97V
All tests above were at 40Hz. We re-ran the tests at 1kHz and the only notable differentiation in results was the 2 ohms Dynamic RMS test where we obtained 920W at 12.79V. We have determined the difference was related to voltage and believe provided the proper voltage (14.4V), the amp would have measured over 1000W Dynamic RMS at 40Hz also. Not bad from a 200W amp!
