Rockford Fosgate Power 1000c Amp Dyno Test

The Power 1000c or Power 1000 MOSFET was Rockford Fosgate's top of the line amplifier offering from approx. 1990-1994. Earlier models of the 1000 were available in black or custom colors via the Perfect Interface division. The 1000c is one beautiful amplifier! It's retail cost was $2699 USD and was rated to deliver 150x4 at 4 ohms or 500x2 at 4 ohms. See previous videos where we've discussed this amplifier more in detail.

Updates at OldSchoolStereo - January 2017

Sorry guys, it's been a minute since I've updated the OSS website. I spend most of my "free time" editing videos and sharing cool pics on Instagram. OSS has grown quite a bit in the last year and we are now over 22,000 YouTube subscribers, 12,500 Instagram followers, and 5000 plus likes on Facebook.

You may have noticed I have also tested more new amplifiers. I feel this is important and I will include as much historical information on the company as possible. My BigDWiz YouTube channel will continue to show OSS content as well as other audio, video, photography and technology related videos. Consider the Old School Stereo component will be a "show" on the BigDWiz channel. We put a lot of time and effort into our videos and feel adding newer technology as well to the channel will help us grow, and also introduce people to the vintage gear.

Thank you as always for supporting OSS, see the updated video list in the Video Section of our website. I've posted a few of the more popular recent videos below. More coming soon! Make sure you are subscribed on the BigDWiz YouTube channel for updates when new videos are released.

Linear Power 8002SW Amplifier Amplifier Dyno Test Old School AD-1

Early 90's Linear Power 8002SW 800W Mono Amplifier
The Linear Power 8002 was an 800 Watt single channel amplifier optimized for 8 and 4 ohm loads. It was available from 1991-1997 and sold at a MSRP of $1599. Unlike most of the mono amplifiers of today, this 8002 is capable of reproducing the entire 20Hz - 20kHz frequency range. 

We initially ran all of the tests using the 4 ohm power supply taps, which lowered rail voltage and increased current. Amp is less efficient in this mode and also produced less power. After a call with Linear Power, it was suggested I set the amp to the 8 ohm taps to run the 8 and 4 ohm Dyno tests. If you read the original Linear Power manual, they caution against running the amp in 8 ohm mode powering 4 ohm speakers. It is quite evident these amps are overbuilt and are more than capable of handling the additional load without breaking a sweat!

Linear Power 8002SW's Guts - TO-3 Transistors

Specifications according to the 1991 Car Stereo Review Directory (July/Aug 1991):

"1 channel. 800 W x 1. Features biwired output terminals for feedback loop, which keeps speaker wire DC resistance from reducing damping factor; defeatable subsonic filter; soft turn-on/off; fan cooling; metal shroud. FR 19-20,000 Hz. 17 x 3 x 9.5 in - $1,600" (CSR Jul/Aug 1991)

The Linear Power 8002 was also in a battle of "monster" amplifiers in the October 1991 Car Audio & Electronics magazine. Other challengers were the Rockford Fosgate Power 1000 Mosfet, Precision Power 2350DM, Orion GS500 and HiFonics Colossus VII...quite a group of large, powerful, Class AB amplifiers! Since the 8002SW is a mono amplifier, the tester used 2 of these amps in the comparison. It may or may not surprise you, but the Linear Power came out on top. Quite an impressive feat, considering the competition!

Watch the video and see the results obtained from this 20yr old car audio amplifier. Nothing short of spectacular!

Here are the results from my test with the SMD/D'Amore Engineering AD-1 Amp Dyno:

8 ohms mono8 ohms - Amp is rated at 800W at 12V
8 ohms - Certified 1% THD - 818W at 13.99V
8 ohms - Uncertified - 819W at 14.05V
8 ohms - Dynamic RMS - 1029W at 14.31V

4 ohms mono4 ohms - Amp is rated 800W at 12V
4 ohms - Certified 1% THD - 824W at 13.5V
4 ohms - Uncertified - 855W at 13.48V
4 ohms - Dynamic RMS - 1407W at 14.5V
4 ohms - Dynamic RMS - 1606W at 15.17V



All tests above were at 40Hz. As you can see by the results, this amp is well suited for subwoofers or mid-basses as it has a nice amount of dynamic headroom for those transient peaks.

Rockford Fosgate Power 1000 Mosfet Amp Dyno Test 2 Ohms Bridged Dynamic IHF-202 Certified

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

1993 Rockford Fosgate 200 DSM vs SMD AD-1 Amp Dyno - Impressive!

1993 Rockford Fosgate Punch 200 DSM Amplifier


The 1993 Rockford Fosgate Punch 200 DSM was one of the most well regarded amps of it's time. Here's a quote from a May/June 1993 Car Stereo Review test of the Punch 200 DSM, "In terms of design, construction, aesthetics, and sonic purity, Rockford's Punch 200 easily stands among the best power amplifiers on the market today...If you're driving your system with something else, chances are you're listening to something inferior." (Ken C. Pohlmann)

We knew based on the previous tests of the Punch 200 this amp was powerful and dynamic, however we were unaware of the hidden "dynamic power" within this amp. Back in 1993, this amplifier retailed for around $600 US and replaced a legend, the Punch 150HD. It was no small feat for Rockford engineers to create a superior amp to the tried and true Punch 150, but trust me...they were successful! 

Watch the video and see the results obtained from this 20yr old car audio amplifier. Nothing short of spectacular!

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!

Old School Mini Truck System Orion HCCA XTR Wow

1990 Mazda B2200 Custom Mini Truck "Fantastic Voyage"

Lowered mini trucks are the epitome of old school car audio. If you were into the car scene in the early to mid 1990's, you know these trucks. Lowered, crazy paint jobs, wire wheels and of course boomin' stereo systems! Here we have a demo of the 1990 Mazda B2200 nicknamed "Fantastic Voyage" owned by Jason Williams. What a true time machine! See the truck as it was created in the mid 1990's! Stereo is classic old school including:


  • Alpine CDM-7823 Head Unit
  • Alpine CHM-S600 6 disc CD Changer
  • Audio Control 3XS Electronic Crossover
  • (2) Orion 225 HCCA Digital Reference Amplifiers
  • (4) Orion XTR 15 DVC Ferrofluid Injected Subwoofers
  • (4) Soundstream SS 5.0 midranges
  • (2) Soundstream SS 1.0 tweeters
  • Sega Genesis Game system with optional CD-ROM drive
  • 4.3" Color TV


A very impressive facet of this truck is the fact the Orion 225 HCCA amplifiers are rated at 50 watts each. That's right, 25 watts per channel at 4 ohms. The 225 HCCA is an example of the classic "cheater" amp meaning it was capable of MUCH more power at lower ohm loads. The 225 sub amp for example, is loaded down to 1/2 ohm mono and putting out over 500 watts! I know, 500 watts is not much by today's standards, but watch to see what it can do with the ultra-efficient XTR 15 DVC subs!


100 Watt Old School System with Orion 225 HCCA Amps and (4) XTR 15" Subs


The 1990 Mazda B2200 sports a custom peach paint job that really makes is stand out in a crowd. The truck also has some original Dayton 15" wire wheels with the classic 195/50/15 Dunlop radials. The stance is lowered 3" via lowered control arms and sits nice and low, yet still able to traverse speed bumps without scraping. The rear has one leaf removed and air shocks.

1990's mini trucks often times used "themes" for their presentation. Another famous mini truck was "Ladie's Choice" which sported a convertible hard top and a bed full of PPI 2350DM amplifiers. These themes helped differentiate the trucks while also assisting in the displays. Jason's truck sports Care Bears as the interior theme and also displays a couple of his many magazine features. This 1990 Mazda had the center spread in the December 1995 Mini Truckin' magazine! The most impressive part is the truck is almost exactly as was back in 1995! A true time machine!!

Jason sends a personal thanks to William Wilson of Hickory, NC who actually built the truck back in 1994. He also did a great job of preserving the Mazda for 17 years until Jason decided he needed to put it back on the show scene! Great job with the truck, William!!


Back Side View of the 1990 Mazda B2200 Custom Mini Truck


Big thanks to Jason for the demo! If you are at a car show in the NC/SC/VA/TN area and see Jason's Mazda, make sure to stop by and chat with him and get a demo of this amazing system. It is impossible to capture the full experience via video, but we try our best here at OldSchoolStereo!!

See the full 10 minute plus video of Jason's truck and even get a demo of the 100 watt (yeah, right) sound system:

Old School Rockford Fosgate Punch Pro SPP-184 18" Subwoofers



What's up guys? I know there are some of you die hard Rockford Fosgate collectors out there and I'm hoping someone has a pair of the infamous "Punch Pro 18's" from the late 80's /early 90's. The model was SPP-184 and at the time, they were some of the biggest and baddest subs money could buy. I have a friend who's working on an old school install and these subs are essential pieces he's missing. 

Please contact me via Facebook if you have a MINT/NIB/VGC set of these subs. I'll make sure to get you some OldSchoolStereo.com stickers for your trouble and hopefully we can work out a reasonable price. 

Here are the specs of the SPP-184 as provided by Rockford Fosgate:


  • 18" Pro Subwoofer
  • 159oz Magnet
  • 3" Vented Voice Coil
  • Power Handling 200W continuous average
  • 4 ohms (SPP-184) single voice coil
  • Mounting Depth: 7 3/4"
  • Sensitivity: 94.5dB 1W/1M
  • Approx. years of mfg: 1987-1992
Rockford Fosgate Punch Pro SPP-124 12" subwoofers - same style as the needed SPP-184's

Tommy Clark's "Rockit Science" Ford Econoline Van 1989 IASCA Finals - Speaker Warehouse JL Audio PPI



Wow, I'm sure some of your old school guys recall this install in Car Audio & Electronics magazine back in the late 1980's...but thanks to YouTube user Manville Smith (not confirmed if this is THE Manville Smith, but once we have it confirmed, we'll update the page). It's something to see the install as pictures in a magazine, but the video just takes it to another level! The dedication to the details and the fine craftsmanship are second to none in this install! Enjoy the video!!
