Donations to

I recently accidentally deleted several emails from my phone and found they were not put in the deleted folder, but deleted entirely. I had a couple of people inquire about donating items to OldSchoolStereo. I'm hoping you read the website and see this post and send me another email.

You can feel free to use the donate section of this website or contact me if you have amps, speakers, head units or other old school gear you want to donate. I will most likely sell many of the donated items to help pay for the website and test equipment. 

Thank you for your support!

Video Updates - Lanzar, Fosgate, Alpine and More!

I've uploaded several videos since the last blog post here on There are three videos about the Fosgate "Frequency Energizer" Model 201 processor. If anyone has any further details about these units, please contact me at oldschoolstereo[at] gmail dot com.

First up, see the Alpine 3342 11-band EQ / Sound Field Processor. Just a quick overview of the EQ and showing it in action!

Next up, see baby Lanzar Opti Drive Plus 50 amplifier. I've had several people request I show off how I test amplifiers for operation when they arrive at OldSchoolStereo's labs. This is not a power output test, rather a simple speaker test of each channel and bridged operation.

Next up, see the BIG Lanzar Opti Drive 50c "Ultra-High Current" amplifiers. You'll see an early 1994 blue model and a later 1996-1998 black model. I overview the connections and check the amplifier "guts" for differences between the models. In a future video, we'll also bench test each of these amps for power output. Do you think there will be a difference in the output at 1/2 ohm mono? It will be interesting to see...

Now, here's some vintage gear from Fosgate Electronics. Yes, I said Fosgate, not Rockford Fosgate. This means pre-1980, folks. The Frequency Energizer you'll see is from around 1973 and is the foundation for the Punch EQ circuit used in Fosgate and later Rockford Fosgate car audio amplifiers.

***Amp output tests coming soon...I've done tests on the Lanzar 50c and Orion XTR-2250. As soon as I get a chance to edit the videos, I'll have them online. Thanks for your patience!***
