Hi all!
This video features the Punch 250X2 from the Power series!
The dyno results are very close to amplifiers like the Punch 225.2 or the Punch 500a2 !
This car audio amplifier is a legend and still performs well!
Watch the sound test with good speakers or headphones!
In this video i made a test according to the CEA-2006-490A standard.
This is a method where they test pro audio amps today.
Input signal is a burst of 8 cycles with 1kHz and then a pause of 24ms, that means every 32ms the burst repeats.
Thats 31,25 times per second! This is simulating a crest factor of 15dB.

Nice. I still have my power 150, 2 punch 40's, 1 punch 60, 1 punch 75, 1 rf 2.3, and 1 rf 2.6 amps. Just can't beat old fosgate power and sound. I have a lot of other brands stacked up as well. Expensive and cheap brands I've collected over the years. My oldest working radio is a 1946 Motorola. Took me a year to get the vibrator for it. And yes it's an original 6 volt

Thanks for testing this bad boy! I have 2 of these and 4 of the 250m's, ive always loved the grey powder coat on these models. Have you ever tested the 250m? Would love to see that! Thanks for the great channel and keep up the great work!

Thanks a lot! Yes, I tested the punch 250M , I had two of them. I tested it when i was just starting the channel, maybe I am going to redyno it again , I still have one laying around. Check my videos , its still online 👍 hope to get another thumb there 😂👋

Ah the amps with the old X-Cards. Years ago I had to make an X-card, etched the board with a Dremel rotary tool and razor blade as I had an amp I needed to sell and the cards cost as much or more than the amp was worth (it was missing when I got the amp), it was a small amp. Cool amps, but I honestly do not miss the X-Cards for setting crossover frequency. 😅

You cab run these amps in "Audiophile" mode with no Xcards inserted. 👌👍💯🇺🇲

Good eyes 👍 I think I had one channel phase inverted 🙈

Please try to find a n mtx ta2300 amp to test. Theres a reason..I have suspicion that its better. Yes really related circuitry..

@audiokeller1975 5 ай бұрын

I know about the 2300 but it’s too hard to find even a smaller oldschool MTX in my location 🥲

73.4A draw at 4 ohms mono? Isn’t this amp supposed to be fused at 60A?

@audiokeller1975 5 ай бұрын

That’s correct 👍 but a dc fuse of 60A will not trip at 73A. It takes some time. The manufacturer suggested 60A fuse because you listen to music, not sinus test tones. Amp draw with music is much much lower because music has a way higher crest factor . Crest factor of sinus is 3dB ( 1.414 ) and music goes from let’s say 6 to 20dB because Music is dynamically! Todays manufacturers don’t rate their amps continuously, they do it with dynamic bursts, 20 or 8ms or bandwidth limited pinknoise. Some of todays amps will just burn if protection circuit reacts too slow when testing with continuous signal. Check out the original birth sheets - you will see values of more than 70 Amps, sometimes less.

Do you repair amps? And can you test THD?

@audiokeller1975 5 ай бұрын

Sometimes I repair amps to get them running for a dyno or fix them for friends, but I don’t test THD
