Rockford Fosgate Punch 45 HD car audio amplifier dyno power test & repair

Audiokeller 2025-09-12 | This power test video features the Punch 45 HD made by Rockford Fosgate in the early 90s.
Thanks to Ulli's support i was able to dyno test this little old school car audio amplifier after the repair !
It came in defective but the fix was easy because these amps often feature well known problems after all the years!

Kenwood KAC 1023 car audio oldschool stereo amplifier output power test ampdyno 1 Ohm

Audiokeller 2025-07-25 | This subscriber supported video features an old school car audio amplifier made by Kenwood in the early nineties.
The amp came in defective , one channel had no output. Luckily all transistors checked ok.
The problem was a relay with damaged output contacts and an open trace on the RCA ground. I repaired the amp and now you can enjoy the amp dyno video :)
After the repair i dyno tested the amplifier with 50Hz and 1kHz continuous sinewave input signals.
I also tested for dynamic power with 3 different input burst signals: 20ms 1kHz burst regarding IHF 202 standard, 8ms burst 1 kHz every 32 mili seconds and a very short 1 ms 1 kHz burst test which represents the maximum peak RMS output power of the amplifier for a short time.

I also show the difference in power consumption between continuous test signals and burst signal. The burst signals have a higher crest factor than continuous sinwave which has a crest factor of 3 dB. High crest factor signals have less demand to the amps power supply.

The amp is nicely underrated and it was impressive output power. I was also very impressed of the build quality of this Kenwood KAC 1023 ! It was a pleasure to work on such a device !!

Fosi Audio BT20A mini amplifier power test , sound demo , review

Audiokeller 2025-05-18 | I got this little amplifier from a nice supporter to do a dyno run and sound test.
This amp is really small and delivers a nice amount of output power ideal as a desktop amplifier.
Its a class D design and has a good protection against overload or low impedances. Its also possible that it shut off because of power supply limits ;-)
All tests are continuous power tests because the amp doesnt have dynamic headroom.

This amp is rated 500 Watts into 4 Ohms, 1000 Watts into 2 Ohms and 1500 Watts into 1 Ohm.
I bet it will deliver more output power if tested with 14.4V and up!
All tests made with a 50Hz sinewave signal.

Crown XLS 5000 watt pro audio amplifier repair amp dyno & detailed output power test clip behaviour

Audiokeller 2025-03-23 | This video features a powerful 5000 watts pro audio amplifier - the crown XLS 5000.
This amp is almost identical to the Phonic XP 5000 and QSC RMX 5050 but with less features.
It features just a built in clip limiter , xlr inputs, binding posts and speakon outputs for the speakers.
No dip-switches for low or high pass filters.
This amp should do a good job on bass or subwoofers.
The crown xls 5000 has been tested into several resistive loads like
8 ohms, 4 ohms and 2 ohms per channel with continuous sinewave and several dynamic burst test signals - 50Hz and 1kHz.
I also demonstrate clip behaviour and the difference in output power between both channels driven and a single channel driven.
The amp had a shorted transformer , a damaged power switch , soft start board had wrong components soldered in by someone who tried to fix it previously and some resistors were damaged which made bias adjustment impossible. Now everything is fixed and the amp is ready for the dyno test 👍😊

1997 Rockford Fosgate Punch 200.2 oldschool stereo amplifier power test low ohm amp dyno

Audiokeller 2025-03-09 | This video features a nice example of an oldschool Rockford Fosgate punch amplifier from 1997.
It performed very well especially in the low impedance tests.
Ususally most amps i tested were able to do some dynamic burst output power into 1 Ohm per channel but this model was able to put out even continuous sinewave power into 1 Ohm per channel!
Dynamic burst tests were made into 0.5 Ohm per channel which was also very impressive.
Continuous tests were made with 1000Hz and 50Hz.
The amp wasnt as underrated as other amps i tested so far from Rockford but this amplifier really surprised me with its performance!

The t.amp TA 1400 pro audio amplifier ampdyno continuous & burst output power test review & overview

Audiokeller 2025-01-07 | In this video i present an output power test of a 20 year old pro audio amp which was a nice budget amplifier. The amplifier is still available with a different model name: " T.amp TA 1400 MK X ".
In this dyno video i also show the clipping behavior of the amp with a scope!
The dyno features continuous power tests with 1kHz and 50Hz into 8 and 4 Ohm resistive loads and also dynamic burst tests with 1kHz and 50Hz which represents a simulated crest factor and is more like " music power ".
The amp was famous for its low price and high output power, especially for DJs or bands.
In the early 2000s this model range made high power sound reinforcement affordable.
I guess these t.amps were the most discussed amplifiers in european message boards because it was just unbelieveable that you really get an amp in this power range for under 300€ at this time.
I bought the bigger brother in 2002 and was also really surprised. It was the TA 2400 which delivered around 2x1200 Watts of 1kHz continuous power into 4 Ohms per channel! If i remember correct, i paid 298€ back then - what a bargain!
Even today the updated models are still available and the price of the TA 2400 is under 400€.
It is clear that you can not compare these amplifiers with more expensive amps which can easily handle 2 Ohm loads.

Alpine 3544 oldschool car audio amplifier sound demo and amp dyno output power test into 1 Ohm

Audiokeller 2025-01-03 | Here is the review , overview and output power dyno test of the Alpine 3544 oldschool car audio amplifier!
Continuos sinewave and burst tests done into 4 and 2 Ohms.
Power tests dynamically down to 1 Ohm per channel both channels driven.
This is a nice stereo car audio amp and i guess from early 90s, rated 120 Watts into 4 Ohms.
That amp had a nice amount of power for early 90s and i guess it was really expensive.

Audiokeller 2024-12-15 | This video features a MTX Thunder 2160 car audio amplifier.
The amp was built in 1994.
I bought this amp used and workingh and it didnt power up when it arrived. There was a problem with the power supply rectifier - all legs broke. It was very likey a problem with shipping!
I found out that this amp has been designed by the same Sir who designed some oldschool Rockford Fosgate amplifiers.
The amp has been tested with different sinewave signals for continuous and dynamic power.
