How Much Power Does a $49 4000W Walmart Amp Make? [4K]

[@revel8or]

There was a time when Blaupunkt was available only at exclusive retailers. They made a set of honeycomb flat speakers that cost a mint back in the day - but their sound was incredible. These guys and Soundstream, whose amps were all USA made…now manufactured to a spec that only WalMart would attempt to sell.

[@TexRobNC]

While true, I also remember when Blaupunkt started selling in Wal-Mart in the 90s, so it's been a LONG time

[@xtlm]

At least they are at Walmart level...and not something like Wish level yet. I guess.

[@drewdoestrucks]

The old school blaupunkt was made in Germany if I’m not mistaken. I don’t recall their stuff made in the us.

@@drewdoestrucks Blaupunkt was German. The company hasn't existed since 2016. Only the name remains.

[@revel8or]

@@drewdoestrucks You are correct. Blaupunkt was German, Soundstream was USA. Sorry about my ill-written comment as it logically says they were both USA made, when they were obviously not.

[@vincentrobinette1507]

Granted, it's nowhere near its rated power, but, if I spent ~$50.00 for this amp, I would be quite happy with it. That harmonic might be a high frequency superimposed on the audio signal. No problem, subwoofers have enough inductance to ignore that. If you're using this as a 'full range' amplifier, that high frequency could damage tweeters, especially piezo tweeters, unless they have resistors in series with them. That high frequency bleed through is likely the result of magnetic core saturation of the output inductor. That will only happen, at very low output impedance, where the output current exceeds the saturation current of that inductor. You're absolutely right, to look at the fuses. That is a "dead giveaway" as to the theoretical output power of the amplifier.

Thanks for the vid! I love tests like these. 8:13 and uncertified is literally how much wattage the channel can develop. You're just listening to unrecognizable noise at that point.

[@capn_shawn]

Those voltage pulses are simple to deal with. The reason for the pulses has to do with the switching speed of the power supply and the inductance of the input cables. You can't just remove energy from an inductor without it unloading the energy it has. This is how these amps make 60-90V rail voltage from 12VDC in the first place by switching on/off a large inductor inside to create voltage pulses that are stored as rail voltage. Problem is that the switching supply instantly turning off the power on the DC input cable makes the inductance of the DC cable do the same thing that the inductance of the power supplies is doing... making voltage pulses. Mind you, the inductance of the cables is orders of magnitude smaller than the internal inductors... but still. A good amp amp would have a place for that stored energy to go or would (more likely) alternate the internal charging between two or more inductors so that the 12 volt cable didn't see the sudden current shut-off during peak current demands. At least one of low enough frequency to matter. Adding a couple good quality film caps (of proper voltage and pulse current capabilities) across the 12V input should fix it and looping the power supply cables through a ferrite core will keep it from propagating down the cable and radiating.

[@marcr6749]

Agreed, good power for 50 bucks! I noticed the circuit board looked like the circuitry was split in half like they use the same board layout for a stereo amp. I wonder if they just internally bridged it and called it a mono block. The Chinese dont waste engineering on cheap electronics. It wouldn't surprise me if they want twice the amount of money for the stereo version but it is essentially the same amp unbridged with an additional speaker connector.

Way back in the 90’s this brand was used in some European cars like BMW and Mercedes Benz etc. And it’s quite expensive ($300-$500) on the market. So you will not be surprised if the windows of your bimmer are smashed the next day because you parked it on the side of the road.

[@pqrstzxerty1296]

It be 4000W outrut at DIN at 1Khz Peak to Peak. So basically it be a 500W rms at 8ohm, but I bet it be at 10K bandwidth, meaning say 2khz to 12Khz audio freq range, and not 20 to 20Khz. so I bet its maximum at 8 ohm is 75% volume is 75W rms 20hz to 20Khz, and a 100% volume 100W rms distorted.

Blaupunkt GmbH was a German manufacturer of mostly car audio equipment. It was owned by Robert Bosch GmbH from 1933 until 1 March 2009, when it was sold to Aurelius AG of Germany. It filed for bankruptcy in late 2015 with liquidation proceedings completed in early 2016. The brand is now managed by GIP Development SARL of Luxembourg and is used on various product groups worldwide. All production was outsourced to China after the takeover. However, Robert Bosch Car Multimedia GmbH still manufactures mobile audio products for OEM integration and not retail sale branded electronics. That company is under the Bosch lane and is not to be confused with Blaupunkt. *All cut n paste like info from Wikipedia.

I had a tube radio chassis back in the 70s from out of a huge old wooden 60s German Blauplunkt entertainment console and it was gold. The tuner was dead on and the amp unit drove a pair of Jenson 6x9 co axial speakers in boxes perfectly for what I wanted. Hey, I was a dope smoking long haired hippie kid who just wanted an FM stereo radio I could listen to while stoned. FM radio was good back then.

[@klocke5247]

So, sometimes they get these wattage figures by pulse testing the amp for milliseconds, before some kind of current limiting is used to keep the amp from melting into a solid block of plastic. It's not going to pass 32a for long. Hence the term "continuous" which means it can deliver the rated power all day long. If no time duration is specified, they're not technically cheating, are they?

Hi Derick. I am from South Africa, I like your channel and watch lots of videos. You are doing a great job. I see you test all kinds of amps and sometimes speakers. In this part of the world , manufacturers like Star sound , Targa , Ice power ect is quite popular. Did you test some of those or do you have some videos of those? i am running a very small audio system , using 1>< 12" Targa and a starsound mono block. The sub is rated at 4000w and the amp at 2000w , which i strongly doubt will ever push that type of power. What is your feeling toward these type of audio? I believe I could have done better with a 12" pioneer.
