Damn bro… to say your skill level has increased would be an understatement! Pretty soon you’re gonna be like Gordon the founder of Genesis, and building your own amplifiers lol

[@kubaz2308]

It's impressive how well you explain these so everyone can understand whats going On without a degree in electronics

[@joshholden8561]

I love those alpine type r subs i think they are 1 of the cleanest sounding subs ever

[@proluxelectronics7419]

It's a bit of a trade-off at high switching frequency, some mosfets will have a better stability at higher temperatures, like a sweet spot where gate capacitance "switching speed" become optimal for the drive frequency.

Congrats on 70k! Ive been watching your content for a while and its really helping me with getting my soundstream 6k back up and running, thank you and congratulations

[@theodoresignal]

Wow, amazing. Have you designed your own amp yet. Because I think a lot of people would buy. You are the man, bro.

[@kentaylor5842]

Amp repair in god mode.

[@jacktheripper1083]

Speechless, JUST speechless! Sam youre THEE man!!!

[@sedon7098]

Couple things. The thd on the irs topology is nearly unaffected by the death time. You just increase losses due to a higher conduction time for the low side fet diode and you decrease maximum power since the fets aren't on for as long. Also I would especially on the irs2094 increase dead time if there are no buffers since it does 0.5A max drive current compared to the 1A for the irs2092. Also overlap can cause huge ringing spikes when all the stray capacitances and inductances are literally plugged like a guitar string.

You are the Amp whisperer!

[@TheTimshady337]

I understand what you are saying and what you did to remedy the problem, but wrapping my brain around it all gave me a headache

[@bkrgls]

Great explanation! 👍🏽

[@justinvanburen8259]

Great work!!

[@mugendrewable]

Brilliant! 👏👏👏

[@n.shiina8798]

my fix would be find a better mosfet if possible lol. i guess having wider DT is okay for LF job esp for loud gangs but ehhh i prefer squeaky clean output. good job, though. your fix is way cheaper than sets of expensive mosfet

[@barevids]

For automotive environment the tiny increase in THD is negligible 😁 thanks!

[@rtronicslab1253]

Why didn't you post this kind of vids on KZbin....thats very helpful ....What was the music at the end...?

[@Wineman3383]

Cool video brother 😎✌️

[@felipehernandezhernandez5533]

Que excelente clase diste en un minimo de tiempo gracias , podras poner en algunos de tus videos sub titulos en español gracias saludos desde MEXICO

[@randomtube8226]

The end 🤣

[@Random_4400]

I will never understand some companies, a tiny amount of solder or 0 ohm links is cheaper than 2 resistors plus it would run cooler, absolutely doesn't make sense considering 99.9999% of companies try to SAVE money and want there product to be good lol Not to mention how big b2 audio is and how much reputation they have.

Build any frankenwoofers lately?

👍👍

Wow!!!

[@TS_sound]

Last 5 seconds of the video, legend mode: ON. That's a lot of info for 6 min video...I can only imagine how much it costs in real time while wondering da f is going on with this amp.

[@felisealoisio6107]

Have a question i got zx2500.1 kicker amp that has a strange proplem it turns on and play sound untill you volume up like said 10% out of 50% volume it flick protection mode for sec and keeps flicking untill i volume it down can you help please

[@smartorder4997]

Can you do a build quality review of Recoil Amplifier? They are class D and with unbelievable value.

[@joshholden8561]

There's already quite a few reviews of multiple recoil amps check out hifi vectors channel he has been making videos and dynos on recoil amps so has robot underground.

[@smartorder4997]

@@joshholden8561 i know but they are not at the view of PCB.

[@D1aNdOnLyNiCkx3]

@barevids can I send you an audiocontrol dm810 for repair? It's very very noisy and audiocontrol just ignores me

[@joejoemr420]

@barevids i have a question, i have a Brazilian amp same as the sfb 5k and i hooked it all up tuned it with a multimeter to 54v and it played awesome then went into protect so i turned off everything then turned back on came out of protect but the clipping light stays on and there is no output from amp, when i check it with the multimeter now it is saying that im getting 103v as the output what might cause this, thanks in advance

[@barevids]

Output circuit fault. Needs repair.

[@joejoemr420]

alright was worried about that, thank you for the quick response

[@smartorder4997]

Wonder would it be cheaper to buy a new one than the repair cost.

[@voca164e]

It is new though, so swapping out for another identical new amp would do nothing to alleviate the heat issue.

[@piti_rocks]

Was that that one from Germany?

[@barevids]

No

[@piti_rocks]

@@barevids you could have made fried eggs one my one back then 😂

[@str8upkickyaindanuts289]

It's amazing how so many amps are not optimized these days, I guess that's what happens when you don't design anything in house and rely on overseas build houses. Just add "designed in _____" and pretend we did it ourselves, in any other industry it's called con artistry.

[@sHoRtBuSseR]

See a lot of issues with B2 amplifiers honestly. Doesn't surprise me.

[@jayholm9623]

Amp is like 5 years old. Even though brand new. Most other issues are related to the introduction of fullbridge amps in our lineup. But they have sold in thousands

[@sHoRtBuSseR]

@@jayholm9623 B2 amps are some of my favorites, just growing pains for full bridge I suppose. I'm a die hard half bridge and a/b guy, I'm holding on as long as I can 😂

[@jayholm9623]

@dylanhouser2587 that's why the Rage 4500, zero9 and now the zero12 are there. Big powerful beasts. Also planning on a big 2.3k 4 ch and a 2.3k 2 ch

[@sHoRtBuSseR]

@@jayholm9623 I will see them at upcoming shows I'm sure!
