I cry when my amp fails...this guy grins and claps his hands!!

I've said it in the past, the biggest killer of amps is their owners. Clipped to death, frayed connections that allow stray copper strands in the amp, and poor electrical systems or connections.

The older Kicker KX2500.1 was indestructible.. Low voltage, clipping, excessive heat and it never gave up.

Skills bruv! I learn so much in each video, thanks heaps

Been missing your Vids my man ❤️ Work was busy just was no time 💎 but enjoying it again 💎🥂

@barevids nice work man. Crazy how simple JL amps can be to repair. Then, sometimes, they can be a nightmare. Those HD amps don’t like being clipped and ran hot. That’s how my old HD750.1 got fried. Friend of mine burnt up my amp. When the amp gets hot, it lowers its power and when it’s safe to run, it will give you peak power again. The little LED is a status light that changes color to let you know. Bet the owner ran the amp hot and kept turning up the knob till it couldn’t take it anymore. Love the new style of video work though. We need a live one day friend.

If the board has a lot of thermal mass from multiple layers of internal power and ground planes, use SRA / low melt solder to remove through hole components. They will literally fall out of the board very quickly using much less heat. I have to do this when working on any through hole components on modern computer motherboards, Xbox's , PS4s/PS5s, etc. The boards are just too thick and will suck up heat like a sponge, even with a powerful iron you will be there forever.

@pgmurray76

Exactly. I put a heat gun on low temp 5 inches away to evenly heat the board and lovely Pb lead solder to reduce the melting point. Flux is always helpful. RoHs THIS!

My take away is: don't buy JL. Thanks for your humor and great info.

Like this format good info thanks

JL is such a cool company. They are the only ones to this day that I know of that do their rated power, no matter what from 14.4 down to 11.5 at 1.5-4ohms. (Did the test in my car myself. Of course, I don’t do that daily. I usually don’t drop below 12.3 on my setup. I’ll do a walk around of my setup one day on my channel.) Which means, even on a stock electrical, it will do its power as efficient as a 3-5k with all the upgrades necessary to keep your current up, and voltage up. This is why I run JL in my car. Expensive, but I guess the cost of all of the alternator, runs of 0 ga, and batteries I would need to have, just to have the same output from a 3-5k, balances itself out. And, I can move them from car to car without having to buy all the listed above, just to have a 3-5k amp run safe and not stress the power supply of other amps. Those with Perry’s guide knows, that the 1000/1v1 amps have a potential of 300 plus peak to peak rail. Be careful with those JL amps. They are more powerful then you think.

There are a bunch that do their rated power now that SMD amp dyno exists. There are channels that do amp dyno runs and alot do more than rated. But the ones that do are specific. Look at the channel Williston Audio Labs. Im sure you will enjoy

@@coolstreetman thanks for the referral, but I know of all of the channels that do amp dynos. I’ve seen the 1st run of the dyno setups on Tony D’Amore channel, (designer and founder of the SMD dyno and tools) over 10 years ago. As for the amps doing their rated power, yes I know some of them do. Thing is, they require a lot of voltage at higher ohm loads. In other words, a 1200w at 4ohm amp, which most likely will be around 4500w amp at 1ohm or more depending on the components and amp design and type. Most wire their amps at low ohm loads. Which in return, require a high current to do rated power, where as JL doesn’t matter from a 1.5-4ohm load because it has a regulated power supply that controls the current which keeps the the power balanced across the ohm loads listed. Example, if I wire a 4 ohm sub to a JL amp (R.I.P.S. Line of amps Slash and HD amps) , it does it’s peak power 1,000/1,200w. If I wire a 1.5ohm sub, or a 2 ohm, or 3 ohm, it will do its peak power from 14.4-12.4v safely. If you get a 4,000w amp that is 4,000 at 1 ohm, if you wire it to 4 ohms, most you will see is 1,000w or a little bit over or less at 14.4 and when the voltage drops, so does your wattage. Downwards of 600-800w depending on your current and voltage. You won’t see 4,000 watts at 4 ohms. That’s the difference.

You are moving the goalposts. The other amps still do their rated power at whatever ohm load. It literally says in the amps advertising what the different ohm load rated power. 8,4,2,1. I'm an electrical engineer there is nothing special about how JL makes their amps. You are just a fan boy trying to sound smart. You think JL has some secret sauce on voltage stabilization? You really don't know what you are talking about. You are probably someone that thinks that apple products are inherently better because they cost a ton of money. There is no patent for circuit board designs so the JLs aren't special because even them are copying someone else's designs. Now if you want to talk about the build quality of JLs Subwoofers we can have a conversation because they make high quality subs.

I think you saw no switching because there was no resistance or anything between the BJT's output/gate input and the neg rail, i've seen similar behavior on other circuits i made myself and i was like "why aint it working" till i connected a 100k resistor even lol till it worked at all

Oh, and great work on the thumbnail 👍 I'd hazard a guess that your views from non-subs are up on the last few videos...?

You know your stuff! Wow! My question is: Take an amp that uses a DC/DC switching power supply, ok? Will the power output vary with the input voltage, or can the power supply compensate for the voltage change and still output rated power? Say range from 11.5-15 volts. Thanks

@barevids

2 жыл бұрын

Hey Curt! Typically, with SPS in car amps, power supply PWM duty cycle is fixed, so as the input voltage changes it directly affects the rail voltage generated at the rectifiers on the secondary, which will change the clip point of the amplifier so yes it directly affects power output. Quite a few amps have regulated power supplies that vary the duty cycle of the power supply mosfets, which can keep the rail voltage at a fixed level. Its essentially sandbagging at higher voltages to stay within power and voltage design limits of the output section.

This is 1 of my favorite kicker amps ever made wite them to .5 half ohm and they do stupid power.

Awesome vid bro!! Hey,I've got a jp33,and 4 10s in a vented box tuned to 32hz,the bass is fn great,but the amp is clipping and smidgen but sound awesome, not obvious indication of clipping other than the clip light, is it bad for the subs?

Why not just use a deep cell group 31 battery? Batteries replenish power internally, whereas caps need an external source to replenish. Ideally, one would want to have a huge capacitor bank using rail voltage. A external bank can kill someone, but that's where you'll get big reserves for power etc

Ive got an amp, that has a CLIP LED, That is always lit, when amp is powered on.... Amp READY green light, lights up as it should, But from the second i power it on, The CLIP light is dimly lit... Not lit brightly, Just dim..... and i have 7.7vDC at output terminal of that channel.... Other channel is function perfectly.. No DC offset at terminal.. CLIP light isnt lit etc... Any idea where to start? There are clearly no dead shorts, As amp powers up, Protection relays click and amp channel LED's go to READY.... Thanks

Were the dead caps Vishay? And were they X types which are supposed to be self healing and handle voltage spikes. I've never seen a film cap blown and I deal with valve amps with spikes of over 1KV, weird.

How easily will clipping cause death of caps? I was wondering with my SD8K 2Ohm evo2.1, can I set the gain to 126V at -5dB and have it clip at peaks, while obviously watching that voltage won't go under 12V? I only have a 160A alt, 6x40Ah AGMs but also 2000F of supercap banks. Re of the sub is 1.4Ohms, Imp rise at Fc should be 2.5Ohm and at 100Hz, 1.7Ohm. I have in the past come to the conclusion that -5dB sets a good volume level with not too much clipping at full volume, but the SD is a lot more powerful and sensitive than my earlier Korean amps. Also, while I set the gain, the fan comes on right with the clipping light. Does it also come on with temperature or just clipping?

@barevids

2 жыл бұрын

if the amp is clipping on the "kick" or impulse of the bass note only, and NOT on the tone/sine of the bass notes, then your LPF is TOO HIGH. For Brazilian amps, all of the knobs on the side should be at minimum, other than the gain. Then, an additional LPF should be set on the head unit or processor to around 55hz. You dont want a flashing clip light on the kicks, so if you do, reduce LPF until clipping comes on equally for kicks and tones throughout the track.

@@barevids I use a Helix DSP.2, where I can set all kinds of filters and slopes. I think I had the HPF at min and LPF at like 100-200hz on the SD and 100hz 12dB crossover on the DSP. Not at full power yet, just testing. Are you saying I should have a 12dB/oct filter from around 55hz and 24dB up from 80hz? I usually set the gains with a 50Hz .wav sine wave file. That would make the bass sound even less flat, It's a custom sundown nsv3 18 in a trunk wall tuned to 25Hz. The lows with that kind of filters would be overwhelmingly overpowering compared to the mids? I do have 12s with 500W each in the doors, but they can't keep up from 55hz that well. Or do Brazilian amps have such a roll off at the lows, that they don't get the same voltage than kicks? If so, what would be the best way to ensure constant voltage over the entire pass-band?

bro get some chip quik (or generic equivalent) low temp solder... you can then add low temp solder on there, little by little until you have replaced alot of the hard to melt lead free solder with extremely low temp solder.. obviously you do not want to keep the chip quik on there permanently and its damn expensive.. but it works and will keep you from burning up the board.

That makes it worse. You want to LIMIT the amount of power through the board. It would be better run on 10v not 15.6v. People think strong power supply means it will be better at low impedance. Strong yes, high voltage no. Maintain 10v no clipping most amps are good for 0.5ohm. 15.6v means so much more power can pass through the board before clipping it will overload the components even if its clean.
