Hey friend, thanks for advising people to protect their car audio tweeters in order to limit the low frequency bands. My home lab experience suggest that when you are soldering a capacitor, (4:29) the heat of the hot soldering iron tip under five (5) seconds will not damage the capacitor. But for soldering any other sensitive electronic components (such as diodes and other 'semiconductors') then one might needs a heat sink (and that does not need formal tools but can improvised by using almost any plyiers, such as the needle-nose ones, and rubber bands holding onto the handles.)
Your videos have been unbelievable. So much information and knowledge it's very helpful! Really appreciate it. Been installing systems for 10 years and still learn a ton from your videos.
i appreciate your honestly and humble nature not afraid to say you arent the best. i try to always do the same. theres always something new to learn! never cut your brain short! 👍
Wow ... I just started watching your videos and I LITERALLY had no idea before but now I am just blown away ... love watching , thanks for your channel !!
I have a Audio Control LC 4.800 amp with a pair of Audison 6/9 APX on the rear channels & 4 Audison AP1 tweeters . two connected in parallel for each front channels 150 RMS on the tweeters with the AMP giving 200 RMS Would you add the crossovers that are included with the tweets? Your input will be appreciated. Thanks
@@boondoggesp7836 active crossover is better than inactive. Protection is necessary. Give audio control a call to find out which model would be best for your setup and experience their great customer service for yourself
Thanks for making all these very informative videos. You have saved me so much time and resources by explaining it so very well. Keep up the great work.
Awsome video! I love when people fully explain the math of what their doing, it will deffinitly be going in my notebook of formula's so i can use it in the future!
Make sure it says "NP" on the label for non-polarized, meaning it has no polarity. Those capacitors are specifically designed to work with the variable AC signal that is speaker audio. If you see ( + ) or ( -- ), the capacitor will eventually fail as it's a polarized capacitor made for DC only.
I really could’ve used this a month ago before I blew one of these same tweeters. I’ll add these caps so it doesn’t happen again. Thank you for posting this.
I’m putting this in my saved so I can refer back 👍 I used to just pop some out of old circuit boards! But now I can actually use better specific ones 👍 thanks 🙏 I’m learning a lot during covid break out! 👍👍👍
I love that you did this video based off the very tweeters i have. Theres 4 of them going in, ran via dsp, but focals not cheap ill add the capacitor thanks!
Also a side note, while this is a great practice for customer systems -- A capacitor needs to be a decade lower then its crossover point to offer zero phase shift. this is only applicable with competition grade SQ cars but it is very important for perfect acoustic phase coherency. When using a 4000hz crossover slope with a 24db LR, 4000hz will be 6db down from 8000, and 2000 will be 18db down from 4000- If you used this capacitor then you would be causing a phase shift from 3000 down and on to the critical range where the tweeter hands off to the mid range. In a competition grade car it is important to make sure there are no turn on pops to begin with and one would only have a inline cap in the event of a DSP failure. But this could be likened to having a reliable daily driving car that may not have peak performance but lasts forever and having a race car that is less reliable daily but has much more impressive output in exchange.
Q.: 1. why 3.5 Ohm? Impedans is 4 Ohm in manual... 2. why 15mF ? Inside crossovers build in capacitors 2500-3500... Thanks) P.S.: Good job! 15 years working as installer but You projects is perfect. Deuch quality in The USA)
For a more exact value, in the grand scheme of things 3.5 vs 4 doesn't really matter as this cap IS NOT the crossover, but just to protect if something goes wrong. The caps in the ACTUAL crossovers are combined with several other electrical components and much more complex. Again the cap on the tweeter IS NOT ACTUALLY BEING USED, until things go wrong.
Another old tweeter protector trick is to put a 12v lamp, such as the dome lamp for your car, in series with the tweeter. I use this on addition to the capacitor on tweeters for stage sound. Lots of watts. Hooked up source, eq, electronic crossover, separate amps for each set of speakers. Just sayin. Get an old tweeter, hook it up like this, run lower freqs to it, see what happens. I blew two tweeters at a summer festival gig one summer. Fortunately I had replacement diaphragm on hand. Easy to change for the next day of the festival. With the lamps, never happened again. Try it. Quick and cheap!
My head get heating when i look at the formula.. may be I need A20 Bionic Chip to understand it... 😂 Btw, which is the best way to install component speakers? Is it install crossover after head unit or at speaker connectors at the door.pls help me...
Glad going old school and using capsitors on positive wires is still a thing. Heck before built in cross overs on tweeters it was the only way to not blow them
2009 Chevy Avalanche. Just installed Pioneer amp and 4 Pioneer 6 1/2" door speaks. Adjusted amp gain within specs and sounds AMAZING! But.....after cranking for 2 days during my 1 hour commute the factory tweets became raspy. I now have Pioneer TS-A300 tweets ready to install. They will fit stock location but I'll have to hot glue them in the A pillar factory speak cover. They came with HPFs filters. Comparing the stock ones to the Pioneers, the magnet on the stock is much larger. I figure it's a cheap material compared to the Ps. Gonna hook up the Ps tomorrow & see if they sound better. Wish me luck.
So I used jumper wires to attach the Pioneer tweeter in place of the left tweet and it initially sounded better then the factory tweet at 90% volume. I then played a high pass frequency tone on youtube from my phone. About 45 seconds into the tone the tweet started smoking then it stopped all output. I removed it & put the factory tweet back in. The Pioneers are rated 100 watts continuous. My amp puts out 60 watts max per channel. I used my Fluke meter to compare the now bad tweet with the one I had not used yet. The tweets and the high pass filter they came with both tested the same, 6.6 ohms for each tweet & 6.9 micro farad for each HPF. I put the bad tweet back in and it played the test tone for about 20 seconds till it started smoking. I am going to return the Pioneer tweets. Anybody got a recommendation for a great tweet?
(5:08) I think "AccuBASS" harkens back to AudioControl's Phase Coupled Activator, from back in the late 80s to mid90s(?). I have two of their old PCAs for home use and I will always have a soft spot for them. I prefer dbx's 120x-ds for bass restoration, though. It's more granular as for as the range of frequencies it uses for the restoration circuit. But we're talking 6 knobs on a dbx compared to just 1 or 2 for an AC unit, so it's a no brainer as far as which is more simple to operate. Anyway, I've rambled enough. Nice video! :)
Do you need to run a crossover if you don’t have an amp installed, what if you are just replacing the OEM tweeters and speakers because they are 20 years old
I’ve just spent the afternoon getting rid of this. The issue is the larger speakers are working in full range, added a crossover board and now audio is crisp.
REF 6530cx Description: 6-1/2" (160mm) component speaker system Power Handling: 90W RMS, 270W peak Sensitivity (@ 2.83V): 93dB Frequency Response: 53Hz - 21kHz Impedance: 3.0 ohms - this speaker 3 ohm, can you suggest matched car stereo for this speaker.
In my case, I have some old Japanese SONOCO loudspeakers, they sound wonderful, but the previous owner had no better idea than to replace the NEC dome Tweeters with 75W piezoelectric ones, I don't have technical information on these Tweeters and the factory doesn't even exist anymore. They are from 1975/79, my question is if I put in that place of the piezoelectric some of Domo that Wattage must have? What capacitor to put to make sure they don't burn or even my fear is that the amplifier will be damaged. 🙄
I got a dsp in my car and it got professional tunes I want to add tweeters in sail panel if I do would I have to get it retuned wanted to know cause tuning is expensive?
The principle of using a capacitor as a high pass filter to protect the tweeter against damage due to low frequencies is a good thing. But using a non-polair electrolitic capacitor degrades the sound quality a lot. Use at least a MKP type capacitor. Yes, it will be bulky and cost some bucks, but it wont affect the sound compared to the type used in the video.
I'm also concerned about the phase issue. That cap adds -6dB/oct slope there. 3000hz is pretty close to 4500hz and if using -6dB or -12dB slopes it might be too close and affect on the sound. So it means the 3000hz point makes the total slope being -18dB/oct if the crossover is -12dB/oct. Also the phase turns at that point too.
Don't get caught up in the exact numbers used for this example. If you are using such a shallow slope (which will lead to other issues transitioning from the mid) then obviously you would want more seperation. For a 4th order crossover you would never in a million years hear the difference between protection cap and no protection cap.
Yep. That's what I meant just pointing out. Lower cap, no problem. Maybe one should figure out the optional crossover area to be used and pick the cap size small enough to be out of the way. Steeper slopes naturally decrease the effect.
Love the video and got me thinking I could do this. Except alpine doesn't list any info like this for their tweeters. Called alpine and was told it isn't listed because it isn't necessary. So I'm sol?
Got some Hertz C26 tweeters to replace some Alpine ones that were fried in an active setup. I too calculated 15μF resistors for the new tweeters. The new speakers had 3.3μF on them, same as the old Alpines that were fried. I calculated using the formula that the cutoff for 3.3μF comes to 13,000Hz. What gives??? Decided to leave the factory ones in place partly because its quite difficult to source said capacitors where I live....
I would put the helping hand for soldering on the other side of the solder. Between the joint and Capacitor to act as a heat sink. Extra protection for the component.
@@hausboxaudio didn't help. Haha, I just had to swap wiring around to the fronts only and fade it to the rear. Unfortunate but it just had to happen that way.
I have questions for you... I love your info and your channel and all the videos you post. I am considering installing an audio control epicenter plus on my 2012 Escalade ESV LUXURY and want to do it with a wiring harness instead of finding, cutting and soldering wires into the harness. Is there a harness that has this interface? I just want the plug and play ability to allow my BOSE system to work with an easy plug and go. I am adding 3-15" Eclipse subs, a Goliath 4k amp with a yellow top, second battery. Please help. And keep up the awesome work.
I have new tweeters for my truck. They came with Bass Blockers and Small black capacitors. Do I need both on the speakers? Or do I just need one or the other. I’m confused. Are capacitors and bass blockers the same thing? Really appreciate the help brother.
2 questions: 1- Infinity Ref 3032cfx come with capacitors, I assume they would be the correct ones to use, correct? 2- Is soldering necessary, or can it be twisted and wrapped?
What about the phase delay introduced? For example if we have at 4500 Hz a 2nd order low-pass and a 2nd order high-pass filters, the former for the Woofer and the latter for the tweeter we obtain a flat freq response, but with this capacitor we add a new pole in the transfer function of the overall tweeter High pass filter. And what do you think about having that kit Focal KX2 120W 2 Ohm in each door powered by audiocontrol d-61200 which has 200W per 2 Ohm Channel? Thank you Mark I love your Channel. P.S. I have used MATLAB to tune the band pass filters of the dsp and crossover together with and without capacitor and in the second case It Is a bit difficult ti obtain an Ideal flat freq response. With your experience What do you think?
nice video. got a question. i calculated my new tweeter. i got 11,14 uF. How do we calculate the voltage. the original tweeter in the car has a 63 volts capacitor. or can we use just 100 volts. the new tweeter has 30watts rms and 60 watts normal How does this work. is there difference between polar and non polar capacitors
Amazing video. One question, Since I have an empty slot for tweeter at my car pillar, I want to add a tweeter and I already bought one. I saw that my tweeter already has a polarized capacitor attached to its terminal. So, do I still need to use a crossover for my tweeter? For additional info, my car speaker system is 2pcs "2 way coaxial speaker" and 2pcs "mid base speaker". Appreciate if you could help.
Do capacitors for tweeter control power output? I mean if the amp is 300 rms x 4, does the amp send the same amount of power to tweeter and component sub on that channel?
I have mid tweets FS value of 111 hz so a 390 microfarad cap. I notice the ones I’m looking at are 400v does the volts matter? Ones in the video are 100. Just checking I know you only say the microfarads matter but I want to make sure.
So do I run this directly to the front component? Do I just set the crossover for the component at the dsp and let it ride? Does the high frequency roll off of the mid bass?
Awesome, thanks for the info! I ordered some Kicker speakers and I noticed they came with two sets of harnesses. One with capacitors and one without, I was curious as to why
Okay stupid question here, 1. If im running active cani jist use the crossover that came with the focals for the tweeter only and then just run another wore for the midbass that came with the component set? Thank guys just new to this whole "active" thing trying to figure it out.
I have a hissing problem when nothing is playing and engine off. 09 altima. I believe they put a capacitor on the dash speakers. Could adding a correct capacitor possibly fix my problem. Also ive read its common in cheap android head units. Going crazy trying to trace down the problem. Sloght hiss as soon as volume goes to 1. Unnoticeable with music on.
Thank you very much for this video. Do you know from where I can order bennic bipolar 50wv 270uf capacitor for my JBL CLUB3020 3.5" 120W Club Series 2-Way Coaxial Car Speakers. Please let me know. Thanks

15uf capacitor will allow more low frequency which is harmful to tweeter. Lets watch the impending smoke.😢
One case where "putting a cap in it" is actually a good thing! -Gangsta D
True, don't be a big dummy.
He forgot to say that the cap must absolutely be a bipolar one, and that the voltage of 100V is recommended.

Do you need to run a crossover if you don’t have an amp installed, what if you are just replacing the OEM tweeters and speakers because they are 20 years old
In my old speakers capasitor is connected to negative is it ok or should I change to positive?

What if the tweeters I’m getting already come with it already and they just give me the other side could I use a crimp/solder fitting?
The principle of using a capacitor as a high pass filter to protect the tweeter against damage due to low frequencies is a good thing. But using a non-polair electrolitic capacitor degrades the sound quality a lot. Use at least a MKP type capacitor. Yes, it will be bulky and cost some bucks, but it wont affect the sound compared to the type used in the video.
I'm also concerned about the phase issue. That cap adds -6dB/oct slope there. 3000hz is pretty close to 4500hz and if using -6dB or -12dB slopes it might be too close and affect on the sound. So it means the 3000hz point makes the total slope being -18dB/oct if the crossover is -12dB/oct. Also the phase turns at that point too.
Don't get caught up in the exact numbers used for this example. If you are using such a shallow slope (which will lead to other issues transitioning from the mid) then obviously you would want more seperation. For a 4th order crossover you would never in a million years hear the difference between protection cap and no protection cap.
Yep. That's what I meant just pointing out. Lower cap, no problem. Maybe one should figure out the optional crossover area to be used and pick the cap size small enough to be out of the way. Steeper slopes naturally decrease the effect.

1- Infinity Ref 3032cfx come with capacitors, I assume they would be the correct ones to use, correct?
2- Is soldering necessary, or can it be twisted and wrapped?
Can i use factory capacitor but it was attached to black wire ?
0,159/3000x3,5=0,0001855. Where do you get 0,0001514 from? Maybe I am counting wrong?
You are doing the calculation in the wrong order. Look at the parentheses: You are doing (0.159/3000)x3.5 while the correct one is 0.159/(3000x3.5).
Love the tip to leave a tab in case you need to remove, the tesa tape equivalent I use is very hard to find the seam.
What about the phase delay introduced?
For example if we have at 4500 Hz a 2nd order low-pass and a 2nd order high-pass filters, the former for the Woofer and the latter for the tweeter we obtain a flat freq response, but with this capacitor we add a new pole in the transfer function of the overall tweeter High pass filter.
And what do you think about having that kit Focal KX2 120W 2 Ohm in each door powered by audiocontrol d-61200 which has 200W per 2 Ohm Channel?
Thank you Mark
I love your Channel.
P.S. I have used MATLAB to tune the band pass filters of the dsp and crossover together with and without capacitor and in the second case It Is a bit difficult ti obtain an Ideal flat freq response.
With your experience What do you think?
What is the name of the constant and the formular you use, cannot find it on the web?
nice video. got a question. i calculated my new tweeter. i got 11,14 uF. How do we calculate the voltage. the original tweeter in the car has a 63 volts capacitor. or can we use just 100 volts. the new tweeter has 30watts rms and 60 watts normal How does this work. is there difference between polar and non polar capacitors
Amazing video. One question, Since I have an empty slot for tweeter at my car pillar, I want to add a tweeter and I already bought one. I saw that my tweeter already has a polarized capacitor attached to its terminal. So, do I still need to use a crossover for my tweeter? For additional info, my car speaker system is 2pcs "2 way coaxial speaker" and 2pcs "mid base speaker". Appreciate if you could help.
Very cool and easy to understand!
Thanks and cheers.
hi 👋 quick question if I'm using 6k capacitor on tweeters then amplifier frequency is 3k total hz is playing tweeters at 18k hz.
Do capacitors for tweeter control power output? I mean if the amp is 300 rms x 4, does the amp send the same amount of power to tweeter and component sub on that channel?
I just did this on my tweeters, very helpful!
I have mid tweets FS value of 111 hz so a 390 microfarad cap. I notice the ones I’m looking at are 400v does the volts matter? Ones in the video are 100. Just checking I know you only say the microfarads matter but I want to make sure.
So do I run this directly to the front component? Do I just set the crossover for the component at the dsp and let it ride? Does the high frequency roll off of the mid bass?
Very good tutorial.. Thank you Mark
Awesome, thanks for the info! I ordered some Kicker speakers and I noticed they came with two sets of harnesses. One with capacitors and one without, I was curious as to why
Crutchfeild has some nice ones.
Nice Video.Thank you
Okay stupid question here,
1. If im running active cani jist use the crossover that came with the focals for the tweeter only and then just run another wore for the midbass that came with the component set?
Thank guys just new to this whole "active" thing trying to figure it out.
Nice video, very useful.
One little question:
From where comes the 0.159 in the counter?
Many thanks for the help.
its 1/(2*pi)=0.159
I want filter car audio tweeter so let me know about the value need to use?
I have a hissing problem when nothing is playing and engine off. 09 altima. I believe they put a capacitor on the dash speakers. Could adding a correct capacitor possibly fix my problem. Also ive read its common in cheap android head units. Going crazy trying to trace down the problem. Sloght hiss as soon as volume goes to 1. Unnoticeable with music on.
Somebody needs to make an App for this and a lot of other related car audio problems
Thank you very much for this video.
Do you know from where I can order bennic bipolar 50wv 270uf capacitor for my JBL CLUB3020 3.5" 120W Club Series 2-Way Coaxial Car Speakers.
Please let me know.
Thanks
