How to: Citroen C4 speakers replacement

[@4krist]

I buy Hertz K165 and fit perfectly and work with factory tweeters.

[@rosenvalchinov116]

Hello, 2 years later 😅 I’ll be thankful if you answer my question and help me! The car has 4 speakers (2 front and 2 rear) 16.5 as you already said. But there are 2 more smaller ones on the dashboard right under the windshield, which are tweeters. What about them? What’s their size and how to replace them?

[@radxtech6069]

Hi, The tweeters are held into position through a twisting motion, a proprietary method. If you search images of the factory tweeters you will see some "wings" built into them, which grab and hold onto slots dedicated for them. Replacing them would require some tinkering for this car model because of their location. A creative idea would be to use a spare set to chop off the existing tweeter and "glue in" an upgraded unit. As for size, it shouldn't be a problem. For example the Hertz Dieci DSK 165.3 kit has tweeters that will fit (i'm using this brand name as an example, not promoting or anything else) as sold by some vendors as dedicated replacement for C4 2004-2010

@@radxtech6069 thank you for the answer! For now I’ll try with the 2 rear and 2 front speakers. I am still looking for the best as price/performance. Maybe I’ll update you when I am done.

Thanks you

Thankyou for posting this video, I will be doing the same car this week.

[@MrBrandonLau]

Did you use 2 ways or components?

[@radxtech6069]

Hi, Just a 2 way. Quick and easy swap for everyone with some basic skill of wiring. Sound is a lot better than stock for the regular person. Has good bass, no distorsions. Don't use added bass or enhancement in the menu option for the factory headunit.

[@radxtech6069]

Will post some other mods and maintenance for this car, that owners can do with basic knowhow and tools.

[@fugdefano]

are the rear speakers the same size. due to water damage both my left speakers have perished and i would swap my rear right for the front left. im from Yorkshire so thats the cheap option

[@radxtech6069]

Hello, After you remove the good unit from the rear just see if it's 6'5" and you will know it should fit.

[@nikospapageorgiou57]

First of all thank you for showing how to do it. Second this is ridiculous I am surprised you don't have to disassemble the entire engine just to unscrew a simple speaker out. How difficult would it be for the speakers to simply have a plastic cover that you can remove to gain access to them???

[@Slim31-e3m]

Merci beaucoup. Auriez vous fait la même chose pour l'arrière ?. Cordialement merci

[@radxtech6069]

Not for the rear now. When have the chance to make for rear, will share instructional video

[@Adameeriu]

So, you can simply attach it to the factory radio right? You dont need an amplifier, due to the higher performance of the new speaker?

[@radxtech6069]

There is no problem. An amp will always be a good thing even on stock speakers the same as better speakers will be performing better than stock ones. Amp + upgraded speakers is even better.

[@Adameeriu]

@@radxtech6069 thanks for the info :)

[@Adameeriu]

@@radxtech6069 i just finished with the same speakers you used. Sounds much much better even without an exta amp. Thanks again. But even if I change the rear ones with the same type of spekers is ok? Can the stock amp handle it?

[@vadrouille4-975]

Hello, does 17cm diameter speakers can go in it ???? and also what is the size of the speaker in the trunk please? Thanks for the video really useful

[@radxtech6069]

16.5cm (or 6.5) inch is the size for the front and for the rear. If you wish to try different size best to open the door and use a cutout shape of the 17cm size to see if it works

[@vadrouille4-975]

@@radxtech6069 thanks my 17cm Pioneer fits perfectly

[@radxtech6069]

@@vadrouille4-975 That is good to hear my friend. So small difference is still capable to fit.

[@HarpreetSingh-yp3je]

Hay, what is the Speaker mount depth?

[@radxtech6069]

Hello, Here are specs for the installed speakers in this video and they fit inside, so you can use as guide if you want to install others. hertz-audio.com/product/car-audio-coaxials-uno-x165/

[@TechitMusic]

I am looking for all speakers' dimensions for my citroen c4 hatchback 2006 and i can't find them anywhere. Can you help me ?

[@radxtech6069]

Hello, They are 165mm / 6.5 in

[@vincentnevanpera6273]

Hi , do you think Sony speakers 16x24cm 6”x9” 2way can fit? :)

[@radxtech6069]

Hi, I don't think it will work because is an oval. or maybe with some modifications!? Use round speakers 165mm/6.5 inch And for cable connectors, I found on aliexpress connector adapters from citroen/peugeot speakers to the universal blade type.

[@paulturner4161]

if your replacing the old speakers in any car, then your probably throwing them away so just cut off the old connector wires as close to the speaker cone as possible and crimp blades connectors onto them wires and plug onto the new speaker, thus creating an adapter, and giving you more space to work with.

[@radxtech6069]

After the video i have found connector adapters for the oem plug, thus avoiding cutting wires and keeping clean install. Ebay, aliexpress, amazon and such...

[@MrBrandonLau]

Did you use component or just 2 way?

[@AnmolMishra-rz5jj]

Can you use 3-way speakers ?

[@radxtech6069]

Not needed. There isn't any justified reason to have them struggling inside the door. Upgrade the tweeters in the dash near the windscreen area if you want. And add a subwoofer in the trunk on the side gaps where the factory woofer unit is located (on select trims) example in link below c4owners.org/plugins/forum/attachment/24127/1353856605_24127_FT175568_jblboot_.jpg

[@MrTherandomvideo]

Hey RadXTech, I have just started to upgrade the quality of sound for my Citroen ( In Latvia we call it a Lemon because lemon is Citrons ) however I just put in an active subwoofer and not sure where to add that blue cable the one gives impulse to the subwoofer.... i tested it with puting to the baterry but well thats not right... anyway the main question is - whats the W of original speakers and why did you replaced it ? and how about the other speakers ? Thanks in advance , peace and love !

[@radxtech6069]

Hey Thanks for your interests. The rear speakers on the Citroen C4 mk1 coupe (3 door hatch) and berline (5 door hatch) are 165mm in diameter For the rest of the components will share the replacement of factory head unit with a new touchscreen LCD display (android 10) As they are different from stock, could not help you with subwoofer specs on the factory unit.

[@antonistsimpouxis9172]

Hello,can you please tell me the size of the front speakers?

[@radxtech6069]

Hello Yes is 165mm (6.5 inch), i think i said in the video when installing and presenting the process

[@antonistsimpouxis9172]

@@radxtech6069 i am sorry, i watched fast forward without sound. Just to get am idea at the moment. Thank you for the info.

[@radxtech6069]

@@antonistsimpouxis9172 No worries, i wasn't sure if I had mentioned in the video. If i didn't at least i offered the info now. Cheers. Also, I think you can buy adapters for the citroen speaker plug, i saw on aliexpress recently. When i changed these speakers i just cut the citroen wires and soldered directly. With the adapters i think you'll keep the factory plug and just solder on the adapter wires the connectors.

[@jamesjessop7065]

And to think I was going to check if they would do it at Halfords

[@wispa1a643]

Is DS4 the same?

[@radxtech6069]

Not sure. This is for the first generation Citroen C4. The first Ds4 shared the second generation of Citroen C4, the B7 version)

[@Emi_Stoico64]

You don't need cut the wires..better to buy adapters in ebay or amazon

[@radxtech6069]

Do you know the name or model of the adapter you mention? Thank you

[@jamiestrevens854]

Where is the finished result

[@radxtech6069]

Sadly youtube blocks for copyright reasons the video with the sound comparison stock vs these speakers. I shall try to upload on a different site and see if it is allowed there. You can use any speakers you may like that fit the 165mm diameter. As shown in the video some cutting of the plastic shroud may be required for some speakers because of the connectors position.

[@radxtech6069]

Hello, Lets see if Vimeo blocks the video At start is the new speaker, mounted on the passenger side, and as i move to the left, to the stock speaker, you can hear the volume is much lower. Nothing else changed, just the right speaker and gradually balance to the left speaker But this is this speaker. Other people may want other brands/models, the uninstall and install is the same vimeo.com/559053859
