In saying that you do no want speaker with a high power handling but too low a sensitivity, as they can handle the power but don't necessarily respond efficiently to the signal.
Okay thankx Craka i'm not an audio specialist , a bit chinese to understand sometimes
I prefer to ask even if it can be a bit annoying....... therefore if i take speaker of 90w rms for front and rear , the H/U will be able to handle without problem ?

As Craka mentioned, stick with a speaker with a high sensitivity, anywhere from 90 db upwards. I have a MY16 NX with the newer style Apply Carplay unit, have gone with 50w rms 91db to match the stock h/u. No point going with a set which higher power handling as output will be less efficient.

Hi there , after searching again and again since this morning , i found a pair for the front doors .

The specs is :

-70w rms
-impedance 3 Ohms
-Sensivity 94db
-crossover freq. 3500hz
-Freq.range 49-22000hz

What do you think about the impedance ? Sensivity is okay , up to 91 (thanks Craka & DC80)

the two other specs in hz , i don't understand what they mean

Impedance of speaker should match impedance of head unit for maximum efficiency and also not overload headunit internal amplifier by using too low of impedance speaker . Default for most car audio head units are 4 ohms. IMO I don't think 3ohm speaker will be too trouble some on a 4 ohm head unit.

The cross over frequency is the frequency at which the cross over filter passes higher frequencies than 3500Hz to the tweeter and and lower frequency of 3500Hz to the woofer, that is only a basic description but that kind of is the concept of what the cross over does.

The Frequency response is the range of audio frequencies that the speaker set is able to generate a quality audio output. Frequencies outside this range the speaker is not able to produce effectively. (In addition bugger all people would here 22kHz or higher)

Thank you for all this information
Do you think I should try to find some with 22K ++ hz? Or will these do the job properly ?

Almost nobody hears over 20 khz at their best time (15 yr old?) and it goes down with age, i you are over 40 years old you probably dont hear over 15 or 17 khz, and if you were a fan of loud headphones when teenager even less. And then, in reality high frecuencies need a direct path from speaker to ears so tweeter positioning is even more important... just dont worry about frecuency response, all will do fine to go high enough, differences within the frecuency response that affect sound quality cannot be spotted from reading specs.

Just go to high efficiency (94db or more, easy to find) speakers that will need less power for any given volume you need, specially if they are 2 or 3 ohm that suck more power from the amp.

what's up guyz ?

So the pandemic is not helping with international delivery . The speakers i wanted is not available in my little island .

I found a pair of pioneer locally at a correct price (TS-A1600C) , the only downside is that they make 85db

There is an adapter provided in the kit, this is also why I took it , basically, I wanted to change the backs, but my seats are in the living room for a while, and my partner is starting to get tired of having them there So Iíll do the rear later .

Here some pics
To limit vibrations, I use self-adhesive foam between the door and the adapter


I also put some between the speaker and the adapter


If ever, this assembly is not correct , just tell me

I had to modify the support a little, enlarge some holes , this is what it gives with the woofer in place


I also made another small modification to pass the electrical harness


I kept the connection of the original speaker to connect the woofer

Hey, not wrong about international delivery very few flights are going anywhere in the world at the moment I believe. Call me ignorant but I had to look up where Reunion Island is, it appears to be quite a isolated location, I'd imagine getting getting freight at any time is costly.

I'm not sure on you model pajero but did it already have split front speakers. ie Woofer in lower door and tweeter up high inside of door near where mirror connects?

I have no doubt the pioneers coaxial speakers you have will improve the mid and lower range frequencies over the factory speakers but having the tweeter down in the lower door won't product as good a sound stage of having a separate tweeter up higher in the door. Tweeters produce higher audible frequencies which are more direct than lower frequencies and a best nearest to head height as possible.
