How do i upgrade the audio - 2019 CX3

Hi, I've just bought a new CX3 (Touring), and I'm surprised how bad the audio is.

I want to improve it.... can I just simply get better speakers installed? Or will I need to replace the head unit to get a noticeable improvement?

I imagine changing the head unit is a big job, and will have warranty implications.

Thanks, I don't know much about cars but love my music!

Cheapest way would probably get a shop to install a simple aftermarket amp and maybe new speakers if you want to go for the full set.

Changing the headunit is where the fun gets absolutely chaotic. There are random chinese sellers which make full android os headunits with built in amplifiers (similar to any aftermarket headunit) but cross wiring that and replacing the touchscreen infotainment system with those parts have been uncharted territory. Some older cx-3s in specific regions have just a radio with a volume knob where the touchscreen would normally be and that is what the android headunits are meant to be a replacement for. Unfortunatly the full touchscreen oem models have system settings on it which can change the hud, light, alarm beeps etc of the car so I am not sure what would happen if you disconnect the oem unit there. I feel like one day I might personally go down this route but there is too much risk involved since I dont know if taking out the oem unit is going to cause any issues with the car/codes/lighting etc

Here in Europe Mazda is selling an audio upgrade Kit from Alpine.
You get a subwoofer, an amplifier and two tweeters.
This is the product number: DC3L-V6-800A.
I don't know if it's available in Australia but you can always ask you dealer.

Thanks... Doesn't look like the audio upgrade is available here.
And agree the OEM meddling looks risky.
I contacted a few car audio places.... I've had two responses. One suggested just replacing speakers with Coaxial ones, $180 each.
The other proposed a full kit out, for between $3k-$10k!
Replacing the speakers is more in my budget, but not sure how big a difference that will make...?

You would most likely notice a difference even if you only replace the speakers.
An amplifier and subwoofer would add even more and you should be able to add those to the original headunit, though I'm not 100% sure.

I have the Bose system in my 2016 touring and IMO it’s not that bad and I thought the Bose was standard in the touring.

where the whole problem lies here with Mazda Australia, even our top line model does not come equipped with a Sub, or Bose system, looks like that is only in o/seas versions of the car, what a shame.

I have put in a Connector between the factory TAU wiring, this is what I have used.

MY CAR IS A 2016, please check as the connections may be different in the latest 2019 version.

Maybe this will be helpfull for future install issues.

My huge gripe also with the Factory System is that is has Bass Roll Off, so we don't damage speakers at high volume, that plays a part also with hooking aftermarket stuff up.

There is some good helfull advise on this Forum Link, as others have done Stereo upgrades.

I am extremely happy with the basic speaker upgrade we did. No amp was needed in the end. We went with entry level Hertz speakers, the four 6 1/2" swapped out.
Sounds significantly better then stock..
