Hello everyone!! 1 week in with my new mazda6 signature, and I'm really liking the acceptable clarity of the bose system. The one thing I noticed is that it barely has any real bass, is this normal? I'm fine with a system that is crisper with less bass as I listen mostly to rock, but I'm just curious if this is normal as it is my first mazda. Thank you!!

Have you checked what the "Bass" level is in the equalizer setting?
I think mine is a few ticks higher than the default setting.
I find the system has a good enough of bass. Just depends on what you're listening to, maybe.


I've realized that the door speakers are woofers of some sort and should be providing the bass for your music. When I first start my car, there is a moment (while the amp is not powered up) that the system sounds like it's lacking and then you can hear the door speakers activate a bit after and the bass is heard then.

The car has no dedicated sub, with the large speakers in the front doors acting somewhat like a pseudo-sub. IMO the Boss system is definitely lacking in bass power and is also quite muddy from around 200Hz to 1500Hz. Otherwise its not half bad, its just unfortunate as despite my broad range of tastes my favorite genres are quite bass heavy, so it is very noticeable. Definitely need to have a proper sub installed with some of the front speakers being replaced and an aftermarket 5-channel amp install being a luxury bonus if money is no object. Its a good starting point, but certainly not a great system out of the box.

Firstly, congrats on the new car! I've had my 18' Signature for just over 6 months now and so far it's been fantastic so far!<img src="http://forum.mazda6club.com/images/Mazda6Club_2014/smilies/tango_face_smile.png" border="0" alt="" title="Smile" class="inlineimg" />

To answer your question, the low-frequency response is undoubtedly not great from this Bose system. The system as whole is really just a hair above average imo. The speakers in the front doors are in fact subwoofers. They are the only speakers in the vehicle responsible for reproducing low frequencies. There is a resonance peak where they do sound good @ ~60Hz (judging by ear), but as you go higher the sound quality just drops off and it becomes annoying vibrations instead of proper sound. The entire idea of putting subwoofers in the doors is just awful and entirely cost-related I'm sure. But, thankfully Mazda has FINALLY realized/admitted this and is going with a new design for the 2019 Mazda3. I seriously hope this carries over to the rest of the vehicle line then too.

There's a few things you can do to help with the bass and clarity though:
  • Easiest way to increase bass is to fade the audio to the back of the car a couple ticks. While this will lower the overall volume up front just a tad, the subs are seemingly unaffected and will audibly sound louder since they're up front. This will also diminish the front sound-stage effect a bit, but in return gives you a more surround effect which I personally tend to prefer.
  • Use an app with a built in EQ. Spotify for example, while not providing the best EQ, still gives something and allows you to make more precise sound adjustments before the audio gets to the head unit (+ works with CarPlay).
  • A slightly more involved measure that I've done for better mids & highs is to replace the front dash speakers. Personally I've replaced all 3x front speakers with FaitalPro 3FE22 (4 Ohm) speakers and the audio sounds much more clear and full now. Lots of threads about them over on DIYMA. Power spec wise they're drop in replacements, but you'll have to get a little creative with the wire connections and mounting method. I opted to make some custom 3D printed mounts, but you kind'a can get away without them.
  • Lastly, the most generic method is a trunk sub for added bass, but I think without upgraded mids first this isn't a good idea.
thank you so much!! And thank you for your advice, I'll try these options for sure

Wow, interesting to hear this feedback from people. I find the low frequency bass to be drastically too high in this car and keep that setting on -5 or -6 "clicks" in the infotainment settings because not only does it overpower vocals, but it shakes the doors to the point of being obnoxious while driving.

My vehicle: 2018 GT reserve

Musical preferences: Blues, various electronica and 80's new wave.

So there is plenty of bass in these genres, enough to obscure the actual music with door shaking (literally) bass in the 6.

(If you enjoy 80's new wave, here's my soundcloud playlist that we play in my bar at Burning Man. About 35 hours of material: https://soundcloud.com/user7786278/sets/new-wave)

Turn on Center Point. Now adjust the fade about halfway to the rear. Stop when you hear the rear speakers over the front. Now adjust the bass to near max. I added a little treble also. There is a lot of bass, and it is clean if you listen to piano or classical type music. The system doesn't seem to be tuned for heavy rock.

Hi!

You just got me wondering... When I got my car ('18 GTR), some high frequencies in certain songs would cause the tweeters to distort. It was sort of a crackling sound, very noticeable for me. At first I thought that the speakers just needed to break in, but then remembered that this kind of distortion can be introduced by clipping from a DSP or something such. I deactivated Centerpoint and the distortion is completely gone, in all tracks and at all volume levels. So, it would seem mine was a case of simple bad luck. Do you think I should have it checked at the dealer?

Though as you know I'm pretty much ditching the Bose system entirely, your first suggestion is the first thing I did on the way home from the dealer. Made the system sound average at last. :grin2:
