Infiniti M35/M45 Audio System

Hi all - I'm interested in getting input from owners of the M35 of their impressions of the audio systems available for this car. The base system is a 6-speaker configuration, and there's at least 2 optional systems - one is a 8 speaker system made by Bose and a second is the 14 speaker surround system also made by Bose.

I was pretty impressed by the sound system in the G35- but that's apparently not the same as what's available for the M35. The M base system seemed to be unimpressive in my test drive, but I haven't heard the two Bose systems. I do know that just because it's a Bose system doesn't make it great---I have one Bose premium system now in my Audi A4 - and it isn't in the same league as the BMW upgraded sound.

    My last car was an Audi A6 with the Bose system. Two things: the Audi is quieter so you could hear what it did output easier; the Infiniti version is similar, but not identical; the 5.1 channel system of their best system is nice - you have a stereo pair of speakers on each of the front seats. If you have access to music that makes use of the 5.1 sound, then it is really nice. I didn't want to spend that much, and ended up with the 2-channel Bose system. I also spent nearly $1k to add some Dynamat, which made the car significantly quieter.

    Just keep in mind that the Bose 5.1 surround sound audio (and its specific speakers in the seats etc) is only used by discs played in the DVD player in the center console, not the 6-disc changer in the dash. However, it does sound great and I enjoy playing (listening not watching) concert DVDs etc on the system.

    I have the 8 speaker system and I think it is very good. I guess the 14 speaker system is probably better but I like to crank it up and the 8 speaker system more than meets my needs. I've also had clients in the car who are in the car stereo business and thought the system was excellent. If you're not an audiophile, I'm sure the 8 speaker system will more than get the job done.
  • Hi,
    I own a 45 sport with the 8 speaker bose. In my opinion it is subpar. How can a 55 k plus car not have a subwoofer?
    I am not happy at all as my former Bose system in a 2004 A6 was much better all around.
    I was not able to get the 14 speaker system in my car at the time I needed vehicle delivery. I don't think it has a sub either?
    Good Luck
  • I have the 5.1 surround on my M35 (14 speaker system). with this system at least, you dont need a subwoofer. The bass is deep and rich without it. I came out of a car with a dedicated subwoofer, and this system is much better. The sounds all around are cleaner and more expansive. I really honestly would say that it is the best sound system of any car I have had, including acura's dvd-audio and mercedes.

    I just got my 2007 M35 a few weeks ago with all the goodies, including the 14 speaker system. I have to say that the Bose system continues to disappoint me in nearly all regards. A car of this caliber (and cost for the premium sound) sure leaves a lot to be desired, particularly if it is not in the 5.1 mode (which, in and of itself, lacks timbre and tonal qualities of such an expensive system). Frankly, my Polk speakers with OEM head unit in a 2005 Chevy Silverado sounds much better on non 5.1 audio. If there is anything that Infiniti can do to upgrade the M series, it is in the audio area - it's a very disappointing aspect of an otherwise great car - IMHO.

    I would have to agree. We also have a 2007 m35x with 14 spk Bose system, and I think it is significantly inferior to the premium sound systems offered by other car makers. Wifes father has a Mercedes S class which sounds stunning by comparison, as does her mothers audio system in her Jag XJ. We have driven Bimmers in the past and always got the premium sound systems, which I have to say were also superior to the premium sound in the Infiniti. I do like our M, but I was somewhat disappointed with the pseudo premium sound of Bose.
  • james27james27 Posts: 433
    One of the prerequisites of a good sound system (IMHO) is a quiet environment so that you can hear the music without competition with engine and road noise...the M's are fairly noisey, so unless you are sitting still, you will never get the full benefit compared with cars that are actually quiet while moving. Given what it has, it's not bad.

    ". . .compared with cars that are actually quiet. . ."

    Hmmm - - good point.

    The 3.5 litre Nissan engine may be thirsty for fuel, but at least it's noisy.

    Before you draw a possibly incorrect conclusion, we have a '04 PF in our household & don't mind the noise so much, though we'd like better fuel mileage. Besides which, the only vehicle I've ever driven over 225K miles is a Nissan product.

    Crude, but effective.
  • Hi everyone, first timer. I am planning to purchase or lease a 2008 M35 next month.
    Has Infinity upgraded the stereo? I leased a 2007 on biz a few months ago. I was typical rent a car beat up a little. The throttle from a stop is a real neck jecker. Nomatter how I tried it continued, so I got used to it. I heard they fixed it with a software upgrade. Thanks for reading. I look forward to your wise advice.

    Welcome to CarSpace - glad you found us! :)

    With the M35x, you do get an option to slow the thottle response down a little if you select the snow mode. This also always starts in 4-wheel drive mode, so I'm not sure how that would affect reliability in the long term. Personally, I let the car start to roll after a stop without touching the gas, then once it's moving accellerate away. Don't know about if they've changed the programming, although it should be easy to do.
  • I've had my '07 for 2 months now and find the stereo one of the most disappointing aspects of the vehicle. Bose has never failed to disappoint me in tonal quality or spatial reality of the soundstage. In the M, Bose has gone to new depths of performance. Frankly, my 99 Toyota Avalon had a better system than this vehicle. Oh, and try to explain that to your service advisor to see if there is really a problem - are they all tone death?

    From what I have read, the 08 is basically the same in performance and sound realism.
  • Thanks for your input. I'll probably still buy it. Maybe I can get a better aftermarket
  • Is there an iPod/mp3 hookup in last year's model?
    If no, is there a way (some sort of aftermarket hardware?) to be able to control an iPod from the nav screen?
  • kobe5kobe5 Posts: 1
    I am also wondering if there is an iPod hookup.
  • bocatripbocatrip Posts: 194
    I've heard alot of negative criticism on the bose systems for the M. I have an 04 G35 Coupe with the optional bose system and it too had quite a bit of negative reviews. However, for my needs, I actually find it to be ok. I was wondering if anyone is familiar with this system and can compare it to the basic system that comes in the base model M. If it is close in sound quality, I would be fine as I'm planning on purchasing an 08 M35 with no options.
  • Just picked my 08 M35S, w/ tech pkg. Music is passable, but I have heard better, much better. The tech pkg is worth it alone. Buy one and spend a few bucks at the auto sound shops.
  • Well, we just bought a 2008 M35X a few days ago and are happy with the sound system. High and low notes are crisp and clear. We've had both good and not so good Bose systems in other cars we've owned, and the eight speaker system on this car is one of the better ones. Don't know if they improved since 2007, but no complaints from us. And we're pretty picky about the sound.

    On a related topic, loading music into the hard drive is a pain -- you've got to do it through CDs -- won't accept recording from a flash drive or I-Pod. This "feature" definitely needs work.
  • xargsxargs Posts: 3
    Yes, the Music Box system is a bit of a disappointment. I was expecting to be able to copy music from the Compact Flash slot (or possibly even the iPod) to the internal hard drive. No such luck. The iPod, hard drive, and CF slot are all independent inputs which are completely walled off from each other. This means you also can't do something like have a random shuffle from multiple sources.

    Another problem is the Gracenote database. Any new CDs aren't going to be in it, so you have to enter song information yourself (I just popped in the Hairspray soundtrack, and it wasn't recognized).

    So I guess I'll be sticking to the iPod interface.
  • bocatripbocatrip Posts: 194
    I just came back from test driving and listening to the base sysem of an 08 M35. I'm comparing it to the upgraded Bose System I have in my 04 G35 Coupe with premium package and I can say for myself it sounds as good as the system I presently have. I did not get a chance to listen to it at length but it was more than satisfactory for my listening habits which is primarily burned CDs. Everyone has their own tastes, but I remember after purchasing my Bose in my Coupe everyone was trashing the unit. I never understood this as I found it to be fine. I guess it's all subjective.
  • I test drove a M35x the other day. The nav screen listed the XM station but not the actual song that was salesman switched to a seperate screen where the song was listed. Is this correct?
  • xargsxargs Posts: 3
    Yes, it's correct. The XM info appears on the main status screen (press STATUS), or on the XM screen. It doesn't appear on the map screen, which is a bit odd since iPod info does appear on the map screen.
  • Hmmm...weird. :confuse:
  • dhellerdheller Posts: 28
    Interesting, I too had a 99 Avalon and traded in for a M35. Indeed, I found the Bose on the Infiniti far inferior to the Avalon. The only salvation is XM which broadcasts 5.1 on some channels (periodically). You certainly do have to fiddle with the settings a lot, I find myself jumping in and out of the Center Point settings, for talk shows vs. types of musics, etc.

    I reading many of these posts, I find people say " seems fine...", or "'s okay...", but frankly for what I spent on the M, I would agree, it is far inferior to what it should be in overall performance, particulaly with the very idiotic iPod interface on the back of the console. Whoever dreamed that up, should be escorted to the " designer's funny farm...".
  • I'm looking to lease/buy an '07 M35x. I know this question has been asked before, but is there any way to integrate an Ipod into the existing stereo controls? It seems ludicrous that NOBODY has figured out how to do it in this digital age??? :confuse:
    Is it really that unrealistic to just put the new audio/nav system featured in the '08 into the '07?
    IF that's not possible, does anyone know how cost effective it would be to replace the entire nav unit with one that does? Thanks for help & possible options!
  • My wife got her Highlander wired at Toyota where she bought it. $150.
    Changing out the whole nav pkg sounds too expensive to me. Good Luck.
  • dhellerdheller Posts: 28
    I would expect that to be very expensive (add an 08 Nav to and 07). It would probably be easier to add XM and let it suffice while in the car. Though I am annoyed about the poor iPod interface, I find I rarely take my (new) iPod in the car. There's just so many options on XM and Sirius, I'm not sure I'll ever use iPod again.
  • I'm thinking about an Infiniti, and as a music fan would like to hear about your Pros and Cons of the audio/Nav system...esp. the Ipod interface if you'd be so kind.
  • dhellerdheller Posts: 28
    I would rate the audio (Advanced, 14 speaker system) as mediocre, at best. The iPod interface on the back of the console (2007 model) is quite useless, as it doesn't charge the unit, nor provide good fidelity (you have to really crank up the volume).

    I love the M, but the audio system is the most disappointing aspect of it (in my opinion).
