Bose Sound System or not?

[bnwitt]

I just purchased my used 2017 Rogue SV with SV Premium Package and SV Sun & Sound Touring Package. The center speaker has the Bose emblem on it and the radio is the one with the XM/Sirius button. The window sticker I downloaded from Monroneylabels.com says it had a 6 speaker audio system and doesn't mention the satellite radio or Bose equipment. I have a speaker in each of the four doors, and three on the dash lid including the middle Bose speaker for a total of 7 I can see. Now the question, every thing I find online about the Bose system says it is a 9 speaker system. Have I got some oddball hybrid or are there two speakers somewhere I am not seeing? Thanks in advance.

For the 2nd gen Rogue, the standard audio comes with 6 speakers, while the premium comes with 8 speakers and a woofer in the spare wheel. Remove the cover over the spare tire and you'll find the subwoofer, as it holds the spare in place.

Rogue One thank you sir. I had no idea that sub-woofer was in the spare tire well. So obviously I have a Bose system but I really can't tell there is a sub woofer when listening. I guess I need to play with the audio settings. All I see in the menu is bass, treble, Fade, Balance. I would have thought a Bose system would have had a more controllable EQ.

Do you know if your car is an SV with Premium Package? If you have the Around View Monitor, then you have the SV Premium upgrade.

BOSE blows. I won't bore you with all the details, but here's the cliff notes.

The sound system was designed by BOSE to stay within Nissan's budget. Most of the components are NOT made by BOSE, but selected to give the best sound at Nissan's price point.

As most audiophiles will say "all high, no lows, must be a BOSE".

Rogue One,
Yes I have the SV with premium and sun and sound touring packages as I mentioned in the first post. So what are the suggested upgrades? It doesn't look like an aftermarket head unit is practical as there are so many buttons in the factory head assembly like SXM, camera, and integral functions in the existing head unit touchscreen. Is that right or wrong? I assume I could upgrade all of the individual speakers. Any suggestions? I'm used to having some EQ bands to adjust and crossover control of the sub-woofer input frequency.

Re: Bose sub woofer in spare tire kindo weak?

You don't know the old saying? No highs, no lows it must be Bose. That said the Bose system in my 2018 SL thumps pretty good for what it is. I assume you have adjusted the bass, treble, balance, etc. already. You need the right content and a good quality recording for it to sound good. Don't expect that from the FM Radio. I thought there were two subwoofers in the premium Bose system, one in the front and one rear. The port for the front one is in the center of the dash as I certainly don't believe that is a center channel speaker in there.

Bass should not sound like 10 men beating on the side of a rubber raft, kids that think that is bass have no clue. I used to compete in sound quality 1-150 Watt class using high-current amplifiers on the IASCA circuit in the 90's and know what proper sub-bass should sound like. The bass should blend with the rest of the system and not be overwhelming otherwise you get the thunder and lightning affect. You can source low impedence mid-bass drivers you just need to see if they are 2 or 1 ohm. The folks at Crutchfield might be able to tell you that then you can source alternate midbass drivers.

Please read this thread: Retain around view cameras when replacing stereo

You can improve the overall sound by simply replacing the speakers. This will cost much less than replacing the HU and will improve the sound output from the HU. You'll find that most everyone recommends that if you're on a budget you replace the speakers first (not to mention it's an easier DIY than replacing the HU).

NOTE: Most BOSE speakers are one or two ohm. Aftermarket speakers are generally four ohm.

Thanks again Rogue One. I'll start looking at speakers.

[bnwitt]

So rather than take door and dash speaker panels off to measure ohms of each speaker in my 2017 Rogue Bose 8 speaker system prior to shopping for new higher efficiency speakers, can anyone tell me for sure what the ohms of these speakers is for sure?

[Rogue One]

The BOSE speakers are 2ohm. This has been established here in the Rogue forum, as well as other forums in NICO. Plus if you do an online search you'll find it confirmed in other car and audio forums. Oh, and in case you missed it, the BOSE system utilizes a much thinner wire as well.

Mazda RX-8 forum:

Some of the Bose speakers are 2 ohm but the main 9 inch woofer is 0.5 ohm. Yes, half an ohm.

Replacing that speaker with a 4 ohm version will be about 12 dB less sensitive - i.e. completely wrong.

If you want to replace the speakers in the Bose, be prepared to have new amps as well.

BTW, the rear deck speakers are 2 ohms. You are correct that a 4 ohm speaker with a 4 ohm resistor in parallel will lower the load to 2 ohms so the amp will be doing about twice the power. However, all of the additional power will be simply dumped into the resistor - the four ohm speaker won't be any louder.

Now there are 2 ohm speakers you could use for the rear deck. Image Dynamics make some.

Cadillac Forum:

If the car has the Bose sound system then the amps, preamp, and speakers are designed as one system - it all works one way: as designed.

You might get a 4 Ohm speaker to work if you jumped the terminals with a 10 watt wirewound 4 Ohm power resistor, effectively lowering the speaker resistance (not the impedance) to 2 Ohms. No sound quality guarantees, though - functioning impedance is a big factor in driver performance, not just simple resistance....... so now you're into passive crossover design....

Thanks Rogue One. 2 ohm car speakers are available so no need to use 4 ohm models. As I understand it, Bose did the design but the components are not manufactured by them so they are not Bose quality speakers. I installed all new pioneer speakers and a new HU in my 08 Frontier years ago and the the sound improvement was phenomenal. I replaced the speakers first and there was a pretty good improvement prior to putting in the HU. I would have stopped there, but the 2008 Nissan HU had no technology capabilities and I really needed hands free calling in that truck. I figure some high quality two ways and quality tweeters should be enough for this system. I will admit it sounds pretty good now but with my high frequency hearing loss I need a 7 or 11 band EQ or at least better speakers and tweeters to hear everything in the music I listen two. I did notice that the previous owner had the Treble almost maxed out and I couldn't really hear that much treble from the system. I'd really like to hear from anyone who has done a speaker upgrade on this 8 speaker Bose system just to get some before and after feedback. Thanks again for your detailed replies. Very helpbul.

Ok so based on the 2016 FSM which is all I have to work with at the moment The Bose system describes the front door speakers as 6.5" speakers that are designed to receive signals from the Bose speaker amp and output low range sounds, the passenger door speakers are 5" speakers designed to receive signals from the Bose speaker amp and output high, mid and low range sounds, the center dash speaker is a 3" speaker for midrange output and of course the tweeters and sub-woofer are for highs and lows respectively. Now if my 2017 is the same, that means my front door speakers are not outputting full range audio which explains why I am not getting the full spectrum from those speakers. This is all being driven by the Bose amplifier under the front passenger seat. I have come to the conclusion that I need to replace that amplifier and all of the speakers if I want quality full range audio for myself and everyone else in the vehicle. It is clear why the previous owner had the treble boosted to max as I imagine the factory 1" tweeters aren't that great. Now I need a wiring diagram for the radio HU and Bose Amp.

Ok, I am learning more and more about this Bose system amplifier Band pass to different speakers is controlled by the factory Bose Amp and it needs to be replaced with a programable amplifier. I've found the Kenwood P-XR600-6DSP is compatible with the 2017 Nissan Rogue With Bose System:

This amplifier and all new speakers would dramatically improve the sound. I'll just need to verify the speaker wire gauge to see what it can take power wise.
