Also, I just noticed that in the specs of the MB Quart speakers:
- 4 ohms impedance

Make sure the speakers you get are rated at 2 ohm impedance.

I am looking at a set of Pioneer TS-D1602R rated at 4 ohms.

Would they work?

 

[assad]

Yes, they would work...

If you are using the stock radio which is rated at 2ohm, you won't be getting the full potential of the speakers. Also because of the mismatch in impedance, you might blow your speakers if you have the volume all the way up.
Check the spec of your radio as far as impedance rating, some can drive a wide range of speakers. But I know the stock speakers I replaced on my 2015 murano were rated at 2 ohms.
Check av.pdf for the specs of your radio.

If your radio is rated down to 2 ohms, you won't hurt anything with 4 or 8 ohm speakers. You will NOT "blow up" 4 or 8 ohm speakers with the volume all the way up. Higher resistance (4 vs. 2 ohms) means that you get less volume from a higher resistance speaker with the same input, but that simply means your maximum volume will be lower at 4 or 8 ohms than with 2 ohms.

If the radio is rated for 2 ohm speakers, you can use 2-4-8 ohm (most common ratings) with no fear of damage. Just don't mix them front to back, use the same resistance for all speakers.

 

[metrxseven]

It is the stock NON Bose radio.

So will the volume be much lower using the Pioneer?

 

[assad]

The amp inside the radio is the driving force here.

In theory, if you drive a 4 ohm speaker with a 2 ohm amp, you will not get the full efficiency of the speaker. For the same volume level, you will be delivering less power to the speaker at 4 ohm than the speakers at 2 ohm.

Hi all new owner of a 2017.

I was looking at the diagram that is in post #10....It shows the REAR speakers as coaxial....so if I was going to replace just the door speakers would this be correct.

Front---> 6.5 component. 2ohm
Rear----> 6.5 coaxial. 2ohm

Or all component?

I'm looking at the Alpine KTP-445u mini amp. It's supposed to run off the power of the factory head unit, so no additional wiring is necessary. What do you guys think? I have non-bose with navigation.

 

[assad]

The nissan murano radio has a 10A fuse (I think so, I can't recall for sure, please double check on the label attached to the fuse cover under the steering wheel), so if you do the math, the maximum power it can handle is 12vX10a=120W.

The alpine is rated at 45WX4 at 4 ohm, which is a total power of 180W max.

So the answer to your question is yes, you can power it from the head unit, but if you push the volume too high, it will exceed the head unit power rating, and you will blow the radio fuse.

If the amp has a gain control, you can lower it so that it will not exceed the power rating of the radio.

Ideally, after market amp should be powered directly from the car battery.

I once had my after market amp and subwoofer power by my head unit, since I was too lazy to power it directly from the battery. One day, I forgot the volume level was too high, when I turn on the car, I heard a loud boom, and noticed the fuse was blown. I replaced it and since then I am powering both my amps and sub directly from the car battery.

I've yet to see manufacturer (Nissan, Bose, whoever) that didn't use cheap paper cone speakers in their vehicles. I swapped the speakers out in my old Honda for Focal and it was a day and night difference. While the Bose system in the MO is OK (heard alot worse) there is quite a bit of improvement.

I'm not sure how much power is being driven from the head unit though to get into a speaker swap (without also adding an amp) or if there is any proprietary electronics attached to the speakers also. If anyone has any info on that I'd love to know.

For Focal in a MO, I know the pillar tweeter would need modification to mount. Also don't see a matching center. Not sure what the results would be just swapping the door speakers or those in the back. Could be better, could be worse.

 

[upinsmoke]

I'm still confused about the number of speakers and how they came to 11. Two door pillars, one center dash, two in the front doors, two in the back doors, and two speakers in the sub (tire). Where are the other two to make 11?

Remember, car manufacturer want to save as much money as possible, unless you buy a premium package or platinum which comes with upgraded sound system, you will get cheap speakers. The stock speakers on the murano (S,SV) are very cheap, I bet you can get them on ebay for $5.

I'm not sure how much power is being driven from the head unit though to get into a speaker swap (without also adding an amp) or if there is any proprietary electronics attached to the speakers also. If anyone has any info on that I'd love to know.

The speakers will not draw power directly, it will only respond to the power it is being fed by the amp. So if you replace your 45W speakers by 100W speakers, you will only be able to get 45W out of it, since the amp will only supply that much.

There is no proprietary electronics, as long as you match the impedance, you should be good, biggest factor is the amp, which I think is the most crucial part.

When it comes to sound, the sound quality will be affected by the weakest link in the chain (Source, Amp, Speakers), so to get the best sound quality you need to make sure all are in sync.

For Focal in a MO, I know the pillar tweeter would need modification to mount. Also don't see a matching center. Not sure what the results would be just swapping the door speakers or those in the back. Could be better, could be worse.

On the murano, the pillar tweeter will need modification to mount, but it is not that difficult, it will not be a perfect fit, as long as it is secure, the opening is large enough to fit any aftermarket tweeter. And once you put the cover on top, no one cans see it.

To get the most out of your sound, you will need to swap all 4 speakers, the center will not make that much of a difference. Most amp come with 4X channels + 1 subwoofer.

So Im about to replace all speakers in my car and sound deaden the doors.

It is hard to find budget friendly 2ohm speakers, any recommendations?
Also I want to replace dash speakers, are 4ohms OK?
Thinking about this [ame]https://www.amazon.com/GRS-3FR-4-Range-Speaker-Driver/dp/B00K2ESJZ2/ref=sr_1_1?ie=UTF8&qid=1498441354&sr=8-1&keywords=3+inch+speaker[/ame]

Also, is it possible to install central speaker by tapping into the existing speaker wire?

 

[JBDB76]

Just upgraded my speakers in a 2017.5 Murano with Navigation (not Bose). Found some DROK 3" 4 ohm speakers ($15.69 ea. from Amazon) for the dash. Not a perfect fit so be prepared to shave some plastic to enlarge the holes and remove the upward protrusions that box in the factory speakers. Also removed the female connectors from the old speakers and reused them on the new speakers. Connectors can be removed from the old brackets with some needle nose pliers and a little force -have to solder wires to new speaker but then can use factory connector. Faced new speaker connections toward front of vehicle and placed some soft Velcro (just soft side) on bottom of DROK Magnets to ensure the wires and connectors stay silent. Got two bolts to hold new speakers in (was 3).


Moved my attention to the doors and replaced all speakers with 6.5 "JBL Stage 602's 4 ohm (39.95 Pair from Amazon). Used adapter rings ($6.78 set from Amazon -had to cut a small channel to run wires to speaker connector) and Metra 72-7401 speaker connectors (4 ea @ $9.99 pair from Sonic Electronics- push onto speakers and connect directly to factory speaker plug-no soldering ).


Overall much better sound but don't expect this to turn the vehicle into a concert hall. For less than 150.00 I do think it was worth it. Also was shocked to find out that two sets of my factory door speaker surround bolts were not even hand tight from the factory -somebody needs to get with the speaker girl/guy on the assembly line). Would have likely been into the doors to find a noise within 6 months anyhow.

No matter how good your speakers are, you need a good amp to bring them to live, something that can push them to their limit. When I first changed my head unit (non-bose), the sound improved dramatically, even with the stock speakers. Not sure how good the bose amp is, but IMO only aftermarket amp can drive powerful speakers.

I also bought 2 component and 2 coaxial JBL GTO series speakers paired with a infinity amp, that I am about to install. Got a 12 inch pioneer subwoofer to go along with it also. Will see how it sound...

My previous kenwood sub is too muddy and does not give me that punch I am looking for. I am doing a complete overhaul of my sound system.

Wish I had found those metra connectors when I was first replacing my speakers. I had to cut them off during my initial install and solder them to be able to connect them to my infinity speakers.

 

[JBDB76]

Agreed Assad. Good luck with your projects. You prior posts did help me to confirm a few things before I started my speaker replacement task (thanks!). As for those Metra connectors, half the sites said it was not a fit and the other half of sites said it did. I was leery right up until they connected and I realized it was a fit.

Thanks for the info my friend. Taking a look at the doors it doesn't look that difficult. I was going to go with Focals for the doors and picked up two sets of the PS165F (2 way) but think I might get a set of the component 2 ways (PC165F) for the front instead. Whether I go with the stock position of the Bose speaker tweeters or modify the sail panel on the door I'm undecided. Also thinking about dynamating (or something like that) for the doors while i have the panels off.

Is the crossover for the tweeter / door panel speaker built into the tweeter? Thats the other big question I have about fronts. Or does it tie somehow into the other 3 dash mounted speakers for a bose system?

 

[assad]

Never heard about the focal speakers, but $500 for the pair?? WOW, pretty expensive.
You must be serious about your sound!!!

Component (woofer + separate tweeter) will sound better than 2 way coaxial. The placement of the tweeter in the murano is also pretty good, so I would use that location instead of other placement in the door.

The crossover is built in the tweeter, if you remove the stock tweeter, you will see a small cap right below it to filter the highs. This is the way it is for Non-Bose...

If you have Bose, I am not sure the location of the crossover...
One way to find out...you can easily remove the Bose tweeter and see if you notice anything attached to it, if you see a cap on the tweeter, then the crossover is built in, if not, then the crossover is somewhere else.

The stock tweeter location is big enough to hold most aftermarket tweeters, but you will have to do some modification to hold your own tweeter.

These are the ones I bought the front (Infinity Kappa component), I have a 4 channel infinity amp pushing them, and I can tell you they sound pretty darn good. And it's loud enough that I never have to go past 1/2 on my volume.

The rear is just to fill the sound, so I bought these coaxial from Infinity:
[ame]https://www.amazon.com/gp/product/B009GHQX5O/ref=oh_aui_search_detailpage?ie=UTF8&psc=1[/ame]

Here is my Infinity amp sitting right under the passenger seat. I have industrial velcro attached to the bottom, so they stick pretty well to the carpet and won't move a bit.

They are amazing sounding car speakers. I was familiar with their home audio speakers (which are also excellent). You can get them about 1/2 off if you shop around on ebay. I wouldn't put $1000 into speakers in a car, $500 is about my limit. I had focals in my Honda and the sound was amazing. Also taking into account I'm going to do it myself a huge savings from labor will be there.

I like how you used the material to act as the vapor barrier, I was wondering about that and seems a better way to do things. I'm going to get the windows tinted first in the front and after that wont need to worry about anyone getting into that space. Still have questions about the crossover for the bose equipped murano. Did the tweeter cover just pop out and give access to the speaker there? That should be an easy determination if that acts as the crossover and not someplace else. Also thinking I could maybe mount the new crossover in the door? IDK

Also have the stinking suspicion that the speakers are the same in the non bose compared to bose speakers.

 

[assad]

The tweeter cover will just pop out...
But you need to remove the headliner first, then pop out the cover, then the tweeter is held by 3 hex nuts. Don't use too much force when removing the headliner, it should come out easy; also be very careful after you remove the headliner not to touch the air bag in there.

You could mount the crossover in the door if they are small enough, that would be the best location. I had a hard time routing the speaker cable through the door, because of the big rubber grommet, I could not remove it, so I just place them by the amp and tap into the stock wires.
