06 M45 14 spkr Sound Upgrade (w/pix)

Postby DeanM45 » Sat Jul 07, 2012 9:33 pm

Hi all,
I had tacked onto another thread but I am going to move my "build" over to this thread.

I went ahead and took the plunge today. I have the 14 speaker system and ordered the 62.9i kappa and 1031t tweeters. The sound is much cleaner than the stock setup, comparable to my Lex GS stock system. Lacks some mid bass but I am pretty sure it will sound better as the speakers break in/loosen up. I used the stock mounts with the bose speaker guts removed. Dynamatted the door and sealed the speaker and mount together and to the door frame.

Not pretty but solid as hell (rigid mounts are the best when trying to seal off a speaker). Use epoxy to seal any potential gaps between the stock Bose speaker mount and the new Infinitys. The speakers are screwed to the mount which is the primary method of attachment.

Image

The Dynamat is on the backside of the door panel, sorry no picture but not rocket science.

I am VERY pleased with the results. The new woofers give a good deal more bass (some is probably due to sealing the door up as well) than I thought but the real highlight is the tweeters on the upper doors. Much much better sound. On the co-axle woofers I have the tweeters at -3db and the imaging is really good.

I would like more "deep" bass so I pulled the trunk liners out and started looking around. Found out that I have a full size spare which was a cool find.
There is FAR more bass in the trunk than in the cabin (with the deck lid open) so that got me to thinking......there are NUMEROUS holes on the trunk skin, some of which must undoubtedly find their way into the cabin. In an infinite baffle (stock) system it is extremely important for the cabin to be sealed from the trunk.

Sealed up all the holes in the parcel shelf (the openings for the, I assume, base audio rear speakers were leaking badly. There is a cover on them from the top (much like Dynamat material) but it was not sealed well). Also pulled out the stock sub and used some weatherstripping to seal it better in the parcel shelf. Found a few more holes from the top that I could not reach from the trunk area. The rear seat "bulkhead" is pretty well sealed and did not need too much work. The ski pass through already has a pretty good weatherstrip type seal on it BUT you must seal around the plastic door flange. The ski pass through is on a "plate" that is bolted to the trunk bulkhead. Thinner sheet metal was used for some reason. I Dynamatted the plate and now it has a much more solid sound when hit with a mallet.

Pictures of the "sealed" trunk:

Image

The sound output is now vastly improved from the stock sub and I mean vastly. I used about 1/2 a roll of Gorilla tape , Dynamat and two cans of "Great Stuff" expanding foam. LOTS of trimming and sanding makes the mods pretty much invisible. It is a bit harder to close the trunk now and you can see the sub move (from the top of course) when closing the trunk which leads me to believe that most of the air leaks have been sealed.

Also, Dynamatting the center of the spare wheel well really helped to quiet down road noise (and exhaust noise). Really thin metal there:

Image


I went ahead and installed a Kenwood old school KAC 744 amp today to drive the door speakers. I used two Line Output Converters from PAC attached to the stock Bose amp outputs. Worked out REALLY well. Looking at the Bose amp in the car all of the door speaker outputs are on the far left connector. Pinouts are in the FSM. The remote for the Kenwood is on the far right connector, brown wire (only brown wire) on the far right.

The LOCs are on top of the factory Bose amp:
Image

I ran the power wire (4 gauge) through the bulkhead connector under the windshield on the passenger side. Ran stiff wire around the factory grommet down behind the glovebox (pull the passenger under panel off and you'll see the wire. Attached the power cable and pulled it up. Drilled a small hole in the grommet and poked the power wire through. Then to a block fuse and then the batter terminal. Went back and sealed the wire to the grommet with silicone (don't want any water dripping inside the cabin):

Image
Image
Image

Drilled a small hole in the lower trunk firewall , put a grommet in, and pulled the wire through:
Image

Not pictured but I also ran speaker wires under the front seat for if and when I install Aura Bass Shakers to compliment the sub.

So far, really happy with the sound improvement. The Kenwood really woke up the Infinitys (no real surprise there going from maybe 20 watts to 50 watts/channel. They put out a LOT more bass now even with the 20hz subsonic filter on.

Let me know if you have any questions.

Amp in trunk. Mounted it on the floor for now as I am still doing a few things and adjustments are far easier here, either from the trunk or through the passthrough:

Do you still have working bluetooth and other features after adding the Kenwood?

Yep, all functions are still there, volume lowers when voice command is used, nav and blue tooth. Only difference is the marked difference in sound output and quality.

Back seat is super easy, two clips that you pull out on the lower cushion (every car I have ever seen is like this) then 4 14MM bolts on the bottom of the seat back. Lift the bottom of the seat back while pulling towards the front of the car. Super simple.

OK, I've noticed even when stock that sometimes the front speakers rattle(others have complained about this as well). I Dynamatted the inside of the metal door panel so I figured that the rattle (which I thought the new speakers would fix but did not) could not be comming from the door. Pulled off the door panel, again, and went ahead and dynamatted the panel.

Picture shows the panel as removed
Image

Picture shows panel with the "map pocket" removed (it is just held on with screws).
Image

Last picture shows the panel dynamtted, without the map pocket reinstalled. I dynamatted both sides of the map pocket and screwed it back on.
Image

Rattles are now gone. Turns out that the majority of the rattle comes from the map pocket which is just super thin plastic that acts like a little resonance chamber.

The grommet behind the battery -- where the main harness goes through. Poke a hole in the grommet just to the side of the harness, poke all the way through. I used a long screwdriver. Then feed a stiff wire through the hole to the point that you can find it in the cabin, behind the glovebox. Attach your power wire to the end (in the engine bay) and then pull the stiff wire with the power wire attached into the cabin. I suppose it would help if you had another person to help you guide the wire topside but it can be done with just you.

Went ahead and installed the same speakers in the rear doors today. Picked up some FatMat which is a much cheaper version of Dynamat. Did the rear doors and back seat area. Really cut down on road noise. The rear speakers added a good fill over the stock speakers which I had running off of the stock amp---all door speakers are now on the Kenwood. It is really amazing how good the Infinity speakers are over the stock Bose/Infiniti speakers.Very happy with the way things are progressing.

08+ is a different amp and wiring. I'll look around for a wiring diagram but I have not seen one yet for the 08+ cars.

Odd, I can not get the wiring diagram to align with that connector. Just so you know, the stock amp just uses an acc feed to power on (it is always on when the ignition is in acc or run mode). You can back probe each pin until you find a positive voltage, turn ignition off and see if the voltage drops to zero. You can use that for your remote turn on.

On the sub, the black with silver should be negative.

thanx for everything.....i also figured the chart out....when your matching numbers and colors from the diagram....it connects into the actual amp UPSIDE DOWN!!!! so whatever it on the bottom ON PAPER, its actually on the top IN THE CAR.... i stayed up all night tryna figure it out...just found out a hour ago...will update on progress

so for a 2008 m35x w/ nav (8 speakers)....the BROWN WIRE on THE MIDDLE BROWN HARNESS(Top row) is the ACC feed to hook up your remote wire for your aftermarket amp....as stated on PAGE 276-278 ( http://www.nicoclub.com/FSM/M/2008/AV.pdf )

Ok how about throwing this monkey wrench into the situation, can you guys compare the harnesses between the 06/07 model years to the 08/10 model years, I am interested in possibly upgrading my dash to the revised mid model year refreshed blue and music box option. Or are we that lucky that it is plug and play.

Gauge cluster should be plug and play from what I have seen. Adding the hardrive music is a different issue because I am pretty sure you would need the "radio" from an 08+ as well as the hard drive and IPOD control "box".

Cool deal.
Do you still have the stock sub in place?

What are the box specs and did you build it or buy it off the shelf? I've had Orions in the past and sounded good in a sealed box but ported they were WAY too boomy for me. That size of box might work for me as well.

yes the stock sub is still there.....i bought it as package(sub,box and amp)...i paid pennies for it...some dude owned an audio shop that went out of business..his whole crib looked like the store....i was thinking about unplugging the stock sub to see how it sounds...but im very happy with...i do wish the box was ported tho

I was asking about the stock sub because if you remove it you will have a better pass through for the sound pressure into the cabin. Had to do that on my GS and it made a world of difference. Good find on the "kit".
