G35Driver - Infiniti G35 & G37 Forum Discussion - Thought I'd share my latest G37 Project with you guys :)

Just finished this G42S Sedan :) Goal here is maximum SQ in a show car...

here is a direct copy and paste from my post on diymobileaudio.com.

-------------------------------------------------------

Hey guys,

Just finished this project, which wins the award for longest distance between the owner of the car and myself :) -- Vehicle is out of North Carolina :)

Just it happens, he had the car down in Socal at GTM for a full 4.2 liter stroker motor build plus super charger install, and in between the motor and the SC, he had it shipped up to me for the install.

Lets get started with the goals:

1. To achieve a high level of sound quality, unlike most of my other customers, this car is NOT going to be a daily driver, so we sacrificed steahiness for utility for sound quality.

2. Remove the previously installed system and utilize the existing subwoofer with new equipment everywhere else.

3. Obtain a clean and classy look that goes with the exterior of this show car...Here the owner had two basic requirements: A. Be subtle, clean and simple, he did not want over the top cosmetics, and B. Display the beautiful Focal sub magnet up.

So...thats basically it, the end result is a car that is going to have MEGA horsepower, looks great at car shows, AND possess superb sound quality all at the same time. :)

First, three pics of the car from the owner, the car was shipped to me on stock rims and no front bumper (to get it on the truck), so i will use these instead...truly a clean looking ride here!

http://simplicity.elitecaraudio.org/c423.JPG

and here is the previously installed system, whcih had the focal 33kx sub and an audison 5 channel amp (already removed in the pic) along with a bitone and a focal k2p 3 way...not the worst i have seen but we both felt that it didn't live up to the rest of the car, the peeling vinyl didnt help.

http://simplicity.elitecaraudio.org/c424.JPG

Lets get started, since its just the stock headunit, i didnt take a picture of it...so lets start with the Mosconi RTC remote bass knob that i built into one of his blank knockout panels to the left of the steering wheel:

http://simplicity.elitecaraudio.org/c425.JPG

four quick pics of how this was done, first this is the Mosconi RTC with its box:

http://simplicity.elitecaraudio.org/c426.JPG

this was taken apart, and we will retain only the main circuit board unit:

http://simplicity.elitecaraudio.org/c427.JPG

This part was then secured to the knockout panel, with its internal plastic ribbing groundout, and voila, here it is:

http://simplicity.elitecaraudio.org/c428.JPG

http://simplicity.elitecaraudio.org/c429.JPG

Moving onto the front stage. We went with a set of Focal Utopia Be No.7 active set. and the midbass driver went into the stock lower door location.,

Here is the door which had been previously sound proofed with a layer of damper:

http://simplicity.elitecaraudio.org/c4210.JPG

So i added another layer of CCF over that:

http://simplicity.elitecaraudio.org/c4211.JPG

Adpter baffle rings were made up out of MDF and coated with spray on bedliner:

http://simplicity.elitecaraudio.org/c4212.JPG

They were then secured to the factory mounting bracket with OEM bolts:

http://simplicity.elitecaraudio.org/c4213.JPG

http://simplicity.elitecaraudio.org/c4214.JPG

The focal drivers were then installed and wired up:

http://simplicity.elitecaraudio.org/c4215.JPG

http://simplicity.elitecaraudio.org/c4216.JPG

The finished assembly was then bolted to the door using OEM hardware:

http://simplicity.elitecaraudio.org/c4217.JPG

http://simplicity.elitecaraudio.org/c4218.JPG

The same procedure was repeated on the driver side (yeah i know i did the passenger side first this time, variety is the spice of life right? lol)

http://simplicity.elitecaraudio.org/c4219.JPG

http://simplicity.elitecaraudio.org/c4220.JPG

http://simplicity.elitecaraudio.org/c4221.JPG

From past experiences with the newer G sedan, i know that the doors arent too bad with resonance, so i put down a layer of damper around the area of the spekaer:

http://simplicity.elitecaraudio.org/c4222.JPG

http://simplicity.elitecaraudio.org/c4223.JPG

Moving onto the rest of the front stage. We debated on going with A pillar stealthy mold versus a more on axis dash pod, and in the end, we decided on the latter for the best sound quality. it wasn't an easy mold since there isnt a lot of room on the driver side with the motorized steering column shroud, but in the end, i got it done.

Here they are, each pod houses a set of the Utopia Be Midrange and Tweeter, wrapped in dash matching black vinyl and aiming across at the opposite listener:

http://simplicity.elitecaraudio.org/c4229.JPG

http://simplicity.elitecaraudio.org/c4230.JPG

http://simplicity.elitecaraudio.org/c4231.JPG

here is the front stage as a whole, and my lame attempt at an artist shot by going black and white :)

http://simplicity.elitecaraudio.org/c4232.JPG

And here is what they look like with the grilles in place:

http://simplicity.elitecaraudio.org/c4233.JPG

http://simplicity.elitecaraudio.org/c4234.JPG

http://simplicity.elitecaraudio.org/c4235.JPG

A few build pics of the pods...

first, both sides were heavily taped off and a 10 layers of cloth went on for the initial mold. that was a MAJOR pain in the butt due to the steeply ranked windshield and the fact that on the driver side, i cannot exceed the partition between the dash and the shroud...but 5 hours later...here they are:

http://simplicity.elitecaraudio.org/c4236.JPG

http://simplicity.elitecaraudio.org/c4237.JPG

http://simplicity.elitecaraudio.org/c4238.JPG

once they cured, they were removed from the car:

http://simplicity.elitecaraudio.org/c4239.JPG

and trimmed to the desired shape, note on the driver side it follows the contourt of the dash/shroud partition:

http://simplicity.elitecaraudio.org/c4240.JPG

http://simplicity.elitecaraudio.org/c4241.JPG

rings for the midrange and tweeter were made out of 3/8" mdf, and low heat plastic flush mount boarders were secured to them, and then the two rings were joined together:

http://simplicity.elitecaraudio.org/c4241a.JPG

http://simplicity.elitecaraudio.org/c4241b.JPG

Then they were carefully aimed and secured to the base mold:

http://simplicity.elitecaraudio.org/c4242.JPG

http://simplicity.elitecaraudio.org/c4243.JPG

Grille cloth was then pulled across the shape, resin applied, and allowed to cure...then a duraglass/resin mixture was poured into the inside to strengthen them:

http://simplicity.elitecaraudio.org/c4244.JPG

http://simplicity.elitecaraudio.org/c4245.JPG

Filler was then applied and the two pods sanded smooth:

http://simplicity.elitecaraudio.org/c4246.JPG

http://simplicity.elitecaraudio.org/c4247.JPG

http://simplicity.elitecaraudio.org/c4248.JPG

Quick test fitment in the car:

http://simplicity.elitecaraudio.org/c4249.JPG

The interior of the pods received a layer of sound proofing to help with resonance:

http://simplicity.elitecaraudio.org/c4250.JPG

and they were wrapped in vinyl. I did the backside where its against the windshiled in a single piece, so it would look completely blended in behind the dark tint:

http://simplicity.elitecaraudio.org/c4251.JPG

http://simplicity.elitecaraudio.org/c4252.JPG

http://simplicity.elitecaraudio.org/c4253.JPG

The tweeters and midranges were then wired up and installed, with heatshrink at all the connection points, note Focal Blackhole stuff tucked into the pods, this material helps with reducing resonance and elimnating backwaves.

http://simplicity.elitecaraudio.org/c4255.JPG

http://simplicity.elitecaraudio.org/c4256.JPG

http://simplicity.elitecaraudio.org/c4257.JPG

and thats it for the front stage. Here are a few pics of the wiring bundles as they travel from the front of the car to the back, ziptied to the OEM loom every few inches and passing through the back partition wall via grommets:

http://simplicity.elitecaraudio.org/c4258.JPG

http://simplicity.elitecaraudio.org/c4259.JPG

http://simplicity.elitecaraudio.org/c4260.JPG

http://simplicity.elitecaraudio.org/c4261.JPG

http://simplicity.elitecaraudio.org/c4262.JPG

http://simplicity.elitecaraudio.org/c4263.JPG

http://simplicity.elitecaraudio.org/c4264.JPG

http://simplicity.elitecaraudio.org/c4265.JPG

http://simplicity.elitecaraudio.org/c4266.JPG

http://simplicity.elitecaraudio.org/c4267.JPG

Here are the bundles as they enter the trunk, against secured every few inches

http://simplicity.elitecaraudio.org/c4268.JPG

and all the signal related wires that are tapped into the OEM system (before the stock bose amp), led down the passenger side:

http://simplicity.elitecaraudio.org/c4269.JPG

The rear deck subwoofer was removed and area sound proofed:

http://simplicity.elitecaraudio.org/c4270.JPG

http://simplicity.elitecaraudio.org/c4271.JPG

Now to the trunk...again, the goal here is for simple, tasteful and classy...and after a lot of mocking up, i came up with a design that IMO fullfills those goals...its not over the top, but gives a nice overall cosmetic appeal to anyone looking at it :)

The new fake floor is wrapped in graphite alcantara, with two Mosconi AS200.4s upfront, whcih sends 200 watts RMS to each midbass, midrange and tweeter, as well as close to 1000 watts to the sub, the Focal 33kx 13" subwoofer is behind them, with a Mosconi 6to8 DSP on the left side, and a Connection SFD-41C combination power/ground block on the right side. all the components are trimmed in white vinyl. I chose the Connection block to give some cosmetic balance against the DSP on the other side.

Note all precise fitment of the flushmount around all the gear :)

http://simplicity.elitecaraudio.org/c4274.JPG

http://simplicity.elitecaraudio.org/c4275.JPG

http://simplicity.elitecaraudio.org/c4276.JPG

http://simplicity.elitecaraudio.org/c4277.JPG

http://simplicity.elitecaraudio.org/c4278.JPG

http://simplicity.elitecaraudio.org/c4279.JPG

http://simplicity.elitecaraudio.org/c4280.JPG

http://simplicity.elitecaraudio.org/c4281.JPG

http://simplicity.elitecaraudio.org/c4282.JPG

http://simplicity.elitecaraudio.org/c4283.JPG

http://simplicity.elitecaraudio.org/c4284.JPG

http://simplicity.elitecaraudio.org/c4285.JPG

the car also has another party trick...here are two remotes attached to the key...they turn on a simple remote control switch that baths the trunk white lighting. 22 feet of hyper white LED strips from Oznium were used...and lets take a look at what it looks like in the dark :)

http://simplicity.elitecaraudio.org/c4286.JPG

All the edges around the openings glow:

http://simplicity.elitecaraudio.org/c4287.JPG

http://simplicity.elitecaraudio.org/c4288.JPG

http://simplicity.elitecaraudio.org/c4289.JPG

http://simplicity.elitecaraudio.org/c4290.JPG

http://simplicity.elitecaraudio.org/c4291.JPG

http://simplicity.elitecaraudio.org/c4292.JPG

http://simplicity.elitecaraudio.org/c4293.JPG

and I thought this was a rather unique view, looking back from the center arm rest access hole:

http://simplicity.elitecaraudio.org/c4294.JPG

onto the build pics...first this oddly shaped enclsorue of about 1.5 cubic foot was made up, and secured into the car with the OEM spare tire tie down bolt:

http://simplicity.elitecaraudio.org/c4295.JPG

http://simplicity.elitecaraudio.org/c4296.JPG

http://simplicity.elitecaraudio.org/c4297.JPG

this is the platform for the amps:

http://simplicity.elitecaraudio.org/c4298.JPG

http://simplicity.elitecaraudio.org/c4299.JPG

this is the top portion of the subbox, whcih is another .15 cubft:

http://simplicity.elitecaraudio.org/c42100.JPG

installed into the car along with the side support platforms for the dsp and the dblock:

http://simplicity.elitecaraudio.org/c42101.JPG

http://simplicity.elitecaraudio.org/c42102.JPG

here are the individual support platforms for the dsp and the dblock, each spaced up accordingly to be level with the top of the amps and the subbox:

http://simplicity.elitecaraudio.org/c42103.JPG

http://simplicity.elitecaraudio.org/c42104.JPG

Here is the main amp/sub trim piece before and after vinyl:

http://simplicity.elitecaraudio.org/c42105.JPG

http://simplicity.elitecaraudio.org/c42106.JPG

the two side trim pieces before and after vinyl:

http://simplicity.elitecaraudio.org/c42107.JPG

http://simplicity.elitecaraudio.org/c42108.JPG

and all three pieces secured to the car:

http://simplicity.elitecaraudio.org/c42109.JPG

Here is the main floor piece before and after alcantara:

http://simplicity.elitecaraudio.org/c42110.JPG

http://simplicity.elitecaraudio.org/c42111.JPG

Three pieces of plexi borders were made up and clouded over:

http://simplicity.elitecaraudio.org/c42112.JPG

they were then secured to the underside of the pain floor piece via epoxy and screws:

http://simplicity.elitecaraudio.org/c42113.JPG

a layer of HD clear doublesided tape went around the entire outside board of the plexi rings: (the yellow is backing before it was peeled away)

http://simplicity.elitecaraudio.org/c42114.JPG

here is what they LED strips look like, just imagine this, except one run of 14 feet and 2 runs of 4 feet:

http://simplicity.elitecaraudio.org/c42115.JPG

once the strips were attached to the outter borders, a layer of black duct tape went over them to prevent light leaking out from the sides, the wires for the led strips were run to the approapriate point and a set of female quick disconnects went onto the ends.

http://simplicity.elitecaraudio.org/c42116.JPG

http://simplicity.elitecaraudio.org/c42117.JPG

and thats the main floor done ready to be put into the car:

http://simplicity.elitecaraudio.org/c42118.JPG

http://simplicity.elitecaraudio.org/c42119.JPG

and here are the two side pieces before and after alcantara:

http://simplicity.elitecaraudio.org/c42120.JPG

http://simplicity.elitecaraudio.org/c42121.JPG

and finally, i finish up with some wiring pics of the trunk:

http://simplicity.elitecaraudio.org/c42122.JPG

http://simplicity.elitecaraudio.org/c42123.JPG

http://simplicity.elitecaraudio.org/c42124.JPG

http://simplicity.elitecaraudio.org/c42125.JPG

http://simplicity.elitecaraudio.org/c42126.JPG

So...how does it sound? quite frankly i am BLOWN AWAY...

the stage is nice and high with a very solid center image. the width is pillar to pillar and the depth is beyond the windshield.

tonality wise...here is the curve i got after just 30 mins of playing around...moving a total of maybe 10 bands across all SEVEN drivers...

http://simplicity.elitecaraudio.org/c42127.JPG

its very pleasing to listen to, spectacular detail and midrange resolution, midbass is nice and solid with good impact and the subwoofer blends quite well.

I plan to spend all day tomorrow playing with it so i have even higher hopes for the end result.

anyway, a good way to finish on a high note so i can go on my vacation to San Diego in a few days!

Cheers,

Bing
