I can still remember a time when all i seem to do are G35s and 350Zs....before I started getting all sorts of other models of cars...so it was kinda nice to return to a car i am intimately familiar with after an almost year long hiatus. Counting simple HU installs, this is about the 40th G35 I have worked on.

Note that this is not a G35 but a G42, reason being that among other mods, this vehicle's engine has been with a fully custom built motor that is right around 4.2 liters...for now its NA making over 300 to the wheels, but right after the install, its going in for a Supercharger and should be well over 600WHP.

This car also is extremely well sorted out, using very good and unique components and recently been repainted by my man William at Williams autobody in San Mateo.

Anyway, lets get started with the goals:

1. To achieve a high level of sound quality and can get loud enough over the powerful engine

2. To build a fully stealth fake floor that is also strong and durable since the car hauls around golf bags

3. To have a lil tasteful flash built into the install to go along with the clean and understated look of the exterior.

so here goes...first a pic of the car, IMO this is one of my favorite modified G couples I have ever worked on, its done extremely cleanly, no huge wing, no tons of gills and vents, just clean and classy, i also like the wedssport wheels on it...a nice departure from the normal, which is volk volk volk Just overall very tasteful but underneath, a ton of very high end mods:







onto the system.

The signal starts with a customer supplied Sony XNV-770BT double din navigation equipped dvd headunit, installed via a JDM finisher. its a nice and clean unit with a very clear screen, about the only thing i dont like about it is the huge thick front face...which coupled with how tight it is behind it in the dash, makes it hard to flush mount. Not to mention if its recessed too much, the face can catch on the opening on its wing down motion.

One challenged i had to work around was the slew of monitors, sensors and their accompanied cable already installed into the car, including a huge bundle behind the dash...but in the end, i managed to get everything to fit...here is the shot of the dash with everything lit up:



The customer also supplied me with a Sony XA-R800C backup camera, which i put into the back above the license plate, really the only place on a G coupe since the lights are recessed into the bumper:





The car uses a JBL MS8 for signal processing, and i installed the display unit in the glove box, along with an extension cable for the tuning mic and also the removable sony/tomtom navigation module:



The front stage is my old trusty Seas Lotus Reference 6.5" two way component. The midbasses were installed into the stock lower door location.

First, the door was sound proofed and new wires run through the molex plug into the door:



Next two adapter spacer rings were built and coated with truck bedliner to protect them against the elements:



The spacers were then bolted into the car:



The Seas midbass wired up and identified by color coded heatshrink:



and installed into the door:





The area on the door card around the speaker were trimmed down and covered with deamplifier pro to prevent buzzing:



And the procedure was repeated on the passenger side:













The Seas tweeters were as usual, molded into the A pillars off axis, and covered in dash matching black vinyl. It is almost impossible to match the flocked on finish of the stock A pillars, and matching the dash has worked well for me:









Here are the build pics of t he A pillars.

First the entire pillar was coated with a layer of resin, this hardens the stock finish and provides a solid foundation to attach mold cloth and filler to. Two rings were aimed and attached to the pillar, with a corresponding hole drilled in the plastic:





Grille cloth was pulled on the shape, secured at the edges with CA glue, resin applied, allowed to cure; excess grille cloth trimmed. and a mixture of duraglass and resin was poured with a squeeze bottle into the inside cavity of the mold to make it virtually a solid piece:



A layer of filler later, they were smoothed out and ready for upholstery:



Black vinyl was then wrapped across the shape:





and the Seas tweeters installed and wired up:







Next are a few pics of the bundled wiring...hard to see but I figured since i took em, i might as well post em













I also wired up his sensor array monitoring various key elements of the car, all underneath the passenger side carpet, where it is out of sight but within easy reach:



The rear deck 6x9s were removed for better bass venting into the interior, and the rear deck cover was covered in CCF to prevent buzzing against the metal deck:



now onto the trunk.

As stated, the goal wasnt to be overly flashy, but rather stealthy, durable and tastefull done. So here is the view with the stock trunk mat in place, 100 percent OEM appearance:



pop off the carpet and you see a new fake floor finished in durable graphite carpet, chose instead of vinyl for its resistance to scuffs and scratches. two cutouts are in the middle...the front one looks darker simply because of the angle of the light, they are identical colored:



Pop off the covers and here is what you see, its hard to get the entire install in one pic because of the small trunk opening.

but a single SI BM MKIII sits in a .5 cubic foot sealed enclosure upfront; in the back, the MS8 is sandwiched by a pair of Mosconi AS amplifiers. An AS100.4 sends 100 watts RMS to the tweeter, and 500 watts RMS at 2ohms bridged to the subwoofer, while the identically sized AS200.2 powers the midbass with 200 watts a piece. The MS8 powers the stock rear side speakers for surround left and right.

all the equipment is framed in blue vinyl that has a slight greenish tint to it, pretty much the closest thing i can find to the exterior color. and everything has been flush mounted with precise borders around all the equipment:

 

Now for some build pics of the trunk.

Here is the bottom half of the sub enclosure, with support bracing:



with the top in, hole cut, and wires passed through:



and topped with blue vinyl:



here is the main amp/processor support piece, with spacers and mounting holes:



Here is the main cosmetic trim piece before and after vinyl:







and installed into the car:



Here is the top floor center piece before and after carpet:





The two side pieces before and after carpet:





And the top covers, with grille mesh attached and carpeted:







And finally, i leave you with a few detailed shots of the wiring organization beneath it all













So thats it, the customer just picked up the car...overall the sound is VERY pleasant, powerful midbass, smooth midrange and highs...center with the ms8 sans a center channel, is a lil diffuse, but we plan to work on it in the future with more autotunes. the best part about this particular car was its subbass, i think a single BM, given its optimal enclosure size, is really perfect in this car, very smooth and linear extension, no bumps and can get really loud...i just wish i can get my hands on more of these

anyway, time for a mini vacation, be back with the next car in a coupla weeks.

cheers,

Bing

 

Nice build! Love the car! Haha jk, thanks again Bing.

 

By the way, anyone who is hesitating to do business with him.. don't. Very pleasant guy to deal with and the crafmanship is nothing short of excellent.

 

Wow awesome job with the audio and the car looks sick with the weds.

 

bing does awesome work

 

Holy crap, that looks awesome!!!!! I'd be afraid to ask how much that install was. Great job Bing.

 

Not as much as you would think. I originally was going to just get some sound proofing and HU install but was pleasantly surprised. Sounds much better but I just got to work on my exhaust now to enjoy it a little more when cruising.

 

My favorite shot is this one:


Stealth FTMFW!

 

Awesome work as usual Bing!

 

Awesome write up... now you got me thinking about getting a stereo system!

 

Side note...did you ever get it on the dyno for a true set of numbers? What did it make? Im working on a custom stroker that im building myself and im curious as to what its going to put down being a NA...
