just got done with an 2005 G35 coupe for a fellow forum member. Its a simple SQ build and we plan to compete wtih it in MECA, SQ only (no install), street class. starting at sacramento autorama this saturday

goals:

1. achieve a nice level of sound quality for daily listening and the occasional sq comp

2. to take up as little room as possible in the trunk since this is a daily driver

3. to create a look that is subdued but carries a little more flare than say just a plain carpet install


acutally, even though i have done quite a few G coupes, this one is somehwat unique, its acutally the first active SQ install i have done in one that still has all the product in the floor. with the other true sq setups, they all involve a side mounted box, and the ones that have it all in the floor have been just passive setups.

lets get started.

first two quick shots of the battery. even though adhering to install rules is not a requirement, i figured i will take two quick pics anyway.

first shows the 0 guage power cable, wrapped in techflex going into the cabin via the stock rubber grommet:



here is a shot of the 150 amp circuit breaker that protects the system, tucked next to the battery and within 18"



the signal starts wtih a kenwood 7014 dvd/nav double din unit, provided by the customre, and is installed via the JDM adapter plate and dual zone climate controller. the ipod cable comes out of the upper cubby:



as the car utilizes zapco tuning, here is the pic of the laptop plugged in and doing some tuning



the front stage consists of a set of seas lotus reference 6.5" two way components, and as usual, the door panels received a layer of foam damping with some normal proofing material near where the speaker mounts. a new baffle was fabricated, coated in truck bed liner, and new wires ran into the door via stock molex plug, here is the driver door:



quick shot of the termination at the driver side midbass:



and the speaker installed in the door:



a close up of the seas lotus reference 6.5" midbass driver:



same goes for the passenger side:









the backsides of both door cards was heavily sound proofed as well, as the stock door panel is definetly prone rattling and buzzing, this helps cure almost all of those issues:





the tweeters were molded into the A pillars...first, ring baffles were aimed (off axis facing each other), mold cloth pulled, and resin applied. when that cured, a duraglass - resin mixture was poured into the inside to make the pods solid:



then filler was applied and the entire thing sanded smooth:



they were then wrapped in black vinyl to match the dash:



and the tweeters installed:



and here they are, installed back into the vehicle, sorry for the dark pics:









the only remaining pic of the interior is the sound proofing of hte rear deck. what i have come to notice in the past, is that the majority of the rattles that eminate from a G35 coupe's rear deck, is from the cardboard rear deck cover buzzing, and also from it boucning up and down against the metal. to the point htat sound proofing the metal part does very little to help. what i have found is that a layer of foam helps greatly here, and this is what it looks like on the underside of the stock rear deck cover.

both rear deck speakers were removed as well for better venting into the cabin:



moving onto the trunk...as mentioned in the goals, the idea is to take up very little room. and here is the normal view with everyhting hidden, and it looks virtually stock:



pull off the carpet, and you see the center section fake floor with a gunmetal CF vinyl insert, with carpeted grilles covering cutouts.



lift those covers and the system is exposed. two image dynamics ID10 subwoofers is upfront, sitting in a sealed enclosure just below a cub foot. they are trimmed in black vinyl. the cutouts in the back showcase a zapco DC reference 650.6, whcih sends 180 watts to the midbass and 100 watts to the tweeter, and a DC reference 500.1, which powers the ID10s with 500 watts total. i also trimmed the stock under carpet to fit beside the fake floor that i built:







so here are some quick build pics..

this is the subbox / amp rack combo, prior to going into the car:



once that was secured into the car, the subs and amps were mounted and wired up, here are two pics of hte wiring:





and finally, here is the two piece top fake floor cover, first in bare wood:



and then trimmed in their respective vinyl:



so thats it, simple and straightforward, and it does sound quite good. similar to david's G coupe that competed all last year in iasca. it needs some more fine tuning but we hope to get some more feedback and make some adjustments at the MECA comp on saturday

cheers!

impressive work

question on all them pieces used in the trunk.

wouldn't they rattle like a **** with all that base in there?

 

i will let the customer chime in on that

but all of them are fully secured not an ounce of rattle from them. you can grab the amps or subbox and shake the entire car with it hehe.

 

Doesn't rattle at all. Haven't tried grabbing the amps yet though!

Thanks again Bing! Looking forward to Saturday.

 

i wish i had some one like you to do my install and recommend speakers and such

Clean install!

 

Beautiful install.

I'm going to have to print up those pictures of the doors for when I get back to my car to do my install.

 

sick work!

 

just letting you guys know, Ntrinsik took home first place in street class for Sound Quality in his first competition this past saturday in sacramento. congrats dude!

 

I would be that guy if you're in Texas! Check out my website for some past projects.

Awesome install By the Way!

 

Nice work as always Bing!

 

Ah man another G-35 with kenwood HU, Seas Lotus Reference, Zapco DC Reference amps & Image Dynamics Subs........ A WINNING Combo that WORKS!
