Custom trunk for the 370Z
 

Here is my custom trunk i jist finiahed building. Turnaround- 1 week.

Intro: It's crazy how much you can get done with time on your side, patience, and a little knowledge to feed the brain. I started to follow through with this idea to build a custom trunk floor for my sub and add extra components and tweeters to the rear last Friday (7/31).

One week later, with a lot of hard work and determination, the project is about 90% complete.

What's left: I now just need to spray foam and dynamat parts of the trunk for added insulation and sound dampening, a new 10" sub, a mono amp, a dedicated battery (optima yellow top), capacitor, and a wiring kit to complete the installation.

I wanted to keep this custom build clean. Of course there are some slight imperfections but i always learn from my mistakes and will perfect my craft. Thanks to @harringtonkevin for the initial help in organizing the maze of wiring i once had. Wiring the third time around was truly a charm��

- capacitors and power distribution block
- LED lighting



If anyone is interested in something like this, feel free to PM me.

Thanks.

Looks clean

Thanks bro. wanted to keep it that way.

Looks great!

Do you still have the spare in there?

So is there a box or just a baffle...?

The spare is out.

Tested the sub in the trunk space without a box..it sounded alright surprisingly. But i will be building a box sometime next week.

My only regret is not having the amp recessed..ugh..I'm itching for a redo lol

Looks good! I'm actually doing a full custom trunk right now. All the panels are being replaced with fiberglass, and 2 12" subs. I wanted to go with something more similar to your design, but I know I'll toss something back there and puncture the sub, even with a grill.

right on!! I started a new build today. Trying to do a little different design with the amp, mids and sub recessed a bit.

My rear deck
 

I custom made two panels that fold together to include my amps and sub, but I may be evolving this look in the future. I will include some night pictures soon.

love the recessed look!! looks clean too.

Here is the night version I promised

SICK! going with blue as well or a multicolor leds.

Refined prototype
 

As promised, I decided to learn from my mistakes from the prototype I built 2 weeks ago or so. He are some teaser pics of what is to come.

- dynamat the trunk (only thing left is the door)
- wrapped my 2 farad capacitor
- amp enclosure with cooling fan to be mouted flush into the false floor sitting atop the amp enclosure
- jl audio 300.4 amp recessed on the false floor
- multiamp wiring kit:

Listing
 

I am still working with good but older equipment, the Alpine 7977 is dated but a expensive unit in its day, I added a Pioneer digital sound processor to fill in the space and it helps curve the music. The two amps are pre 2000 Kickers [before they started producing them in China]. The 12 inch sub is a Kicker comp. and I am running Boston Pro’s 61/4’s with bigeye tweeters at ear level {base of the A-piller}. The tweeter mount was critical, I tried the factory dash mounts and didn’t get enough reflection off the glass. If I didn’t have the existing equipment I would of put two 8 inch subs closer to the brace bar and used Focal separates instead of Boston even though I have always liked the bright sound of the Pro’s.

Right on! Regarding the tweeters: my POLK MMs provided plenty of sound reflected at the factory dash mounts so no complaints there. The components though do not provide enough bass.

Tweeters: Even though the tweeters at the factory dash mounts sound great, I added two additional tweeters (POLK DB) positioned at the center of the rear strut tower brace- it gives a nice balance in sound. (see pic)

As for sub, for now I am sticking with my Kenwood typhoon 10" sub. I will replace to a 12" shallow mount JL later.

I am receiving my MB Qart 1500.1 mono amp (West coast customs Edition) and Kicker 40CS654 bass drivers tomorrow. Then the wiring begins! Hope to have sound by the end of Wednesday.:happydance:

Update 9/4/15
 

I am happy to report that i am done with my audio/video project.

Decided to go with an alpine MRV-F300 and ditch my Jl audio (blown channel). My momo amp (or "sub amp") is an MB Quart 1500.1 amp. For a sub, i went with digital design audio- i am very much impressed by this sub. The quaility of the build is top notch. Checkout ddaudio or come check it out in my trunk for an in person review bc w.e. i post in words will not do it justice.

Assisted with a Rockville 2 farad capacitor.

Leds are wired to subs and bass drivers and turn on when via bass hit.

So far, the sound is great without tunning frequencies, etc.

Check out the latest pics. Youtube vid of the leds coming soon! If anyone is interested in this setup or a variation of it PM me.

Youtube video as promised. Cheers!

I am running the Alpine MRV-F300 also :tup:

Thats what's up! So far clean sound. I like how compact it is. I have to relocate it though- i mounted it right behind the driver seat along with my equalizer but the space is just to tight...

I just bought a MRV-M500 for two 8" Image Dynamic subs also. Should be plenty loud for my old *** lol :tup:

Nice bro! I think i am going to add 2 extra - either 6.5 or 8" ddaudio subs to complete the build but so far inoressed with just the 10 and i have not even tuned yet

Nice work on your audio system,they are a work in progress with different leveling off periods
