Ok people....It seem no one on this forum ever documented a full custom install for a Infiniti Q50 with the Bose Audio system. So here is a run down of what the system will consist of.
i plan to stay with the factory Bose Radio then run signals to a JL Fix 82 which will provide a balanced stereo signal to a Helix Dsp.3 processor . The processor will feed signals to two Zapco Z150.4ii amps.
.The first Zapco Z150.4ii amplifier will Power the Audio Frog GB10 and GB25 mids which will be installed in a custom A Pillar.
The second Zapco Z 150.4ii first 2 channels will power two audiodevelopement w800neos 8” Midbass drivers in the front doors and the other 2 channels will be bridged to power a single GB10D4 subwoofer....
I might do a custom fiberglass enclosure or just go infinite Baffle....That’s still up in the air with my installer.
i will post pictures of the entire install :)

Day 1 of the install officially started today...

The defrost vent on the A pillar might have to be bypassed to accommodate the mids and tweets.

267101

panels already removed in the trunk area...Thinking about upgrading to a shallow mount 12” sub instead of the GB 10” sub.

Looks great so far. I really wanted to pick up one of these when I was looking at cars a few months back. Ended up with an Accord coupe v6.
Fitting an 8inch in the stock location would be awesome.

Day 3.
Hit a little snag in the install. The midrange had to be installed in the dash instead of the A-pillar because of the location of the airbag safety strap. So only the tweeter will be fabricated to fit in the A-Pillar

267270

A-Pillar will now only house the GB10s



267271

First layer of Fiberglass for the Sub enclosure.



267272

Only one layer of Deadener for the rear doors because I decided not to go with any rear speakers.

267273

3rd layer of fiberglass added....

DAY 5.

The project just hit a huge snag....The original idea of placing the amp rack in the abandoned spare tire well had to be scrapped because we would increase the floor height to 3.5”...I travel a lot and luggage space is important and I am not just ready to give that much space...So plan B is to move the amps behind the seat and build the Processor rack in the spare tire well...

267571

Speaker Rings fabricated to house the 8” mid bass drivers.


267572

Speaker Plates completed.


267573

So the problem with the old amp placement will cause me lose way too much trunk space because the cover for the amp rack would take too much height....😩

267578

So new Amp placement will be right behind the back seat. Then the second lower level would be for the processor rack and distribution blocks. 🤞

Do you know for sure you need the Fix? I've worked on Bose system Nissans all the way up to 2013 Infinity and they all had a good signal coming from the Bose HU. All the factory processing was done at the amp.

The install is looking good so far.

seems crazy to me that you wouldn't utilize the factory 10" opening in the rear deck to house either a better aftermarket IB 10 or build a mount below for a larger sub.

A 10” IB was definitely an option....that rear deck was quite thin and the cost associated with building a panel to give it support was not really worth it...Plus I heard some IB woofers Before and I did not like the sound.....

DAY 8
Today was a lazy day since it’s a Sunday...All that was done today was the Neos were mounted and wired up to the baffles. Sound deadener was added to the headliner.

267818

The top cover for the amp rack was fabricated. It came out real nice and is a tight fit to the corners of the trunk.


267819

Gb25’s Wired up and ready to be installed.


267820

A stinger Circuit breaker was added because there was no space for a Fuse Holder.


267821

Headliner removed...Went ahead and disconnected the 2 microphones that calibrate the dreaded Active Noise Cancellation that comes with the factory Bose system.

267822

2 Layers of Kilmat added to roof.

267824

Neos installed and wired up the baffle.

267825

Back of Neo...
