Really nice build, man, this thing is going to sound great!

One question though, why were the threaded insert nuts screwed in from the outside of the sub enclosure's baffle??

Hmmm not sure....I know my installer was going to add a pressed grill to protect the subwoofer....I will ask for sure.

I would definitely ask him to put them in from the inside like they're supposed to be... It's great that he is using them vs. just drywall screws, but screwing them in from the outside is a mistake I wouldn't live with.

Day: I lost count :)

My installer decided not to send me any more pics:(. Since his shop is on the other side of town, I just had to wait until the big reveal. The install is about 95% complete....He is just finishing up the pressed grill and cover for the dsp rack. His first impressions without any tuning the subs and Neos sounded very good....The Mids and highs definitely needed tuning....He told me not to worry . I will be picking up the car today and will post final pics of the install and my overall opinion of the system.

Ok...First off all I need to give a huge shout out to Mr Tam Nguyen from SLA Acoustic in Houston for installing my system....The dude knocked it out of the park.....So the all important question is how it sounds. Compared to The stock Bose System , there is no comparison...
The GB Mids and highs are truly spectacular....I auditioned the Focal EX and thought the highs were a little too forward..The GB10s are very warm and not fatiguing at all....The GB 25 is breathtaking...I just can’t believe I am getting so much sound from such a small speaker....The Neos definitely put out some serious Midbass....The GB12 sub is just the right amount output for me...I am no bass head 🙂
The Helix Dsp is real nice...I was told not to mess with the settings....I will probably let the speakers break in before doing any future adjustment.
So after about 1 hr of listening to the system...It’s kinda weird it does not sound like a car stereo system like the ones I had in the past. It sounds more like a high end home theatre system. I played some high def tracks on YouTube and was blown away. Then played some normal stuff and it sounded ok..Also played some poorly recorded crap and also played the radio and was not impressed 🙂..So a badly produced track sound bad while a good recorded track sounds excellent....I guess garbage in garbage out....
I guess with time , I will have a better feel for the system.

Congratulations on getting the car back, the install looks very clean! I love what they did with the grills over the amps/crossovers. It could just be my eyes but the carpet on the sub enclosure looks a shade off from the floor/amp/dsp rack, otherwise I like!

It’s the same carpet...could be the lighting 🙂

I recorded a short snippet of how the GB setup sounds in my car...the track is from a group called InfectEd Mushrooms.

Love listening to infected mushroom, their music really sounds crisp and packs a deep hard punch! Crank that sucker and I'm all smiles. LOL. Gorgeous build by the way!

Appreciate the love bro...I was messing with the helix Dsp and I actually wanted to hear how low the NEOs Can go...I dropped the Neos to 50hz and the midbass extension went bananas....I think I am going to get with my installer and have him retune with me present to the types of music I listen to....
So far I have no regrets taking the Neos over the GB60s 🙂

Fyi... I scoped the factory Bose HU and at max volume I had 3.5V and zero distortion.

I also was able to use the pre amp signal wires straight into the Helix. I just spliced RCA's onto the front right/left pre amp wires in the trunk. So if you ever wanted to ditch the JL Fix you can.

My car is a 2013 G37S sedan w/ Bose NAV and 10 speakers. A pillar tweets, center channel, 4" mids and 10" midbass in the doors, two rear door speakers and a 10" sub in the rear deck. I'm pretty confident it is the same exact system in the Q's.

Just passing info along if you want to let your tuner know....
