Another quick update. Got the Audiofrog GS25 midranges installed. Just did left and right since I’m not going to tuna. Center channel. You can see I’ve mounted them on 3D printed PETG mounts using the ones that Travis Llado designed.
The connectors used are form Amped garage and were a perfect fit. The wire they use is also excellent.
First impressions are amazing. These mids paired with the tweeters are so clear and clean. I can’t wait to hear what the GS60 woofers add to the mix.

Tonight’s adventure is soundproofing the passenger side door. I took about 4 sq feet of dynamat extreme and dampened the inside of the door down on all thinner outer door pieces. I also struck butyl rope between the crash bars and the door skin. I also applied dynamat to the back of the plastic piece that covers the large opening in the door.

After the dynamat was applied, I moved into applying Resonix CCF7 closed cell foam. It’s kind of an ugly job but it works really well. The adhesive is insanely good.

basically to do this you have to take the door panel off and unplug all of the wiring. It’s a real pain. The next step is to put some dynamat on the large plastic pieces on the back of the door panel, tape down all the retaining pop clips with fabric tape and reinstall. Doing the “knock test” shows that the door is quite solid now. Honestly it wasn’t too bad to being with.

Looks good. I started Matting mine and wiring it yesterday. What do you have planned for remote turn on?

I'm actually not doing remote turn on since my Helix DSP does line level source detection, it works perfectly. I probably would have done remote turn on if I had gone with the penthouse for power using the resistor/relay modifications. However, I didn't like a lot of things (mainly safety/fire concerns) about that setup, so I'm running power straight off the battery under the hood - no problems at all.

So some more quick updates:

I still need to tune and dial everything in, but so far things sound really good even with just the crossovers only loaded into the Helix V Eight.

I also decided I want to give a 12" sub a try, so I have a Stereo Integrity SQL-12 now on hand to play with. I'm going to see how I want to enclose it and go from there.

Here's a picture of the SI SQL-12 installed. Built a quick 15 x 15 x 12.5" box, put some carpet on it. So far it sounds amazing, super clean. Haven't tried to get it super loud yet but I'm sure it will. I figured I'd try the box like this for now until I figure out if I want to stay with the 12 or the 10, and then maybe have someone custom build me a box for the trunk well. I realized that I'm terrible at carpeting skills.

Some more updates! Decided to change things up quite a bit, and did the following:

Got rid of the Helix director and mounted a Helix Conductor knob and Amazon Echo auto in an aftermarket center console tray using my own designed 3D printed mount. Conductor is great because you can control up to 4 volumes (Main, Subwoofer, Aux in 1&2), change which tune you're using and more.

Sold the the 10" HAT subwoofer and picked up a Stereo Integrity SQL-12, which has amazing SQ and can also shake the car good in just a 1cu foot box!

Got 3 AudioFrog GB25's which are going to go in the front dash, and I'll install the GS25's into the rear parcel shelf instead.

Got a pair of Stereo Integrity TM65 MK3 midbass drivers to try out in the front doors vs. the GS60s.
Attached are some pics.

That's a great update!!! Ironically enough, I'm trying to decide to stick with the 12TW3's or to get a pair of the SQL-12's or a single SQL-15.

I also want to know what you think of the Conductor. I've got a Director but have struggled with where to put it.

I think the choices you made on speakers will yield great results. I've used (and plan on using) TM65 Mk2's in my install.

@Lashlee So far I absolutely love the conductor. Makes it easy to do everything I need to do with it vs. the director. I'm running an optical cable today as well so I can have a straight digital connection for the iPhone, and I'll assign a volume color to the conductor for that as well.

Nice, sounds like you're running a lot of the same gear. The TM65's should be a perfect fit with the 3D printed mounts I used.

I'm impressed with how well the TM65's did in the last install (they replaced a set of ML1600's) so that's settled. The 3d printed mounts I had printed will need to be modified slightly to fit the size of the magnet in my setup (which I think Nick changed on the V2 to V3).

I may have give the Conductor a serious look, especially considering I'm looking at either the optical option (I do have a 12v converted airport express for airplay) or getting one of the BT cards to fit my DSP Pro. I am curious why more people aren't on board with the BT card option for ATF processors. I know Mosconi installs generally use the AMASS for direct BT connection...
