Time to start the new build thread. I’ve been looking forward to this upgrade, and equipment is starting to trickle in. I’m not an installer, far from it. I can certainly do basic things, but the knowledge needed to pull off a quality build surpasses my skill set. I’m not the least bit ashamed to admit this…this is why we have great professionals like the many that post here on DIY regularly. That being said, I’m taking vacation and will be at the shop from open to close throughout the build, and helping as much as possible. I’m most interested in learning more about quality electrical layout and tuning. My local shop is excellent (average tenure of installer is about 20 years). I’ve known the owner for about 25 years and he’s a close friend. This will be at least the 8th full build he’s done for me. This will be the best “vacation” of my life. 😊

Vehicle: 2016 Ram Crew Cab 1500 4x4 Big Horn. There’s nothing fancy about the truck, but I love her. Exterior is basically stock. I added a leveling kit and slightly taller tires. Interior is stock, except the stereo. Windows are tinted dark. Along with this upgrade, I’m having the windshield tinted with see through UV tint and ceramic coated. I’m also adding a nice dash pad (would like suggestions on brands if you’ve used these before). The UV tint is primarily to protect my midranges and the dash pad is for SQ enhancement. The truck has 77,000 miles on her and I’ll never part with her. She’s all mine and a part of the family at this point. She’s my daily driver but may one day be retired to just competition use. I’ll let her be a “trailer queen”. Seriously though, I love my truck. 😂 Here’s a pic:

Current Build: I currently have Hertz ML 165.3 components in the front (tweets in dash and mids in door), ran passively, Hertz MP 6.5 coaxials in the rear doors, an Alpine Series R 12 under the rear seat (passenger side) in a Fox Box (ported). I’m using a RF T400X4ad running front and rear speakers and a RF T750X1bd on the sub. I used a JL Audio Fix 82 to integrate with the factory non-alpine uConnect 8.4 HU. Signal is sent optically to a JL TWK D8 for processing. The truck is sound deadened nicely throughout.

This has been an enjoyable system and my tuner knocked the tune out of the park. He was able to work magic, even with the SQ limitations. I’ve really enjoyed the Hertz components and the sub has performed well, again, given the limitations. I could not be happier with these small RF amps…never an issue, clean sound quality, and very impressive power from such a small footprint.

All of this will be going in my sons truck now. I used this fact to help talk myself into the upgrade.

Here’s a few pics of the current build:

I won a few of these competing MECA SQL competitions in the Street class with this very simple system. The magic is in the tuning! I made some new friends and had fun dipping my toe into the “competition scene”.

Great kit of gear and explanations! Subbed for this one. Can’t wait to see those K2 Ms.

I’ve heard the same, but after a few days to ponder on it, I’m not comfortable putting my $2,000 tweeters on the doors where they’ll get rained on. I just can’t do it. 🙂

I’ve been told that they’d be fine, but I’ll sleep better if they’re not getting wet as often as they would be down here. The tweets are inboard on the pods, and will be angled back toward the the driver’s seat a little. My tuner feels the tweets will perform just as well on the pillars as they would in the sails. Overall, the tuning will be much easier for him since he won’t have to deal with the midranges reflecting off the windshield. He went into a lot of science and theory (drew several diagrams even) that honestly went way over my head, but he seemed excited, which makes me excited! 😂

I guess we’ll see soon!
I know we have spoke offline about the challenges each situation and both can have nice outcomes. But if the angles of your dash, pillars and windshield are similar to my vehicle, I’ll be hard to convince that you’ll get the same end result (how it sounds and stages, not just how it measures) as I know just the change to mostly on axis tweeters made a really noticeable change to how my front stage sounded, despite it measuring the exact smart.

But again, I hate to muddy the waters when you have someone else doing your tuning and some of the work but if you have anyone close to you that has a truck/vehicle in either configuration, I’d try to hear it before you fully commit

I live in southeast Texas…we get our share of rain as well. I just keep a microfiber towel in the console and lay it on the sail panel if it’s raining hard. I knew going in I’d have to deal with it. I always said I’d never do kick panels either but here we are. lol
As far as windshield reflections with dash mounted mids…it’s just not an issue. Look at what Rick has been doing with his truck.
Yeah, I have to agree here, the corner dash location just provides too many advantages to me, especially with fairly insensitive mids like the 3.5wm/K2 m. You get tons of free output from corner loading (this is significant from 200-2000hz, like 6-7 db in my truck), much better response below 400hz from being mostly IB and even though they roll off (not really roll off, more losing the effects of the corner loading) around 2.2k, they respond to boost pretty easily up to 2.5k and the TBM won’t have any issuing crossing around there. Also they stage nice and wide.

short of going truly on axis, the dash location, in my opinion, is tough to beat.

Done. Full 3-way Utopia it is. No going back now. 😊
I know how you feel, I have a 3way utopia M on the way and currently have the Audison thesis as my setup 🤦🏿‍♂️
@UNBROKEN , what have we done?

I don’t think there’s anything better at that price point…and I’m not convinced even at a higher price point.
I have to agree there.

Tho I’ll probably have an Accuton mid / tweet at some point in a vehicle in the next 5 years.

Nick already told me he’s building my pillars to allow them to be swapped in the future lol.

ok, done. sorry to thread hijack.

The dash mats are used to cut down on reflections in the vehicle. They work.
I have one coming for mine - need to have it modded to fit around my dash pods but curious to see if it makes any substantial changes.

Where does one acquire one of these magical mats?
Dash Designs, Sedona Suede is what I ordered. @UNBROKEN said he tried a few and had the best luck with that manufacturer and model

Question…what does everyone think about squaring the amp rack side off? Instead of leaving the the corner open, the trim piece would be recut to cover both front corners. It would still be open underneath. See red line below. Thoughts?

I'd leave it. Any real estate in an amp rack is precious to me.

That area is 7 inches deep. There will be a floating rack that brings the depth to about 2.5 inches, with room underneath for wire management. This will bring the amps up almost flush with the top. The little nook would still be open, just covered on top. I’m thinking the HUB will fit there nicely, with the rest of the real estate being used for the three VXi amps. That being said, everyone still feel the same?
I still like keeping it open but it's your truck, not DIYMA's :)

Made it to MTI. This is my first time visiting their shop. Holy crap…it’s Disney World for car audio and hot rod geeks. The guys are really awesome and I was able to demo one of their many award winning installs. This was a momentous occasion as it was the first time I’ve had the privilege of listening to a true, over the top, SQ install and tune.

The bar has been set, and that freaking bar is extremely high. The demo by itself was worth the 5 hour drive. I will be back down here in a month for a tune by MTI. If nothing else, I’ll have a good A/B comparison.

Side note: JL ZR800s are the real deal! Damn son! I will probably upgrade to the Utopia 8s before the end of summer. I just thought I knew what dynamic mid-bass sounded like. Ha, I couldn’t have been more wrong. An upfront sub in the passenger footwell may be in the works also. The 10WM would fit there nicely. It’s like freaking magic.

A-pillar pods are in-hand and I couldn’t be happier with the final product. Simply beautiful. Now on to Wichita Falls, TX for tomorrow’s acquisition. 😁
Hell yeah man. Did you listen to Jeff’s car?

I hear very good things about that car. But I heard rumors he’s not running the c7 mids or tweets anymore.
I see why @RickWilson was rolling with spikes in his tires now. I made it to Decatur, TX tonight. Way too dangerous to keep driving north until the sun comes up. I had to use 4x4 the last ten miles or so. Traveled about 30 miles at 30 MPH. The roads are nothing but a nice sheet of ice up here. I lost count of the number of cars in the ditch. Nerves were shot when I finally walked/slid into the hotel. 60 miles to go in the morning. I’ll carry that enclosure back to Louisiana strapped to my back, while pushing the truck, if need be. 😵‍💫

Can't help but say I'm a little envious as your pods blend better than the GMC counterparts from the same company
I was gonna say, these pods play really well with this interior.

And man @saltyone , it's been a long time coming! So happy to see this come to life

Just plan on a retune after 50-60 hours minimum. Over 100 would be even better. The Utopia stuff takes a minute to break in and smooth out. @RickWilson can back me up on that.
100% on this. Mids and midbass changed quite a bit after about 2-3 weeks. They really loosen up, in a good way. But the midbass (at least the 8wm) was very stiff out of the gate. It had less more output than my 2 ohm BLAM for the first couple of days stiff. But after a few weeks, they really got way more musical but needed some gain pushed back into them.

After the 20 plus hours of tuning, maybe I won't need a retune. 😁

We're doing a couple different tunes in the truck, and trying to accomplish something close to true rear-fill with one of them. Hopefully, I'll have the truck tonight for demoing. Fingers crossed!
I'd say the Utopias need about 60-80 hours of break in to really open up but I would wait until you get a swing in temp/humidity during the summer months to get the re-tune done. It shouldn't be drastic but will be worth it with level of gear you know have.

Can't wait to hear your first impressions

Just iron it. Mine had some wrinkles in it that wouldn’t lay out…10 minutes with an iron and it’s flat as can be.
Good call - my mat has been rolled up on my other desk for about 2 months.
