After the noise treatments in the doors, floor, and rear of the Camaro, I turned my attention to the firewall. These vehicles have a tube that runs from the engine intake pathway to the firewall, with a diaphragm to isolate airspace but allow sound to pass through. The solution is to 3D print...

This vehicle is full of inexpensive, DIY acoustical treatments: https://www.caraudio.com/threads/2014-accord-sport-sq-build-keep_hope_alive.570687/

interesting feedback. The enclosure being the reason for the difference in upper bass response?

you're crazy and I love it

That's a good option.

Since I had to change the tires from summer to winter, I took advantage of the effort to acoustically treat the wheel wells, kick panels, and quarter panels. There is a small amount of sound absorption in the space between the quarter panel and kick panel. The passenger side has the...

I also took the opportunity to recover the knee bolsters since they are just hard plastic on the SS. I used Resonix Fibermat 25 for padding since it has an adhesive layer to stay put, then wrapped them in fleece fabric and secured with 3M Super 77. Not a pro job, and the driver’s side was...

Made a big push on Friday afternoon and worked till 3:30am on Saturday to have a completed Phase 1, ready to drive again! Treated the rear panels with CLD, closed up the speaker hole, and then covered them in Fibermat 45 I reinstalled all of the interior. No reason to show pics since it...

I took a unique path in order to keep the new wiring away from factory wiring bundles that can generate EMF due to the amount of digital signals that are present in new vehicles. While it is not a major concern is most builds, because I am making the car as quiet as I can, the electronic noise...

Using 14/2 CL3 rated speaker wire, I ran two pairs of 14/2 and 9-wire from the amps in the rear driver’s side trunk corner to the factory head unit module. I also ran two pairs of 14/2 to each dash corner. This jacketed cable has protection but is stiff enough that it can rattle against the...

Unlikely the antenna connection is compatible, and even worse - they are awful. They are the worst sound quality of any car audio component. Hard no on FM modulator AUX inputs. Given that the OP wants to use an aftermarket DAC, they are looking for a high quality interface.

Need to know more than a brand and year. Need the model and trim level/options to even start having a conversation. Pac-Audio and Axxess are places to start for adapters that may be available. An external DAC may be pointless if the signal path inside the factory radio goes through an ADC...

The trunk floor is very resonant and in need of a lot of treatment. After full coverage of CLD, the floor is very dead. Then I covered the floor with CCF from my stock of Ensolite that I’ve had for a while. I also treated the bottom of the rear deck with CLD Then I covered it with...

For most of the past year, my expectation is that I was going to install the Hertz HCX690 coaxial speakers in the rear deck of the Camaro. I’ve been excited about these, as they are the best sounding coaxial speakers I’ve heard. However, this car does not lend itself to a rear speaker...
