Reviving this dead topic. Read on!
Not just cars, but carsound. OK, I generally do something to upgrade the sound in my cars. The bug hasn’t exactly hit again, but it’s biting just a little.
I have a 2024 Cadillac LYRIQ Luxury 3 with the AKG 19 speaker sound system
See this thread for some specific problems
The above link shows current discussion about the subwoofer that does not care for Chameleon - Trentemøller
I took the car to a local car audio guy. Thoughtful. Did a search for something like the FOCAL subs that are direct replacement for OEM. Everything in this car is integrated electronic. I am able to improve the sound buy using ROON ARC via CarPlay. I’ve set a 6 db bass shelf at 50 hz, dropped mid-bass by 2 db or so at 200 hz with a Q of 0.5 and put in a +3 DB at 400 hz with a Q of 2.5
That seems to give a tad more deep bass, thin an over-warm mid bass and address a slightly odd drop out. I’ve reduced the surround effect and moved location to front. With all the speakers, though, the only “sub” is that 6x9 hidden behind the rear passenger seat. Photos in the link above at the Cadillac forums.
The ROON ARC is not the most satisfactory solution - it only works with my ROON server, personal library and QOBUZ. It’s not system wide. The GM/Cadillac infotainment system is based on ANDROID AUTOMOTIVE (not Android Auto) and there is no system wide EQ, There are Bass, Treble, Mid tone controls and fade/surround crap. No APP, and one doesn’t root something that controls much of the vehicle’s software.
I would prefer a hidden solution, not really wanting to have some box sitting forever in the cargo area. I’ve thought about grabbing the SVS Micro 3000 from my office and plugging it in. I have a fairly robust 120 V outlet in the car - I doubt that the class D amp in the Micro 3000 would blow it under normal use. But then how do I get signal to it? I’ve been running it wirelss, but there is no option to add a sub to the system in normal software.
I guess I could tap the signal going to the sub in the floor under the seat. But that is a lot of work just to try something for yuks.
Might go back to the audio guy, and see if maybe they could 3D print a surround that could put something slightly larger in the space. I think an 8 inch might just fit with a custom surround…
Thoughts? I can’t find a 6x9 SUB only. Don’t want or need coax or 3 way. Don’t need a mid-bass speaker at all.
