I have this in my CX-5. Stream from my phone Apt-x HD bluetooth music. Can't believe what an improvement over factory bluetooth codec.

 

You seriously have that in your CX5?

You should get one of these tube preamps and ditch the XM radio. XM sounds like garbage. This preamp runs on 12 VDC.

 

First to be clear my last response you quoted was not directed at you.
Ya see here is the thing. I "tuned" my MAZDA for one specific channel of XM I predominantly listen to using pink noise and my friend who owns a audio stereo shop sound analyzer and playing a variety of music that is played on that one station to adjust all 4 of my amplifiers. There is really not much sound reproduction equipment as in stereo system that can duplicate that.in a vehicle. So YES will sound better then most anything and especially that interesting audio part. you are writing about.
I will say unlike my 82 Camaro where I also measured the total free air space (volume) with 2 people in the car along with pink noise and sound analyzer to build that system , and that was in 1982. That system had 5 amps and 36 speakers.
Back then I use to charge 25 dollars in one of my shops just to design and write up a recommendation for a sound system and speaker locations. And this was when stereo sound contests were just beginning. lol

 

XM RADIO is 128kbps on the high end and 64kbps on the low end. I am running aptX hd at 576kbps. XM is low res, compressed music. It is not even CD quality.
For how much time you put into you stereo, you really should be using high resolution sources that have some good dynamic range.

 

You missed the part that it is humanly undesirable to need to adjust every time you switch to a different kind of music even music source. I prefer XM for availability and the occasional flexibility of a larger selection of specific lessening . Even if I tunned the system for one main chanel.

At some point all your graph on any subject you should gather finding on the internet someday you should test how many actually work (ITRW) with anything you are working on? In the real world (ITRW) things are much different then in a shop or garage with no other sound imputes mudding up the sound reproduction , no matter how well you can tune a system or the device to receive the music. .

 

I am running 256kbps from apple music, then transmitting via bluetooth AptX HD. Not a perfect audio chain, but sounds ok. I can have options to go even higher resolution, but I try to limit data useage.

 

Poor original poster just wanted to know how to mount a typewriter in his car, I mean a CD player.
