Gents, looking to add a little bass to my new 21 GMC Sierra. This is a non Bose system and works fairly good to be honest. Just need some of the lows to come through. Has anyone any experience with a powered sub unit that fit nicely under seat, behind rears anything like that?

New to this forum, so please excuse my ignorance if this has already been answered. I looked to see if there were answers elsewhere, but haven't found them to all of my questions. I recently purchased a 2015 Suburban LTZ and would like to add CarPlay primarily. My questions are:
1. My truck was built 3/24/15. I have seen conflicting reports that I can just replace the HMI module (upgrade from 2.0 to 2.5) vs also having to replace the box under the center console. There was some discussion that later build dates can get away with not replacing the other module. My truck does have the Text option on the MyLink screen if that helps any. Are there particular part numbers I need to retain use of the Rear seat entertainment system or do all the boxes work with it too?
2. Since new modules require programming is this something the dealer can do without a lot of hassle (i.e. I am adding a non-original part number to my truck. are they going to give me crap about it)? Also, are there aftermarket tools that I can use to do this? I don't have anything like that, but if I have to go pay the dealer $150 for them to program my box, I would consider just buying a scan tool system for future use
3. As I mentioned, my truck has the rear seat entertainment system. Are there options for adding HDMI or other inputs for this system? Not sure my family will ever use it in its current config (we do almost all streaming these days). i have seen screen mirroring solutions, but my understanding is they only allow mirroring on the dash screen and not the RSE screens. Any options there?
Any help is greatly appreciated.
I have a 2003 Yukon XL 2500. The radio started to cut in and out, and then soon gets to the point where there is no audio at all. No chimes and no radio. However the rear radio headphones still work. Thus I thought this was the bose amp and changed the amp. The new amp made no difference until I pulled both fuses and checked everything. I put the fuses back in and I had sound. Great. 2 hours later on the new amp the radio started to cut out again and then I had no sound. No chimes, no radio.
I can restore the radio sound by pulling the radio fuse for 5 minutes, plugging it back in and all audio is restored. This does not last long and soon I will be back to no audio at all. It is not the amp as a brand new amp does the exact same thing. So how do I figure out what is wrong? I don't want to start replacing things as that did not go well with the amp. I have read that maybe there is a bad speaker, but since the speakers plug into the amp a bad speaker should only impact the amp. Also since the audio starts to cut in and out many times (longer each time) until there is no audio at all I can't imagine a bad speaker causing that. Once the speaker is detected it should cut the audio off until reset.
Only pulling the radio fuse, waiting and then putting it back, will restore the audio. Is the radio bad? I pulled the codes and there seems to be nothing for the radio once the audio is lost.
Thanks for any help!
