Anyone from the Raleigh/ Durham area in NC get those rear speakers working better?

Just moved to the downtown Raleigh area and am looking for anyone in the area that got work done to make those rear speakers sound better. is there a master tech at the best buy around town or other good audio shop? I was able to get the fade option but doesn't seem to help much...

Have you tried the tips in this thread? https://mbworld.org/forums/sl-class-...er-volume.html

I have a 2017 SL so I had to pay to get my speakers working by installing an Alpine amp, but I followed the advice in this thread to get my mom's 2016 SL rear speakers working and it made a huge difference and saved her a ton of money that I had dropped on my car. If I am reading your info right and you have a 2015, I would try this advice first...

Thanks for the tip. I actually did follow that link a while ago, entered engineering mode, and got the fader working. It didn't engage the back speakers enough for me so i'm looking to get that alpine amp installed. I was just looking to see if there was anyone in my local area that got that done at a local shop that they can recommend...
