Hopefully one of you guy's have the radio upgrade. My rear speaker puts out hardly any sound. My service advisor turned the bass up all the way. He says it's supposed to be that way. I blasted the stereo and put my hand on the speaker grill and felt hardly any vibration.

What's the deal? The radio sounds like all treble.

I've got the BO upgrade, but it's a sound system upgrade, not a radio upgrade (just to be precise).

I assume you have gone in and checked the settings to make sure the bass is a decent/high level - and that the treble is not too high. I looked at my settings just the other day and it seemed like they had changed (without me changing them). I prefer a middle setting for treble, and a slightly above middle for bass. And the settings I found had the treble too high (which I know was not where I left it).

My system (maybe yours, too) allows to have a left (driver) or right or center focused sound set up. This made a difference for me. I set it to "left" (or driver, or whatever it said, I don't remember exactly) and it definitely improves the sound for the driver's side.

Overall there is enough bass for me. It's not all treble. It's not "shake the world and 4 cars behind me" bass, but I don't want that.

(And I've said this before... the $6,000 upgrade isn't worth $6,000. It's a nice system, but not that nice)

Do me a favor, when you get a chance, with your settings, put your hand on the rear center speaker grill and let me know if there is lots of vibration or hardly any.

TIA,

Radio... Who listens to radio in these cars..!?! Drop the windows or the top and that's all the sound you need....

The BO sound system is my biggest disappointed about the car. Being a bit of an audiophile, I was really expecting a lot for a $6500 up-charge sound system. Not that I've every been that impressed by a factory sound system, but this one is pretty disappointing for the price tag.

Right you are. I have had my 2014 SLS for three years soon and I just now noticed that the rear speaker is barely putting out sound.

Daytona-flyer

What about the rear speaker? Does it put out?

Houdini

I'm pretty sure it does but not loudly. I'll check it next time. But I have a coupe, I think the rear setup is different.

I’m with Newport on this one.....I’d much rather listen to the exhaust note.

When dialing in the sound system be sure to use the CD that came with the car to tune. The sound is completely different.

Daytona-flyer

No CD came with the car. I just spoke with the parts dept. They had no clue as to what I was talking about. Do you get sound from the rear speaker?

I checked, and yes I do get sound out of the rear speakers. It's not super loud, but there's bass for sure. I also checked my sound parameters, bass was at 3/4, surround was on, and it was also set to left bias.

1) The most bass feel in the rear comes from just in front of the indicator lights that warn if you are about to hit something. There is not a speaker grill there, but maybe a "subwoofer" or bass speaker is there (underneath the fabric)

I would say it does not "vibrate". It thumps lightly or medium lightly. It is not a heavy bass at all. But it's there. I'd like it to be a little stronger, but it doesn't have to be.


2) I'm starting to think there might be a software glitch. I checked the levels again, and it seems (not verified) that the treble was set higher again. Nobody drives the car but me and the treble was set higher than I like it. I put it back at "0" (centered) and I'll look again in a day or two to see if it has increased.

As said here, the sound system, the BO which was on my car was by far the most disappointing item on the car. It was down right embarrassing. Any increase in volume rendered the sound to become all distorted.

There was a post somewhere with a comment from the B&O engineers that worked on the SLS stating even they were sorry for how the SLS' system turned out. They amount of space they were given for bass enclosures was inadequate. Also you will notice that if you turn the system on and bass-heavy music is playing you will get a split second of deep, loud base before the audio processing retards the output on the rear speaker. This was intentional to prevent distortion, they believed no bass was preferential to distortion.

I bumped the bass up most of the way and listened to a song with a lot of bass. This was with the top up in my garage. it sounded the way I like it. With the top open, the radio compensates for the changed acoustics. I'll try it out this morning. I found no advantage to bias it left or right but it sounds as good as my stock stereo in my '16 S-Coupe. Well, it came with the car. It was the last iridium silver 2014 in the country. The final edition came out several months after the purchase.

Yesterday, in the garage, I was playing with the radio. Quite a difference with the top up. It sounds great until you put the top down. You loose a lot of bass.

This is from the link posted NewportSLS......

Fine-tuning the sound

The process of adapting the sound experience to match the acoustics of the SLS AMG cabin required around 400 hours of intense testing and retesting by a team of skilled sound engineers. And for the SLS AMG Roadster, when this process was complete it started all over again, as the acoustics needed to be retuned to suit the acoustics of the car when the fabric soft top is down.

Sorry what did you say.... Something about radio...
