Changing Audio System on 335is need advice

Hello Guys
I left my 335is 2011 at body shop about a week and a half ago to change the audio system. They put JL Audio High Definition amplifier with subwoofer and focal speakers. The whole system was about 3500$. Yesterday i went to pick it up and i was extremely dissapointed about the quality of sound, it was very poor quality , i thought that the base stereo was actually better. So i left it for one more day now the guy texted me that they reseted the settings to 0 and sound is amazing now. I have to go in 2-3 hours to pick it up. What is your advice ? Is that a fair price for audio system or are they screwing me ? I also have the option to take it out and pay just for speakers. A friend adviced me to cancel the job and go to ABT because they are better. Any advice would help a lot
PS: the body shop is dealer at local bmw

IMO, that price is HUGE. Even the individual system, which sounds great, is $1900 and aftermarket systems from alpine, etc. can be done for under $2500. What else was replaced? speakers? Subs?

What do you mean reseated the settings to 0? If you swap out the sound system does any additional coding need done?

Did they replace all of the stock speakers? Did they replace the head unit? Did you have an equalizer installed? How many channels is the amp? Need more info.

You need to tell us exactly what was done

You need to tell us exactly what was done
Which system you started out with what exactly did they put in and how it was wired.
There is a e9x stereo board here.
(model numbers of all components)
There are hardly any auto stereo shops that can do a BMW correctly.

Not many places can do a E9x right.

Changing Audio System on 335is need advice

This is just my opinion:

1. For $3,500 the system should absolutely pound, especially if you aren't replacing the head unit.
2. If they installed a four channel amp, the bass from the sub will probably be weak or muddled. The subwoofer needs a separate channel or separate amp.
3. I don't know if the stock head unit has an equalizer which allows you to adjust the sound by frequency, but if there isn't and they didn't install one for you, you won't be able to optimize the sound to your specific liking. I won't have a system without one.
4. Did they build a custom box for the subwoofer?

Bottom line is that is a lot of money and they either need to satisfy you or remove it.

I love music in my car and the premium sound package almost satisfies me entirely! I wonder what a $3500.00 audio system sounds like! I think u need to find a head phone jack and put on beats by dre while driving! lol

so the total cost ended up with labor to 3850$. this include: six chanel line lc6i processor,high definition 900/5 5 channel class-d system amplifier, focal speakers ifbmw-s. i can't believe i paid so much for such a garbage system, my old 335i sound was stock and was 10 times better. i would never ever in my whole life make any modification to any car. if it doesn't come from factory as you want, better not upgrade. i changed the settings to the best possible but still when i turn volume up the voice isn't crisp at all. i ended up with the lesson to never rely on any advices from any dealer, they only want to make money - nobody care about quality and customer satisfaction

So this M3 didn't have the enhanced premium sound, even the standard logic 7 sounded good and was tunable. Maybe just a simple speaker upgrade would have done the trick? BSW speakers? nearly $4k seems it could have been better spent elsewhere, I agree.

I don't understand why people even bother to spend money on an audio system. I love the way mine sound stock and wouldn't waste a single penny on an after market sound system. i'm not into audio systems in general and it annoys the hell out of me when people "bump" their system when i'm at a stop light. With $3500 I would take a nice vacation instead.

Don't panic. You didn't necessarily get screwed. Who sold you the system? Service or sales dept? Talk to the person who sold it to you and tell them it doesn't sound right. If they won't help, then go to their manager. Keep going up the chain until someone will listen.

But you need to know what you want it to sound like and get them to fix it until it meets those requirements. If they can't get it to the point of satisfaction ask for some money back.

Stereo systems have improved significantly over the years. I agree that most stock systems nowadays are adequate. However, I also wouldn't be opposed to spending extra money to upgrade the whole system. I spent thousands on systems in various cars over the years. But that was when I drove a lot more. Now I spend a max of 20 minutes commuting and my days of cruising are over.

I know what you mean about the "bumpin" stereos. Even as a teenager I insisted that the sound remain in the car and not rattle the hell out of it. I didn't want people to know what I had lest they follow me and break into my car.

Well Socrate, I am sorry to tell you but I think you are SOL. My guess is that you requested the system. As you mentioned initially, you could have told them that you did not want the new stereo and just paid for the speakers. A $3,500 stereo is an audiophile class system. A car dealer is not the place to go if you want an audiophile stereo. You accepted the system, paid for it, but now you are felling remorse. I do not think a lawyer would do much, it would only cost you more money. My $0.02.

There is nothing wrong with that amp

That's a great amp and focal speakers are pretty good to.
But they wouldn't be my first choice.
My guess is these guys no nothing about how to interface it with the system.
If you really had the base system you need a processor or frequency
flattening device to flatten out the base system eq curve. My bet
is they put everything in the wrong place and didn't balance it out correctly .
Did they replace your under seats how do they have the channels routed.
There have been horror storys like this here before if you do your homework
you can have a system better than L7 for in the 1k to 2k range.

The amp should go in the factory location for the Hi Fi amp where if would be


well ventilated instead of under a cover with no ventilation. The location is in the
rear driver side corner see some of those sticky's I posted.
You have two options with the interface to the amp either you use a processor to
flatten out the eq from the head unit of you reprogram it for Hi Fi output then
a processor isn't needed.
Also do you know the ohm rating for the sub that could be another problem with the heating.
Did they even hook up the underseats of give you something to replace them?

Your problem sounds a lot like what happened to these guys.

some pictures of what they did to the doors would be interesting.

Not if you didn't get an awsome result.

Not if you didn't get an awsome result.
Sounds likey the charged you MSRP for everything.

If you started out with a base system things you have to do is.
Get a device that will flatten out the eq of the Head Unit or recode it to Hi Fi output.
Typical would be a Jl Cleansweep or MS-8 not needed with a recode.
A Technic Harness
Replace the under seats with the Speakers that are known to fit .
Replace the Front Door Speakers with speakers that are known to work add the factory tweeter holders
for the new tweeters.
The HD amp is a competition level amp a XD would have given you more bang for the buck .
If you are a bass head and want a big sub that will run you and extra 1k or more but its not necessary
if you do the under seats right and your not the kind of guy that just has a sub for image purposes.
Why did they use that audiocontol level shifter its not a processor I think.

i trusted them because they are bmw dealer. i didn't want to let my car in the hands to anyone.
On topic: the amp gets very hot, you can't put the hand on it. Also it sounds good for like 5-10 minutes, then the quality becomes very poor. If i stop the car for 30 min, it will sound good again for about 5-10 minutes until the amp gets very hot. I'm thinking to take it to ABT store but already spend 3750$ on this, so i think i'll have to take it back to dealer on monday and ask the manager to replace it or remove it

Why would you trust BMW with audio

Why would you trust BMW with audio.

Since they put the crappy one in the car in the first place.

There audio designs have been getting weaker with time.
You need to understand something about audio before you can
modify these things successfully .
