With the MS-8, I felt like the center channel really improved the sound stage.

You really don't trust the experiences of the more seasoned installers do you?
I see you still can't let go of that center channel pipe dream.

All the reasons you were given before, and now the above replies, all still apply. Sadly, your best bet is to get an installer to help tune that system, or have someone like Nelson share that tune.

Honest, no BS, people aren't trying to steer you wrong. Not to sound like a jerk, (sorry, I come across that way) but if you aren't getting a good soundstage with the 82dsp, then you're simply doing it wrong.

Dude relax. I have already let it go. The reason I asked about it agian is because the tune in my 82DSP has center channel in it as it is a F30 tune. More than that, I already had my center channel speaker mounted there from my MS-8 days. Anyways, this forum is for asking questions and getting help from more experienced people. And I got my answer and I did infact rip out my center speaker. Now you can let it go too.

Unfortunately the E90 that i was supposed to tune i had A/C problems. I have a E92 M3 book for next week, hopefully he shows up. He already cancel 2 appointments.

i will be very interested in the e90 tune and how it compares to where I ended up with my helix dsp tune in my e90. not so much in the eq settings because I am running morels and kickers under the seats, but in how the time alignment settings look for the door and underseats.

[e90bmw328i]

Finally finished installing the MBQuart Mids and the Seas H1396 Tweeters in my car's front doors. Boy! the clarity is so good. The tweeters reproduce tunes so clearly. It may be due to the additional crossovers that come with the MBQuart. The stock speakers and tweeters are just not meant for a car like this.

I am still running the stocks subs and stock rears. I think I will stop spending money here as this is just right for me. The e90 tune may sound better. I will wait for Nelson's tune but with the F30+BSW tune, the imaging is excellent.

Working on the E90 tune My friend came through!

[e90bmw328i]

Awesome. Please share the tune when you have it.

Any updates regarding the Tune, Nelson?

Also, I am planning to switch out the rear speakers with this one:

Match MS4X
or
Kicker-41KSC44

What do you think? Are these good options? The Kickers can handle lot more power than the Match speakers.

Yes its ready, i'll email it to you shortly.

Don't bother upgrading the rears. Save your money. Get the Jehnerts 8" midbasses and call it a day....

If you have extra money left over than you can upgrade the rears.

Thanks Nelson.

With the Dynavin N6's Dynabass set to little less than Midway, I am pretty happy with the bass. Its certainly more pronounced that I expected with the stock subs.

Hi Nelson,
I tried the e90 tune today. Now I am kinda confused which I like more .

• The front doors are lot more pronounced in the e90 tune.
• For some soft songs, I still like the BSW tune you sent for the F30 as that gives me the feeling that the stage is in front me.
• The F30 tune was a little on the soft side (mid bass is less compared to e90)

Now you are forcing me to buy the remote for PP82DSP so that I can switch between the 2 profiles on the fly .

This is certainly "the best" audio investment for me. Thanks a lot!

Great breakdown. You're right, the E90 tunes is what i call a "POP" tune. it's like a top 40 friendly tune. I changed it up a little because i know most of you guys have upgraded speakers. The F30 is a pure SQ tune and i will probably make some changes it the future.

The remote is a MUST. I couldn't live with just 1 preset.

[admranger]

Intrigued by the SQ tune.

I have the simple JL XD600/6 amp (technic harness) for my 2011 E90M3 w/HiFi sound. If I understand things correctly, this amp is essentially plug/play and will make things sound *better*, right (after the SQ tune, that is).

In my E46M3, I have Hybrid Audio Technologies Clarus and Legatia speakers, but I really don't want to do as much custom work as I had to for that...

So if you can make the HiFi system sound and image as well as my ATC SCM 19v2's can in the home system, I'll squander, errrr, spend some money on car audio again! Coming to CES or SEMA?

Correct, funny I created the tune with an 11 E90 M3. He bought the amp after listening to the car for 2 minutes.

Nelson, do you sell the remote for the 82DSP? I am seeing that only crutchfield sells it in the US.

And where did you mount the remote in the cabin? I am planning to just leave it below the driver seat with some velcro. That should be fine right? Thanks.

Yes I do, $60. Yeah that's fine. That's how we had on the S6.

[dbworld4k]

I want this soooo bad. Ugh.

[e90bmw328i]

Now I am considering adding a trunk sub for under $300-$350. I have been reading about corner mount subs (similar to musicarnw's enclosure), regular sub box or the storage area in the trunk (similar to BSW's ghost system).

Many thanks to this thread:
Kaigoss69's Sub analysis

I dont have a ski hole in the rear seat. So IB is not an option.

This points I considered was

• dont want to cause rattles in the trunk and have them come lose
• dont require too much power
• Just enough to fill the lower notes
• dont lose too much trunk space
• Dont want to be driving down the road with loud bass and people looking at me like I am an idiot

Given my constraints, I came up with this setup:
Pioneer TSWX2502 setup in downfiring setup along with ARC Audio 125.2 bridged.

Is this a good setup nelson?

[Wongway]

If you keep reading through the various subwoofer discussions, you'll find that in the E90's (especially more so for those without the fold down seats and/or ski pass) the trunk ends up being a bass trap.

One of the reasons the ski pass setup works so well is because the subwoofer is literally firing into the cabin. There's much less wasted energy for the waves to try to penetrate through the trunk and into the cabin to be heard/felt. The obvious downside to it, is that you will take up an oddball sized section of your existing trunk space.

While the idea for your sub doesn't necessarily mean it will be bad, it will likely take more power to overcome the sub getting basically "trapped" inside the trunk.

Putting the subwoofer in a corner enclosure such as Musicar's takes advantage of what they call "corner loading" to effectively use the barrier as a "boost" so to speak.

Most of what I just said above is a very broad over generalization. There's real math and physics behind it all that's probably a bit beyond me being able to break down into easy explanations.

TLDR;
Ski Pass = highest quality
Corner loaded enclosure probably your next best bet
under trunk floor enclosure will likely give you the lowest output.
All of the above is assuming the same amount of power ratio.

Basically, to give the same effect that a Ski Pass enclosure can give you, you'd have to have much higher amplifier output, which also increases the chances for things to rattle to hell back there. Again, broad over generalization, but should give you the idea.

Darn it BMW for soundproofing our trunks to this extent. Thats pretty much what kaigoss' thread summarizes too. So your generalization isnt off.
If I can find a back seat rest with ski hole, I should switch mine out .
