I have a blown rear speaker so need to get a new pair back there. I have a 2011 e90 335i.

At present, here is what I have in my car:

Front Speakers are Morel Hybrids

JL 900 Amp

JL w3 10" sub in the trunk

What should I get for the rear passenger replacement speakers?

Is it worth upgrading the subs which are under the front seats?

Thanks,

[Ryan135i]

Plug and play:

Focal
Rockford Fosgate
Gladen
MB Quartz
Alpine

Jehnerts get a three way Jehnert kit keep your morels in the front
and use the door speakers for the rear.
The Jehnert Xe 200 underseats are exquisite.

upgrade your underseats before you upgrade rear speakers

Would you happen to have the exact model of the kit you are referring to? I have looked on Jehnert's website but haven't found exactly what you are referring to.

Thanks,

You can get this from Unexpected Creations from member 6spdcoupe
and or mathematics.
Unexpected Creations reps Jehnerts in the US.
Located in New Jersey.

Looks like you will be short channels unless you loose the rears
I would discuss this with Unexpected Creations.
If you have already bypassed the underseats you have left a big
hole in your frequency range.

I went to a highly regarded local car audio shop today. They recommended I move the Morel's that I have up front to be my new rear speakers, buy the Gladen Audio 201 kit for BMW. For a complete front setup including the floor subs.

Run the rear Morel's off my stock amp and use my JL 900 amp to power the trunk sub and 4 channels for up front and the seat floor subs.

Make sense?

I would be open to any other more value friendly speaker setups compared to the Gladen price.

Thoughts?

If your local shop is doing the install go with them. If you are installing, move the morels in back and then order the Jehnert kit from 6spdcoupe/mathematics and wire the front stage and sub to the jl audio, and rear deck to OEM amp.

What did you start with system wise.
Base system ?
You can't do the speakers you mentioned any justice with
factory power of the head unit .
You only have 4 channels left if you are running the rear sub
off the JL as far as I know.
You need 6 channels to run all the factory locations.
And its is better to run the underseat subs/midrange in stereo .
Morels are regraded as better than most any other of the 4 inch
choices by most why would you move them to the rear.

Thanks again for your perspective. I really like the Morel's and don't see the need to change them out.

What I am thinking is to buy a pair of Jehnert Xe200's for under seat woofers.

I have the Hifi System.

Can I power the front Morel's and the Jehnert Xe200's with the four channels on my JL 900?

Then power the rear speakers through the stock amp. Just need to find a cost effective pair for the rear.

Does this sound right?

Thanks again,

I wouldn't spend money on the rears unless
you are going to amp them .
And as a general suggestion from this board from
some of the people that own shops is rears don't make
much of a difference the overall sound so don't spend
money on them or upgrade them.
Don't know how you wired up a jl 900 and the stock amp in
parallel that is pretty unusual.
I would do the under seats before anything else that will
make a big difference in your mid bass and mid range.

If you are powering the fronts of one pair of channels now
that is kind of compromising the whole front speaker setup.
If you were running the stock speakers off the amp and slammed
it that would explain why you fried the 25 watt speakers in the
hi fi system with 4 or 5 times the power they were rated for.

Well, I went into another very high end car audio shop that is very well regarded and here is what they recommended base on the number of BMW's that they have worked on in the past 15 years.

Given the space limitation with the under seat sub area, it is very difficult for any sub speaker to perform at its best as there is very little space for "air travel". As such, what they recommend for me based on my desire to not spend too much is the Match MS 8B-BMW.2 subs. They are an excellent value. They would be powered by the stock amp and not the JL 900 as the added power would compromise the performance of these subs based on how they like to set up the 3 series.

Adding a mid level set of rear speakers to match the Morel Hybrids that I currently have up front and power these through the JL 900 amp along with the Morel's up front and the sub in the trunk.

They would then calibrate the system and we are all set.

Have not heard of Match before. He does also sells Gladen Audio but as he said at more than twice the price as the Match speakers, I would never notice the sound difference but I would notice the wallet being lighter.

All this leads me to the understanding that there is always more than one way to skin a cat so to speak.

Still debating whether to power the undersea subs with the stock amp or the JL 900. They said that they would be happy to wire both options for me to hear. Will likely take them up on that offer.

Just doing some research on Match now.

I think these people are totaly wrong this reminds me of another thread
where people asked for help when I guy sold them subs and doors
and bypassed the under seats.

http://www.bimmerfest.com/forums/sho...d.php?t=550771

The stock amp is crap by the way.
If I had a choice between speakers and the amp changing the amp
makes the most difference.(although stock speakers are not far behind
on the crap scale)
Can't believe they would tell you to keep the stock amp for anything.

CTuna,

I really appreciate your expertise and input here. This is the real value of forums like this for me and many others. I don't disagree with anything you are saying and just ask questions in an effort to understand this audio maze a little.

So to recap, here is what I think I need to get done and please correct me if I am wrong in any way:

1). Keep my Morel Hybrids up front exactly where they are.

2). Replace the stock underseat woofers with a better quality aftermarket pair of subs such as Match or Jehnerts or Gladen.

3). Replace stock rear speakers with a pair of decent quality 1 way coaxial speakers.

4). Use my existing JL 900 amp to power the front Morel's, the upgraded underseat subs and my sub in the trunk.

5). Buy another amp to power the new rear speakers.

Does this sound about right?

Much appreciated and thanks again!

[ctuna]

That is closer to what I would do.
And the guidelines on this board.

[435MSport6Speed]

Just to be knit picky - the underseats are mids.

My advice would be to forget about 3.) and 5.) for now and see how you like it without rears. If you want to invest in a worthwhile improvement, get a DSP.

Thanks for your input. Highly regarded audiophile on this forum I am seeing. Can I ask you what speakers you would recommend for my underseat replacements and as far as a DSP goes, which brand and model should I look at. I am trying not to break the bank but rather balance budget and value if that makes sense.

Thanks again,
