Maybe you should grab this:

my cabrio has jehnert door panels, focal rear,jl 1000/1,soundstream 1000watt(for the doors)2-13w6..and when i get into my x5...i like it..its loud, i love the dsp options...i wouldnt change it....and coming from the other stereo i sthink it says lot about the bmw one.

How do you like the Jehnert door panels? I know the guy importing them into the US< but I've never heard them...

I checked out the Eq and it seems pretty impressive, what i wanted to know was for the set UP that I am going with is the EQ going to be used alone or is it to be used in conjuction with the LOC.

Also can you tell me what would be a pluses and minuses in going with a aftermarket 3 way system say a (DLS ur36s). instead of just the 2 way

And if I were to go with the 3 way set would i need say an additional amplifier say a 2 channel amp dedIcated for the rear like a (phoenix gold TI400.2) which would give me a total of 7 channels ( 4 front 2 rears 1 sub).
or is that a flawed way of looking at it.

Thanks

Not quite sure what you mean here. The EQS has 6 channels of throughput and the LC6 has 6 channels of thoughput.

But your OEM amp has F tweets, F mids, F midbass, R mids, R midbass, and sub channels. Your Head Unit has L and R output but no Front or Rear, and it may or may not vary with the volume controls on the radio and steering wheel (I know this last 04/2005 X5 did not support the volume controls on that fixed line out).

How do you plan to interface the LC6? I don't see that it can handle all the channels you need on the output side, and if you use it on the input sidee, I don't know if you can configure the knob on the LC6 to control overally volume instead of just the sub output level that it's labeled to control.

If you use the LC6 on the preamp lines (which it's not designed for) you have 4 channels left over, as you also do with the EQS, unless you "Y" into the EQS and EQ your F and R and Sub channels separately. I find that of dubious value, but I'm not sure what you're planning.

The theoretical benefits of a three-way are that you can get better vocals out of the dome midrange and that its dispersion characteristics in the midrange are better than a piston-cone speaker at the upper end of its frequency response. As speakers go up in frequency, their dispersion gets worse and worse, with an equation that is related to diameter. That's why small dome mids do better than cone midbass for off-axis response.

Of course, I don't see the DLS dome mids fitting in the OEM locations in the dash, so I think it's a moot point. The smallest DLS dome mid is a 2.5" dome not counting the frame, and the BMW cone mids ate only 2" across.

Also the DLS dome mids are not rated to play as low as the OEM cone mids, so they would blow up if you tried to use them as a direct replacement using the OEM signals from the amp.

THe DLS three-ways CAN be run with the passive crossovers that allow two channels of amplification to run all 6 speakers. As with all speakers, the fewer passive crossovers and the more channels of active crossover/amplification you have the better off you can be.

But it doesn't matter much if they don't fit. I'd go low-xover-point tweeter in the mid location and a good capable midbass and call it a day personally.

thanks but I mentioned earlier in my email that i sent you that would I be better off just getting the seven Loc's and cable them like janix did and also does phoenix gold the eq works in conjuction with the LOC.s or by itself.
thanks

OK, in the system we did, we summed the F high, F mid, F midbass, and sub channels.

Then we ran that into the EQ.

The EQ has two outputs. We ran one of those to the fader knob up front, and ran two RCAs back from that to the F and R amps.

The other output of the EQ we ran out to the sub amp.

We ignored the R door mid and midbass outputs because the customer clearly wanted a full-range R door signal, and one of his biggest complaints was how the R doors wouldn't play vocals for squat and sounded tinny.

I beleive that some other X5s do play a "full-band" signal out the R doors, but I can't pretend to know a lot about their changes from year to year and system to system.

Hope that answers your question... sorry about that.

OK, I just logged into my home PC remotely and I see that you sent me an email. My apologies, I haven't read it yet. I'll read it tonight when I get home. My apolgoies for the confusion.

I recently replaced the front and rear midbass speakers and front tweeters in my 2002 x5 4.4 with DSP with Boston Acoustics Pro speakers.

This made a tremendous difference compared to the stock plastic crap 8ohm speakers. I also replaced the factory shitty sub with a Phase Linear Alliante 12"LTD and a (dont laugh, this is really a top quality model) Kenwood KAC 1023 600WRMS amp. I used a caliber high to low converter to convert the signal.

Sound quality is now really acceptable (as long as the echo effects are disabled)!

Only thing I would still like to accomplish is a stereo input for my DVD system, and a dension ICElink for my ipod.

Especially the DVD input is puzzling me, does anyone know how to connect the dvd player in stereo without losing the oem TVtuner functionality??

That's an easy one! $34 AUX input OEM cable. Works perfectly for DVD in stereo. Check the articles or search the forums for 'aux' and you will find lots of info. Does not affect TV sound in any way.
