Check the manual. I *think* that the speaker level inputs have attenuation, and the RCA inputs are capable of accepting balanced and low-power speaker signals on most A/C gear. I would take a short twisted-pair RCA, chop it in half, and use that to run signal into the RCA inputs.

is the EQS even needed with the PDX? it's been a while since i did my initial research but i thought the PDX could take the inputs and you could adjust from there.

I assumed he just wanted an EQ with Programmable Frequency Match

I want an EQ to tweak the sound quality since the OEM HU suck!!! To much midrange!!!!!

Really? . I've tested the HU balanced output, and it was flat as a pancake - except at low levels when it has a slight amount of auto-loudness "happy face".

[manuelpolaco]

I'm not an audiophile but IMO the reason of the high midrange is due to the location of the front doors drives. Don't get me wrong, at normal volume its sound great. But when I am in those days when I want to burn my ears the guitars sounds distorted at high volume.

Got it - but that's not too MUCH midrange, that is distortion. Better speakers and a better amp ought to solve most or all of that problem, right?

You are right, maybe the speakers can't handle high frequencies at those volume. But that is the beauty of the EQ, even better if is a DSP 1/3 octave EQ, you can selective adjust those frequencies that annoy you without compromising others frequencies.

bingo. right on.
that's exactly why I used the audio control EQ.
the factory hu and amp are terrible in this regard.

Only half right. The factory HU output is great - flat as a pancake. The amp has speaker-specific EQ with a huge peak at 1k, it's been tested.

nice - thanks for posting evidence of the crime

is that the non-L7 HU output or the L7 after-amp output?

The HiFi amp output...

here is the sub channel:

I just bought a pair of sws-8xi's on this forum.
Can't wait to get the factory noise makers out of the car.

Jazzed.

Looks more like PN 2-967385-1

They have a cable kit for it, but it runs all the way from the stock deck to the trunk then plugs into the amp. I'm still looking to use the existing harness that is already in the trunk. Seriously; it seems not using the harness already snaked around the car is a bit nuts. Too bad the good people at blaupunkt don't already have a connector for it.

The connector is PN 2-9673B5-1

I bought the sws-8x, they sound great. An excellent companion for the 4" component speakers.

[fdiprete]

I'm installing the sws subs today.
That terrible thump noise from the factory units is providing motivation

Next on my list is tweeters.

The factory tweeters sound like they are subject to high frequency roll off, if in fact the output from the HU is 'flat as a pancacke'. I have the +attenuation on the audiocontrol set fairly high.

I'm thinking about replacing the door and deck tweeters with 1" polks.
Suggestestions that do not require a second mortgage are welcome.

Wait, I said output from the HU to the amp is FAAP... output of the amp looks like the screen shot above.

Diggin you VP. I am using the stock HU but replaced the factory amp with alpines front-ended with an audiocontrol EQ. Therefore the factory speakers must be doo-doo.

SWS install is done. They sound much better. less noise, more music.
That was a lot more work than I thought it would be.
I'm getting too old for this sh*t.

Agree, many working hours to finish the installation. Now I have a lot of back pain.

You will need then a DSP processor that at the same time can accept differential inputs. My recommendation is the AudioControl DQL-8, as it is almost made specifically for the E90. It takes the OEM HU speaker outputs straight, it has signal sensing (no need for a separate remote signal), and you can tune the front components separate from the underseat subs and separate from the rear and a sub. So you can tune specifically for the shortcommings that you found.

Technic,

I saw some other types DSP processor in the forum, for example, AudioControl LC6/EQS/DQXS/DQL-8, JL Audio Cleansweep, Audison bit1 etc. What is difference among these devices? For E90 with HIFI option, which one is best fit ?

Thanks!
