I went through the measurement process and entered the measurements into the head unit. I set crossover points for the speakers and from there I adjusted levels to help center the image more. I was happy with how everything sounded but the imaging wasn't great. It was, for the most part, centered, but there was smearing. I attributed it to the fact that my front separates were on passive crossovers, the mid was in the door, and the tweeter was up high in the pillar. With such separation I had been searching for a compromise in measurements that would give me the best result.
No matter what I did, I still has smearing.
Out of curiosity - and since the SPH-DA120 has the Auto EQ feature - I decided to order the mic and see what it could do.
When it arrived I plugged it in, started the procedure, and shut the door.
When the Auto EQ process was done I was curious to see what kind of results I would see. The distances for each speaker were more than 10 inches from my real world measurements which I found interesting. The subwoofer was measured to be 119 inches away which would put it outside of the physical space of the vehicle. To be honest I think EVERY measurement that was in the head unit after Auto EQ would place the drivers outside the cabin of the vehicle. Odd.
When I looked at the levels the Auto EQ had given each speaker I noticed it had the driver's side (closest) at 0 and every other speaker (except the subwoofer) at -3. The subwoofer was at -15. I thought it was odd that the Auto EQ left the closest speakers at 0 and cut everything else. I believe I had the front at -2 on the driver's side and +2 on the passenger's side to get the best center prior to Auto EQ process. I had the subwoofer at -5 and the factory rear speakers I had turned off in the head unit.
Anyway, with Auto EQ complete, I played a few tracks with everything set to Auto EQ settings. First was track 25 from the Sheffield/A2TB test disc. This track is a stereo recording of three people describing their positions in the sound stage. The first person is a guy saying he should be on the far left of the sound stage, second is a woman saying she should be in the middle of the sound stage with no part of her voice coming from the left or right. Last is a guy speaking from the far right of the sound stage. With my physical measurements I could hear that the woman was centered, but a portion of the woman's voice also came from left/right. I figured this was due to the different distances between mid and tweet on each side. After the Auto EQ process she was locked in on center.
Next was Don't Know Why by Norah Jones. She was also locked on center and the song sounded better than before but seemed to be lacking a bit in bass.
The Eagles Hotel California from Hell Freezes Over was next. This song sounded great but the bass drum was weak. I finally adjusted the subwoofer level from -15 to -7. At -7 the drum came to life and sounded like it was up front. Any higher and the bass dragged to the back a bit - to the physical location of the subwoofer.
As far as the EQ settings, I haven't touched them. They're perfect. The Auto EQ software has to have more EQ bands available than what we get on the head unit's interface.
Now, crossover points. The SPH-DA120 allows users to set crossover points for subwoofer, front, and rear speakers. I had the 13TW5 on the SR1D crossed over at 63Hz @ 18dB/octave. The Auto EQ process changed that to 125Hz @ 18dB/octave. I changed that back to my original 63Hz setting. The front and rear speakers where at the same crossover points I has used prior to Auto EQ so those didn't change.
Overall, I'm happy with the results. The one spot where I think the Auto EQ process could use some work is determining subwoofer crossover points and level adjustment. My 13TW5 on 460W from the SR1D shouldn't be pounding out mid bass at 125Hz. That may be fine with the subwoofer level set to -15 like the Auto EQ had done, but when actually listening to music with Auto EQ settings on the sub, the overall bass output was weak compared to the rest of the system settings.

Finally, high school graduation loomed and it was also time to graduate to a component stereo system with speakers. For me, it was Pioneer. Actually, I think it was Pioneer for everyone. I can't even remember another brand out at the time. I know I went through at least two sets of receivers, turntables, tape decks and speakers. Then, right before I received my first iPod, I started switching to Onkyo. I can't remember why. It didn't matter, though; after that first iPod, it was goodbye to large stereo equipment. Packed out of the way, the stereo stand then held printers, scanners and other computer components.
This month, the stereo stand now holds a turntable and this Pioneer Elite Amplifier. Soon, I'll put an old Onkyo CD player on it, too, as soon as I find it in the closet. Nearby, are two very old Pioneer bookshelf speakers. It's a start. So, how is this Pioneer integrated amplifier different from an old Pioneer receiver? Well, to begin with, it has no radio receiver, which is fine, since there are really no good over-the-air radio stations any longer in my area. You also can attach to it components that never even existed in the old days, such as a network audio player like the Pioneer Elite N-30 Audiophile Network Audio Player with AirPlay & DLNA 1.5, and an iPod or iPod dock. (To attach the iPod, you need AmazonBasics Composite AV Cable for Apple iPhone 4/iPad 3rd Gen/iPod - 6.5-Feet (2 Meters). It further has jacks for a SACD/CD player, a turntable, a tuner, and a CD recorder or tape deck. (You can record from any of the other audio sources connected.) Two sets of speakers can be attached either by cables or banana plugs.
Sound wise, it is a whole different world from the smaller Bluetooth speakers. But I'm no sound expert, and my speakers are on the small size. It also has a remote control that can do everything. You'll need the larger headphone adapter, too, if you only have headphones with the small plug that fits into an iPod, such as the Premium High Quality Adapter STEREO GOLD Plug 3.5mm M to 1/4" F Adapter Metal - 3.5mm Stereo Plug to 6.35mm (1/4 Inch) Stereo Jack Adaptor - Gold Plated - Lifetime Warranty. This Elite component is truly beautiful, much nicer looking than any other Pioneer component I ever had. But back then, all stereo components looked beautiful, because it was the most beautiful way to listen to music. I love the practicality and small size of the iPod, and the small wireless speakers you can use with it, but it's really not the same as using large stereo equipment, large headphones and large speakers.

There are a couple "tweeks" that I would suggest; first, get out of the car. Once the countdown starts, get out close the door. I found that the results were much better without my presence mucking up the sonic landscape. Also, the placement of the Mic is paramount and should not be taken lightly. Follow the directions!
Oh and the system turns off the hpf on the front speakers, I turned it back on and left the setting where the computer placed it. In fact, the only thing I changed was,I moved the subs lpf a bit up to cover a small gap I felt was in the mid bass range... of course, that was caused by my turning the front speaker hpf back on so.... At the end of the day, I believe this to be an awesome product, especially for those that aren't well versed in the setting of an eleven band eq.

I own a Bose Lifestyle System III home theater system with Adapt-IQ so I have been spoiled with a system that does a good job with it's own hardware. The Bose calibration process does a series of frequency sweeps that sound like very loud laser sound effects, followed by subwoofer tones that sound equally impressive. The end result is nothing short of amazing.
Granted, the Pioneer has to work with whatever speakers and amplifiers are in any given vehicle, but all it puts out is loud white noise that sound like the static between radio stations.
The Pioneer calibration sequence goes something like this:
It tests the rear speakers with a given level of white noise
It tests the front speakers with a given level of white noise
It tries to test the subwoofer but I have none
It checks left and right rear
It check left and right front
It checks all speakers
It repeats this process a few times - all with white noise at varying volume levels but seemingly in the same frequency range.
I was expecting some kind of frequency sweep, highs, mid, lows, but nada - just white noise. So it is no wonder that the EQ settings are all over the map.
I can do a better job adjusting the EQ manually.
It may work best with a system that does not use an external amp and one with a subwoofer attached, as long as you like finely calibrated white noise. I don't know how Pioneer could expect to correctly set low frequency and high frequency bands without letting the calibration speaker hear them.
I would save the money.

I also know for a fact that the AutoEQ function WILL run. Just as an experiment, I ran it with a 3.5 cable plugged into my iPhone running a microphone app. The results were laughably bad, but I wasn't expecting much. I just wanted to verify that the AutoEQ function worked.
Given that, and after 8 months of deliberation, I was excited to finally get the actual, proper EQ mic.
It feels really cheaply made, to the point where you wonder why they didn't just give it to you with the head unit.
Found a quiet spot, set the car to ACC, plugged it into my spliced AUX input, turned off the head unit, and ran the AutoEQ. It ran through the first round of pink noise bursts, then stopped.
"ERROR: Please Check Front Speaker." The manual tells me this likely means that there isn't a good connection between the mic and the radio.
So I figured it might be my splice job, so I pulled the radio out of the dash, and plugged the mic directly into the back of the head unit. Tried it again. Same error. No dice.
So either I am doing something wrong (Not sure what that would be...) or this unit was defective. I'm going to assume the latter, and am returning this unit for a replacement.
If the new unit works as intended, and gives me good results, I'll bump up the rating.
If not, then either Pioneer's QC is REALLY terrible, or I'll have to start reconsidering my ability to plug one thing into another thing...

There are many much cheaper stereo amplifiers, and if you need to take just a few audio sources those will probably be sufficient. But for the niche who want to
1. Take many RCA inputs (lacking digital inputs and outputs USB, HDMI, optical)
2. have two different sets of stereo speakers (A & B outputs, for A, B, and A+B output, each with 50 W)
3. Willing to pay extra for premium look
4. Doesn't need digital in or out
5. Doesn't need a subwoofer out
this might be right for you.



I purchased the Goliton brand cable on Amazon due to the price and good reviews.
This piece of crap lasted maybe 4 weeks before the sound from my IPhone 6 quit working through the cable.
I will be looking for a different manufacturer/cable for a replacement.


LISTEN UP! If you like your horrible Dr. Dre "beats" headphones, you will HATE what this will do. It CORRECTS your audio, not scooping out the mids and peaking the lows and highs like those god-awful pos's.
If listening to "corrected" audio doesn't make any sense to you... This might not be a good fit for you honestly.
I auto-eq'ed my pioneer and set the listening position to all seats... All of my ear fatigue went away and my system now sounds great with a flat eq. Sounds like what I'm producing. :D
LOVE THIS GUY!
Again, If you are a audio producer/audiophile/want to listen to the way the music was MADE = YES!
Dig stupid 'beats' headphones or bose systems = STAY AWAY!

I attached the GEX-P20HD to my 2011 AVH-P2300DVD head-unit - What a disappointment!... I lost a lot of features on displays of radio station information - a lot of features were lost when I added this upgrade!
The sound - yes... there was an improvement when listening to HD programing!.. What a difference!
so... at a glace; I can tell you - that you need to do your homework - in order to justify your return on investment!
If you are happy with your head unit and the displayed information - and you want to impress your friends with your always looking cool Pioneer System.. then I will recommend.. to save your hard worked money!
This unit will not add any more features to your head unit - in order to get a good ROI - you you need to live in an area where HD programing is abundant and plenty!
Installation is easy and pain free! - In less than 20 minutes you should have your unit up and running!

I did not personally install this unit since I have an audio shop near me that does all my installations. It only took them a few minutes and off I was enjoying the sounds of what appeared to be a new radio in the vehicle.
I can highly recommend this for anyone who has the radio already in their car and is able to except this add-on.
