That sway bar seems to take the rear end movement down and place it on the front wheels much more significantly. The rear end wiggle is much more controlled, dare I say almost non existant. I'm waiting for a dry day to see what these tires can actually do...

Isn't that awesome!
The best mod for suspension, I remember when I tested mine after installing, besides a big smile on my face I said... "Feels like a Go-Cart"

Improved the stability at high way speeds 100% I'm talking my cruising commute that ranges between 70-90 MPH

Ok today I found an awesome way to adjust my center image:

I had my cellphone right in front of the instrument panel (arrow 1) with the GPS rolling and telling me what was my next turn. When... I just realized that...

While listening to a track with a very solid center image I noticed the voice of the singer was behind my cellphone's voice, a little bit to the left, so...

I moved my phone above the instrument panel (arrow 2) now playing a song... Still my center image was behind so...

I moved my phone behind the instrument cluster (arrow 3) in the center of the dashboard where the windshield meets... (Note that this position is about 5 feet from my right ear)

My center image was some how next to the phone's (playing another song in speaker voice) so...

I proceed to adjust my Time Alignment (T/A) to mach the position of my cellphone playing a different song, since it's mono gives me the feedback of a center channel where I can match my center image.

End result while experimenting with this was really good and makes sense to me, what do you think?

Conclusion: a new way of Tuning may be accomplish using my cellphone with one speaker and placing the speaker on arrow 3 (see image below) adjusting Left and Right EQ and T/A to match my center image. I got to try this over my lunch time this week.

Phasing! It's all about phasing.

I know about phasing in my own way of thinking, from...

Subwoofer > Lows < Mids > Tweeters

But I'm confused on if it's a left to right phasing?

Could you expand and explain a little bit more about phasing, please

D.

[sqcomp]

Think phasing for imaging detail and amplitude for imaging placement.

With the P-99, don't be afraid to play with the amplitude of the left and right on the four way crossovers.

Oh! It looks like I've sold one of my big amps. I'll be replacing it with a full range D class piece 1/4 of the weight.

This is what I did today...

By putting my cell-phone on speaker (on arrow 3) Playing Pink Noise
I get a physical sense of where the center image would be.

Then I go through the process of playing each frequency induvidually and
adjusting my EQ, Left & Right to match the location of the Pink Noise played by my cell-phone.

I did it once this afternoon and works really good, after comparing my previous set up (Left & Right EQ by ear)
improved the center image and I believe I can go further out one more time
by projecting the physical location of my Pink Noise source to the left,
therefore placing the center image even further outside the windshield.

We'll see.

Well after trying and trying didn't work and I found out why!

My right tweeter is not working at all!

Trouble shout all the way down from the RCA to the amp and the signal at the wires, every thing was fine, my right tweeter is not working!

So after contacting Hybrid Audio Technologies for help the Founder (Scott E. Buwalda) replies back withing 7 minutes...

That's is what I call "Costumer Support"

Try that with Pioneer and/or Hertz! I've done it before and takes about 2 weeks to get a reply.

This is why I like the product. The support is great.

Update, I sold both of my big amps and am readying to sell my 4 channel. The next experiment in sound will be to hear a vertically bi amped system.

What I've done is to purchase two 5 channel amplifiers. I'll be bridging the first four channels to get a more powerful two channels. Then using the three channels to work the left side speakers. And then logically the same thing will be done to the right side speakers. I'll have a mono subwoofer amplifier on the sub... I'm taking one ID eight out of the car and simply using a single 8 inch subwoofer set up. That's all about space for me.

I'm sure I'm going to see my gas mileage go up after having remove these giant amps. It took me all of about five minutes to take them both out.

Hey Derick,

Thoughts on this idea...

You know my bit one? I need to have it fixed. I'm thinking that instead of selling it to use it to make my home system completely active.

What would Derick do?

I'm very new to Hi-Fi home systems, I would say sell the bit-one and get a big right & left EQ

I don't see my P99 at home it would be overwhelming don't you think?

Sounds like a metamorphosis of an Infinity 4 door sedan G35 and a Yaris! LOL

I would like to try an old 10" Solo-Baric under the glove compartment! I think it uses about the same volume of (2) i6SWs

Scott's G was nicely finished. He spent a LOT of time on the tune. It's nothing that can't be topped sound wise by another well tuned vehicle.

What I've learned over the past several years being very close to these high-end competition systems is that the interpretation of good sound is so widely varied... Secret is to get all speakers phase correct and then tonally correct. The first is the most important. Everything else will fall and place given some time with the tune.

There have only been two vehicle systems that have truly make me wholeheartedly enjoy the experience of the music...and Scott's G and even Black Betty aren't in that number (still sounding spectacular mind you).

I say give the Solo 10 a try!

[derickveliz2]

Is it possible that Sub and Lows would end up on the same phase? or my ears are tricking me that sounds better, is there a way to check phase mechanically or with a method? you know I'm doing it through the P99 menu and not switching the wires at the terminals of each speaker.

To me phasing on the low end it's more obviously than with the Mids and tweeters.

Any suggestions? I really need to dig in more about phasing.

SQ, I think a good set up of separates at home or even a good all in one receiver would negate the need for the Bit One at home. You preamp section is much more sophisticated on a full size good quality receiver. I'm partial to Denon or Yamaha receivers, but that's just me. I have Denon upstairs and down, here at home both with Klipsch Reference loud speakers.
