Yaris Sedan Deadening and Sound system upgrade

That's tough question. I know exactly what you're talking about though.

What I need you to do is to find a phasing track and run it through all of your speakers independently. Make sure your phasing is on before we blame anything else.

Maybe I know but describe to me a phasing track?

A track where you have a voice that is presented in phase and then out of phase.

Don't worry, I'll send you a couple.

Thank you,

I have the one from IASCA, but what do I do? play it with Tweeters only, Mids only, Lows only?

or what's the process?

D do you have your headlights on in the morning ? And not when you come home ? Maybe heater or ac. Could be experiencing volatage drop. And it's effecting your amp.

I used to think my audio sounded louder at nite than during the day.

Lights are on, heating is on or AC all the time but I see the volt-meter at:

14.1 v in iddle

13.9 v cruising

It's not about sound level, it's just the Center Image that moves 2 or 3 inches left or right.

Thanks

Where's your voltmeter connected ?

If you say battery that still isn't what the amps seeing...since you have 3 amps.

You have a 4 channel amp correct ? 2 channels per each side correct ? I'm going to ask a question, if you messed with the gains on one of the L or R channels of that amp...would it move the image ?

P-99 Head Unit comes with a voltmeter. The connection... I don't know.

Yes I have 3 amps.

Gains? it's one gain per channel, right and left together.

The IASCA one is okay but the vocal range of the female isn't the best. You needs make voice track. There's one on a USACi disc.

What you do is play that track through each pair of speakers, muting the rest. It'll take a little while. But switching phase if the speaker sounds out of phase should bring the imaging snap center and raise the stage a little. It's almost a night and day difference.

...the catch? You need to have your speakers level matched off an RTA.i wish I had a day to spend with your car...

I've done that before but without muting all the other speakers and leaving a single pair, I will try that tomorrow.

Now speakers level matched...? is this when you run pink noise and with the EQ try to lower the peaks and level the valleys? while looking at the RTA with the Mic on pilots side (sweet spot)?

I went through this many times, I believe I can recognize when is out of phase and how to correct it, Cool.

Now I'm going to do the RTA level match for the speakers.

[sqcomp]

On the RTA...

You'll want a pink noise track.

Place the microphone at ear level.

Mute all speakers except one (tweeter for instance).

Get the level on the speaker to read fairly flat across it's listenable major bandwidth on the 1/3 octave.

Write down the levels on each band.

Mute that speaker, then switch to the other side tweeter and repeat.

Match the speaker levels for the pair using the measurements from the first tweeter.

Once those two match, mute them both and move on to the next speakers, repeat the process for all speakers.

[sqcomp]

And yes, different gains can change the sound...

Honestly, there are many variables that can alter the image and stage.

I've also found that the P-99 voltmeter under rates your voltage slightly off battery measurement. There are also explanations for this...

[derickveliz2]

AAAAAAAAAAAAAAAAAHHHHH!

Almost 3 am...

I just finished filing my Taxes, what a relieve! now I can prepare for the 21st!

Thought so, Loll i guess i trouble shoot from the hardware side of things vs the processing side of it.

Reason I asked about voltage is i thought D had recently rewired a speaker, due to a loose connection ?

I'll let you guys trouble shoot and maybe it's all in the processing. I deff wouldn't rule out an RCA cable, or even a channel on the amp. What is being perceived as the center image moving could be the early signs of something giving out.

Sq how did you know something had went out at finals ? Was there any warning at all ?

[sqcomp]

^are you asking how did I know something went wrong at finals with my processor?

If that is the question, the answer is because the week before finals I had heard crackling in the right side. The night before the crackling increased and then the entire system went to full volume for a second then...dead silence.

In a matter of hours I had to NASCAR the hell out of the system. My cousin and I were throwing panels left and right, taking seats out, removing carpet...

It happened on finals day as well. Noise noise noise! GRRRRR! Noise in the source. We tried everything we knew to eliminate signal path noise. From chassis grounding the source and amps to the "magic" wire on the RCAs.

It ended up that somehow feedback from the processor "explosion" fed back to the deck and partially killed that as well.

Rule #1...don't have some yahoo mod your $hit!

That is one of my many issues that I have with Team Hybrids. Apparently they never felt the need to let me know that Jeremy Carlson's failure rate on his mods was nearly 100%. I found that out after finals...oh boy! I went to the moon! I still get heated just thinking about it. It's called integrity and being forthcoming about results. Boy, did that not happen.

[_S7V7N_]

Lollll. Sounds like he just soldered some sh!t together and said "here. Try this "

I'd deff check the voltage at the amp for the mids and highs in the morning. Then again on the way home. We usually asks how summer and heat effects our audio equipment. But how does extreme cold.

[sqcomp]

Yeah...something like that. I now have a paperweight that Pyramid Audio can't fix because Audison won't release the schematics. I could go through a back door deal to get the schematics but it just isn't worth my time and effort.

I'll prolly sell it on eBay as a replacement parts piece for $100 shipped.

There's no way I'm having the guy who originally modded the piece EVER touch anything of mine again. Heck, I've napalmed the HAT/Team Hybrids bridge so hard that my name is on their untouchables list.

...funny thing is, I'm happier being on that list. At least I won't get screwed by my own "team".
