Try putting the positive probe on the speaker-out negative. (If you haven't tried already)

Did you try this?

Scanned over that, but I got everything to work! Plugged in the negative RCA instead of positive and I got the lights. Head unit doesn't distort also :-)

the negative RCA ?... wtf does that mean ?

Uh, not quite sure, I checked to see if I put the RCA's in the wrong spot on the back of the h/u, but they're all in the correct place, so.

Im asking you dude.

"Plugged in the negative RCA instead of positive and I got the lights"

what does that mean ? you have a positive RCA cable, and a negative one ?

Thats what im asking you by your comment...

Oh. I'm really not the dumbass I seem to be lol. But, to clear it up, the left was the one that gave me signal (black) right (red) did not.

[DD-1 signal/1khz/40hz leds won't illuminate]

so you are running your door speakers off the headunit and the sub off an amp?

if that is true you are just going to have to set your gains at where you think you door speakers distort, or dd-1 the speaker outputs and use that as max volume.

The Crescendos and Tweets in the front are on a RF P400.4, back door speakers are off the h/u. Back speakers don't sound too great at all compared to how good the Crescendos do now.

not downing on you or anything, but If I had of checked an didn't get a signal out of one rca's I would've checked the other one...

Yeah I feel like a dumbass as to why I didn't just swap them to see if it did anything.

Still haven't gotten anything, I don't know what's wrong. Not giving up though.

[DD-1 signal/1khz/40hz leds won't illuminate]

where is your High pass set to on deck and amp ?

On the head unit it's 125, the highs amp is the same. Just sounds best there IMO.

If your HU HPF is set to 125, how the fuck do you expect a 40hz track get detected?

Well it would be easy because it's turned off when I'm using the dd-1.

And this is all being done through the sub amp/sub-out RCA's, not the mids amp

[DD-1 signal/1khz/40hz leds won't illuminate]

are you trying to get a 1k signal out of your sub amp ?

No... Not an idiot haha.

I've tried, I get nothing still. It's bugging the shit out of me lol.

[DD-1 signal/1khz/40hz leds won't illuminate]

if its showing signal, and picking up the 40hz and 1khz track, and your volume is on max, it maybe that your headunit is distortion free at max volume.

Several headunits are.

The volume is only at 45 out of 62... I was setting my gain at 45 because at 48 it "sounds" like its distorting on the 40hz track.

EDIT- and what track are you using to find HU noise ?

Track 1

Dude... your fucking lost....

Read your manual.

If you want to find where your HU makes noise at... you need to play both the 40hz tone and the 1k.

Dude.. read that lil white paper that came with that THINGY you bought... This is not rocket science. ..

I am reading it lol, I've read it over and over again. I do everything it says, don't get any signal light or anything even when maxed out. This is the case only when I'm just trying to see where my head unit distorts.

Did you run BOTH tracks ?

EDIT- if you dont get a SIGNAL.. then something is not right... period.

Only tried the 40hz track because I don't get a signal light so why bother with the 1khz track. What could be wrong then?

Coming right off the deck RCAs ? or are you look from the amp ?

If off the deck, what RCA's did you use ? the sub out ?... are all RCA's open/full ?

This is through the amp. Straight from the RCA's I still get nothing.

RCA's are knukonceptz Krystal. Yes sub out. Open or full?

Stop guessing you bought the tool use the tool properly. Are you running your interior speakers off the headunit

I'm trying and thought I am. I'm running the back off the head unit, front are on a RF-400.4

So did it work?

Sorry man I got caught up with stuff, and I'm at school now. Will have the news around 4 pm (Eastern)

Well, I got a signal 40hz/1kh light to come on so that's a plus. Still can't get it to tell me where my h/u distorts. Hmm.

Yes, speaker positive and speaker negative. Because the rca ground on a tiffany style or differential rca input is not grounded together with the amps ground like on the majority of amplifiers. So grounding to the amps ground, or even a battery ground will not complete the needed circuit to make the dd-1 or cc-1 work.

TBH, dont matter what style inputs the amp has, I just go straight for the speaker outputs to hook up the dd-1 and cc-1.

If your using a 4channel amp, sometimes you might not get signal on the left channel, so you may need to use the right channel, so that is also something to be aware of. Only a handful of amps do this from what I noticed.

But just saying it just in case you run into that issue.

This is all awesome info, crazy thing is though, the manual that came with my dd-1 says the same thing. What a concept.

Haha. You are correct, but my appreciation was really directed towards the info on the Crescendo Amps.

Alright well I greatly appreciate the info. Will go try that now and get back to you.

Going to quote myself from another person with crescendo amps and cant get their tools to work.

Did you try using the negative probe on the negative amplifier speaker output (not the negative amp ground).

iirc the crescendo amplifiers use Tiffany style inputs, which are not grounded and may make it a differential rca input.

There is no physical connection between the negative rca signal on the amp and the actual ground and that may have something to do with the signal not being transferred through the ground when the cc-1 is grounded on the battery itself.

So try it using both the positive cc-1 probe on the positive speaker output of the amp, and the negative cc-1 probe on the negative speaker output of the amp and then you should hopefully get a signal.

I remember someone else having an issue with a 4channel or 2 channel crescendo I thought and they couldn't get signal on the dd-1 with their amp 1 way but the other way worked.

Also some of the older DD-1s with the recessed rca connection in the top, There are some RCA cords that have ends that are too bulky to get the cable to fit into the opening, which wont make a contact and you wont get a signal.

Ive had this happen a few times.

Hmm. Alright. So for both dd1 and cc1, use the positive and negative speaker inputs? Does it matter which one?

[DD-1 signal/1khz/40hz leds won't illuminate]

Are you following the instructions in the manual? Not to be a dick, but it's not like you'd be the first one. As for the filters, you want them open not on, that way those signals don't et filtered out.

Yeah I am, and I get ya lol. Still getting nothing.

[DD-1 signal/1khz/40hz leds won't illuminate]

there is no left channel on a crescendo 1500. and why set your headunit where you can "hear" it distort when you have a dd-1? set it one click under where the dd-1 says distorts

I meant on the right side with the + it's in the left one. And if you read, I can't find out where my head unit distorts because I get NO led illumination.

[DD-1 signal/1khz/40hz leds won't illuminate]

Make sure high and low pass filters are open to allow signals. Test the 40hz on the low/sub-out RCA output from the HU, and the 1000hz on the mid-level RCA output. Turn EQ flat or zero, sub level at zero, use DMM, to check for voltage coming out of the RCA.

So I turn on the high pass filter on the h/u? There's no low pass. I'm a little confused here on the rest of what you said.

[DD-1 signal/1khz/40hz leds won't illuminate]

What amp? Everything flat in the settings? Using left speaker channel?

Crescendo S1500. Yes everything is flat or at 0. And yes, left +
