I agree with Steve, if you have more than one amplifier in your system the CC-1 is a must. On the surface it seems like if your crossovers weren't adjusted properly it wouldn't make that much of a difference in output, only in sound quality. FALSE. Example: A DVC or 2 subwoofers on two amplifiers. Amplifiers are legit 3000 Watts per channel. Crossovers on these amps were set "by eyeball" Amplifiers have 24dB/Oct crossovers, actual crossover point set at 65Hz the other at 95Hz. (very easy to do if you are aiming for 80Hz and your knob has 30Hz at one end and 300Hz at the other) Let us also say for this example that we are trying to play a 60Hz signal to our subwoofer(s). Amplifier A - 3000 Watts, crossover set at 65Hz. When playing 60Hz the output signal is going to be 164.3 degress out of phase with the input signal Amplifier B - 3000 Watts, crossover set at 95Hz. When playing 60Hz the output signal is going to be 101.7 degrees out of phase with the input signal So the two amplifiers are 62.6 degrees out of phase with each other at 60Hz! Okay, so what does this mean? This means that your TWO 3000 Watt amplifiers ARE NOT putting out 6000 Watts TOGETHER. They are only putting out (6000 W * SIN(62.6deg)) = 5341 Watts. Want 659 Watts FOR FREE? Get a CC-1 and set your crossovers properly - Tony D

TD - epic.

I just blew a snot bubble when i read this. .......

The DD-1's input impedance is between 100k Ohms and 50k Ohms depending on which "gear" the autoranger circuit is in. If an amplifier can't handle a 50k Ohm load, it's not an amplifier.

Im gonna meter my farts when I get home. I bet it hits a 100db if I meter at the taint /sphincter, leg up outlaw style.

that wouldnt happen to be DB-r would it? Funny when confronted about it he backpedaled.

Playing music with the car off gets you all the bitches.

Many class D amplifiers make some buzzing type noise when the output signal is clipping, or close to clipping. I believe it is mostly the giant output inductors they all have.

I can see the reply now,"well Steve used the newest version of Sundown amps. We were talking about v.1 or v.2 amps. We is smart."

oh and not to mention, the Xover says "30 -----300hz" please tell me how you plan on hitting 80hz (or 90 or whatever you use) without a CC-1 I mean there is other ways but i bet 99% of the people just turn it to where they THINK 80 (for example) is. Good luck on that!

oh wow the amp still works..imagine that lol

Just wanted to share a few pics of what i hooked up today. The amp is sitting on a 14v XS power battery at 14.6v ish. Rumor had it that the DD-1 causes damage to a Sundown amp and i am here to say that is complete HOGWASH and just that, a RUMOR. I bought this Sundown amp just to show that it is 100% safe. I will post a new pic every few days showing it playing just fine. I will let it play for an hour or two every day for a week straight if i have to. The DD-1 has been used on the smallest nano-amps to the largest amps on the market juiced up at 18v DC. Every brand including Sundown. It just does NOT cause damage. I used a CC-1 to calibrate the crossover as well. I actually did make a video but the external mic i bought for the GoPro did not record any sound....i messed up an entire day of clips. Remember, if you want your own Distortion Detector - hit up http://www.wccaraudio.com and use SMDDD1 in the coupon code - save $10 bucks! We are out of CC-1's for another 2-3 weeks due to a problem with parts being stuck in customs.... thanks!

Well then Steve , your doing it wrong.......

No one is calling you a liar. And I don't know you, BUT, I know someone that can find you, and get to know you better than you know yourself. No way I'm saying your full of it, but, let be known, this crowd HATES liars. Good luck with the build.

day 2.... still works.

I saw the other thread too asking about the score. You clearly have no idea what type of battery bank you'd truly need in the real world. just another dream thread here. I'd love to see pics with your name and date on them of your current setup.

This entire thing seems dumb. You actually metered the truck under the hood 6in from the turbo? lmao Your gonna spend an extra 6k bucks so you can turn your truck off? With 10k in my truck and doors open you cant hear a damn thing when I turn the wick up. And these Powerstrokes aint quiet. That escalated quickly..lol

How will the alternators help hold the s system with it off? It seems like such a waste of money send time. Do dual 350s and whatever you can fit under the hood with four 3100s in the back and keep the car on. The money you save on not buying 19 batteries will more than cover the cost of gas to keep it running.

Ok, thank you. I was also told by a "authorized" repair facility not to use a dd-1 on a Sundown or I would void his warranty on the work he did.

Mmmm overkill. 24 batteries and 3 alts for 10k. I do like it.

I want pics

great, now i need to find someone with a cc-1 to. "sigh" it just never ends with the what needed list when tony d and steve are talking. you guys do some great work, i just need to hurry up and move to the lower 48 so i can find someone i can pay to dd-1 and cc-1 my setup.

This is why we love you, Tony!

The DD-1 is a well engineered piece of test equipment. If used the way Tony and Steve have described in their tutorial videos, you are not going to damage your amp. However, you cannot take the instructions from a single example video and use that procedure for every possible install. For example: A head unit line output of 2V running into an amp with a max line input of 5V will work and is idiot proof. However if you have an active EQ or line driver that can output 8 or 10V, the amp inputs can't handle that high of a line level voltage, so you need to set the line output differently. In this case, you need to set the EQ/line driver using the "through the amp method". Steve has shown this in a couple of videos. This will set the output of the EQ/line driver to the maximum safe input to the amp. Then once this is done you adjust the amp gains. If you don't do this you can feed to much line signal voltage into your amp. This could damage the amp inputs as well as make it impossible to obtain an undistorted signal at the amp outputs no matter what the gains are set at. The DD-1 is not at fault for someone not understanding their equipment and how to use the tools correctly for their install.

oh "ballpark" is probably ok with one amp....but imagine a DVC sub with an amp on each coil. I will take "exact" in that case. Even if they are in the same chamber....hell, even if they are not in the same chamber. Same thing for door speakers. If you have a 4 channel, its pretty important. I wouldn't want one door at 90 and the other at 225. Its easy to be THAT far off.

Ermahgerd guys did you see the part where the amp blew up!? No? Me neither

still is not accurate. Being accurate isn't that important though with a single bass amp. I wouldn't worry about too much until i had MULTIPLE bass amps. Then, i want them EXACT. That's where the CC-1 shines. Its not "ballpark". Its exact.

Hey Steve, Want to warn you, that I've read from a couple smart people that using that tool on that amp will cause it to blow. You better be careful man! Your welcome.

You need to bring this up to my St Judes show in NY. Would love a demo!!!!

Not my video, but it is my truck. 1 xl 18 m1 4th order bandpass.

Is this also going to be a part of the update?

taking nominees for first person to get bant on new software

guys - as soon as i get through the craziness of releasing the vm-1, i will order up what we need to do another run of vu-din. It won't be long. Thanks!

Crazy loud!! Great job Keith!!

Crazy loud!! Great job Keith!!

i vote for 1 8in type r on 400 watts with a set of kicker coaxials off of factory HU power.
