As all of you know the original SMD Tool Map was no longer being update by the OP. I went ahead and transferred all the data from his map and copied them to a new map. The new map is on a different server because it is 100% free. We can also add a logo to the top right corner of the Map. I didn't want to add the SMD logo without permission from someone. The new map can be found here: SMD Tool Map If you have a tool that you would like added to this list either PM me or add it to this post and I will add them to the list. I am on here at least once per day sometimes more. I do not feel I own this list, If someone has a better mapping site or would like to take it over just let me know. I will send you the Excel file of all the information. Thanks Dan

I was just wondering what happened to the release date for the dd-1s I put in an order at http://skyhighcaraudio.com and the 150 was taken out of my paypal but now the Expected release date is May 14th 2018 and earlier today it said the 12th ???? Were there simply too many pre-orders? I'm not trying to wine or rush it as I don't need mine until near the end of this month anyways, just wondering what happened.

I have been wanting a dd-1 for months now but when will they be in stock? Or any good alternative osci-scopes that are under 200 and worth a damn? sorry for posting gen I wasn't sure what this qualifies under

Let's kick it old school with a 20yr old Kicker "monster" amp, the 500ss. This amp pre-dates the ZR1000 and was available in 1996 for an MSRP of $999 USD. The 500ss is rated to deliver: 250x2 @ 4 ohms (500x1 @ 8 ohms) 425x2 @ 2 ohms (850x1 @ 4 ohms) Let's take a look at this amp and see how it performs on the SMD/D'Amore Engineering AD-1 Amp Dyno. Thanks to my buddy John for lending me the amp to test. See it on YouTube in 1080P HD or embedded below:

Hello Everyone, It's been awhile since I've been on the forum, but I'm in the midst of my new audio build and I've run into some issues. I'd really like help to problem solve these issues. I'm running an active 2 way front stage and a 12" sub in the rear. First things first, here is a short run down of the parts related to my issues: H/U= Pioneer 80prs. network mode. internal amp off. running directly to my 4 channel amp and sub signal to my monoblock. 4-chan amp: Jensen Power 400.4 rated at 75w rms @ 4 ohms per channel monoblock: Hifonics brutus brx1600.1 First issue. I was beginning to set the gains on my amps, but when setting them I can only seem to turn the gains about 5 to 10 degrees above minimal gain before distortion on both amps. I'm using a DSO oscilloscope to see distortion in the signal. On the 4 channel amp, I measured 4.9v from the deck and nearly 17v out of the amp. Does that sound right? The math seems to check out. 17v on a 4 ohm load gives 4.25 amps equalling 72ish watts. Is it normal to only turn the gain knob a few degrees? Issue two. Stick with me for this one. Since the 80prs' high frequency outputs lowest setting is about 1.25kHz, I used the midrange rca's to set the gains for the tweeters and mids. I used a 100hz and 1k Hz test tones at 0db , -2.5db, and -5db. During this test is when I noticed an issue. I had the drivers side speaker wires unplugged from the amp and all rca's unplugged except the driver side mid rca. I had that plugged into channel 4 which is set up to be the driver mid. (note: channels 3/4 share a gain and 1/2 have a gain, so 3/4 are mids and 1/2 are tweets.) When I played a 1k Hz tone into channel 4 (driver side mid) I heard an audible, but low volume tone out of the passenger mid. I played pink noise to test and I heard an even more noticeable static sound out of the passenger mid. Now I might be wrong, but if the rca for that channel is unplugged, shouldn't that speaker be completely silent? Just another thing, I left all the gains where the scope showed clean signal, where I left it was set using a 100Hz -2.5db tone at max headunit volume, and playing music at max volume the sound is what I would call regular driving volume. It is not loud. You can definitely talk to the passenger with the volume at max. There should be more volume. In the previous build, I had the same amps and a pioneer avh double din and the gains were set by ear. That system got so much louder it's laughable. The last build the gains were set at around 75% with no audible distortion. Now they are at around 10%. So I'm curious, bad amp? bad scope? Help, Please.

Well guys finally starting my build i got the subs in and the wood just trying to figure out how to do this box i will have pics on the design tonight i am just having trouble with the port. XS power D3400 Coming in the mail soon and not sure on what amp yet ether crescendo or DC I am Thinking 3000 or 2000 RMS not sure yet.

anyone selling a DD1?

anyone selling a DD1?

Ok, so I have a Pioneer AVH#### head unit, and the volume it distorts at is 37. So when adjusting the gain on the JAD 1200.1 I can max out the gain on the amp and still get no distortion, but even when I have the gain all the way up and put the actual head unit into distortion above 37 I still get no distortion from the amplifier. I do notice that when adjusting the gains I hit tiny bits of distortion but it quickly goes away. Could there possibly be an issue somewhere with the amp? Has anyone had any similar issues? Note that I have 2 of these amps and I get similar results with both of them. I know it may be a slim chance both of them would have the same problems, but you never know.

Hey guys, I had a question that I can't seem to figure out on my own. So for four years I ran an Alpine 1000 and an Alpine 50x4. The Sub amp I set with the DD-1 to -15db and the 4 channel I set at -10db. Subs were a pair of Kicker CVR's and they lasted the whole time and still looked good when I sold them. I upgraded to a Kicker DX1500.1 and a single Soundqubed HDS315. I set the new amp at -10db while I was breaking it in. I also have a Double Din Pioneer head unit that is clean at max 38. So, here is my problem. I broke in my new sub and was ready to set to -15db as I want as much pounding as I can get. So, I set the amp to -15db and everything is clean and looking good from the DD-1 but when I take the volume to around 31-33 the sub sounds like absolute shit. Not quite distortion but almost like it sounds like it's reaching it's mechanical limits or close. Like it's being pushed too hard. I know the amp is overpowering the sub by about 400 rms at max power which I would hope being a clean signal it can take that. I don't listen to anything slowed or chopped. I checked like 3-4 of the main songs I used to slam with and they are all normal levels around -5db to -6db so nothing too hot level wise. Also, at -15db the sub starts to smell after a short time so of course not wanting to cook it I turn it down. I have yet to really hammer it and am hoping that the smell is just the newer glue getting heated up for the first time. Any ideas on why the -15db setting is too much for this set up? I was concerned the amp might just be putting out dirty signal but the DD-1 shows her clean at 38 on the deck and -15db playing off the DD-1 CD. I'm just at a loss. The volume difference between -10 and -15db on this set up is immense and I really want to keep the -15 setting. Thanks ahead of time for any responses and help I can get on this issue.

DD-1+ Demo Video

Does anyone around north east Georgia area (athens, commerce, toccoa, carnesville, or even in anderson SC) have a DD-1 that i could "rent?" I only need to use it once for my sub amp (no mids and high amp) . not really rent but pay to use once. id rather not buy one right now cause of low funds after buying a new amp but i would like to tune it right. Thanks in advance. Greg

so im tired of having problems with gains and stuff not knowing if im clipping or not so my questions is should i invest in a dd-1 before i buy a second battery? is the dd-1 worth the money?

Looking for a pre-owned DD-1, maybe someone wants to upgrade to DD-1+. I asked previously and didn't jump on one so have to ask again. Thanks

I recently found a really nice old school Punch45 on eBay. Here's the guts I also connected the amp up to a resistor bank at 4.14ohms and did a power test. Source was an Alpine CDA-9851 using the SMD DD-1 40Hz 0dB Test Track. I tuned the amp with the DD-1 and was able to max out the gains with a clean signal from the Alpine. Then I turned up the Bass Boost knob until the signal started to distort, according to the DD-1. As you can see on the amp's cover, its rated at 22.5W/CH @ 4ohms. It lists 35W/CH @ 2ohms so bridged @ 4ohms you would expect 70W. Well, here's the bridged output to the resistor bank: Measurement "P6" gives a clean 95W! This little guy is probably capable of more output since I just quickly wired up the resistor bank with alligator jumpers. I also used some simple wire jumpers to tap into the molex plug for the speaker outputs. If I got a proper molex adapter and thicker wires to improve the loading connection, I'm sure she'll do more.

New to car audio, so as of right now, I have front components 150 w rms @ 4 ohms in the front and coaxials in the rear 70 w rms @ 4 ohms. I want to run both front and rear off a 4 channel amp. Problem is I want full power in front, and obviously less power in the back to protect from overpowering them. How should I set the gain in the back to prevent overpowering them, also wondering can I use the DD-1 to test for speaker distortion? I know you use it for testing amp and HU clipping but what about if you're overpowering your speakers? Cheers

I was wanting to find someone in the western Indiana eastern Illinois area who has a dd-1 or anyone who has other ways of setting the gain on an amp I can pay if someone has a dd-1 to set the amp. its set by ear right now I'm a little under half way though my build and before I go and finish the amp rack and false walls I was wanting to fine tune my amp. any and all help would be much appreciated

Another quick test of an Old School Alpine head unit...this time the CDA-9815. It's from around 2004, so not REAL old school, but still pretty old in terms of car audio gear. The 9815 has the internal V-Drive amp, claiming 60w x 4 output, we don't verify the output of the amplifier, we are just concerned with the pre-amp voltage output and THD. I test once with the internal amps ON, then once again with the internal amps OFF. Do you expect a big difference? Do you expect ANY difference? Watch the vid to find out... http://youtu.be/Fza-1zludTA (^^ for some reason my video link is not embedding as a video?)

Anyone in N.C. area (preferably Piedmont Triad) have a DD-1 that I can make use of? I'm in High Point.

Hey everyone, I know I've been here a while, reading topics, and joking around the random, and such, but since I've got some things done, I thought I might as well make a build log. 1st, here's my car Now, my equipment My tiny little amp, the MB Quart FX1.600 And my Kicker CVR12 that I got from a pawn shop for $60, it's alright. The JVC is something random, not gonna use it And this used to be my former setup before coolant destroyed the box. It sounded terrible anyways Now time for the good stuff: 1st off, here's a design I got from RAMDesigns, 2.3cu ft tuned to 33hz before displacement Some supplies Some red suede for box wrapping I got for free Everything all cut after the help of some friends, and a very kind carpenter, he even let me borrow his titebond premium

I have always set my bass and mid/high amps using the 0db tracks with the DD-1. Only recently have I learned most people don't do it this way. I have just set my gains on my bass at -5db but have not tried it full volume yet. Provided the voltage stays up is there any risk of damage using the -10db track?

We've got the AD-1 Amp Dyno very close to production trim. Here are a couple of demo videos showing some of it's capabilities. Currently the AD-1 Amplifier Dyno is the only self contained test system that can measure RMS Continuous Power and Dynamic Power of both Full Range and Bandwidth Limited (subwoofer) Amplifiers in the world....and it does it in YOUR CAR! Please enjoy these two videos. The first video demonstrates the gain setting capability of the newly developed DD-1+ technology built into the AD-1. DD-1+ allow the user to make variable gain overlap settings in 1dB increments, even if the system is dirty and reads over 1% Distortion BEFORE clipping. The AD-1 amp dyno's DD-1+ technology can also be used in EXACTLY the same manner as the classic DD-1 if the user chooses. Link below The second video demonstrates the dyno loading and precision power measurement technologies in the AD-1 Amplifier Dyno. Learn about Certified Dyno Mode (which the Jeep's system failed due to headunit's noisy output), Uncertified Dyno Mode (which is the backup in the event you run into a problem like we did), and Dynamic Power Mode which measures power output during a very short term "bursted" signal. This is the industry standard for measuring "Dynamic Power" or "Headroom". Link below

so I dd-1 and cc-1 my 2 fi btl 18s running at 4 ohms since I don't have charging system in my Silverado to run them at 1 ohm. im running them off a mtx te1501d wired with 1/0. Anyways I did everything to the T on instructions as far as I know I crossed it at 80hz and my amp gain is almost all the way up without clipping and head unit was measured as well but I have been using it since thurs and at high volumes I am starting to smell my speakers burning and im wondering why since im only pushing these at 4 ohms with a little over 600 watts and it shouldn't be clipping, what did I do wrong. when I did my head unit I set settings to flat I did everything I was supposed to.

SOLD

Anyone in the DC area with a SMD DD-1/CC-1? I eventually would like to purchase one of each but I would like to meet up with someone and tune my amp gains and crossovers. Or if you know of a buisness near by the DC area that has this equipment and does tuning that would be helpful. Thanks for your time! SSgt. Jason Nelson Andrews AFB, MD
