I copied this from another thread, I think it is something everybody needs a reminder, especially now that so many people are using the DD-1 as well as using it as a defense when members on the forum are telling them they clipped their woofer. The DD-1 is a great tool for the average consumer to set gains consistently and accurately. But, a DD-1 is not an end all solution to never clipping your woofers. Different songs are written at different levels, some include clipping from the start and some don't. It is the users responsibility to be "in tune" with their setup and recognize when they are pushing to hard and adjust. For example, I've watched the man Steve himself alter his levels constantly depending on song and frequency. He had excellant attention to detail, constant monitoring of the health of the setup, and he controlled the system variables. I'm sorry (OP of the thread who blew a woofer) thought this woofer was indestructible and using the DD-1 was definitely a good move now you need to refine these skills by using the DD-1 with the right tones (I used 40hz -10db for my Scope) and constantly improving on how you are controlling the system. -Drew **Remember, woofers and amps are stupid. They only do what they are told and you are the bus driver on this road to DBs**

24 out of 32 is a pretty dirty Alpine IMO. also, i never said you WOULD get a 161 i just said What IF. We never claim anyone will gain DB even though we see it all the time i dont get how its dirty? after vol. 23 yes it distorted but everything under that is as clean as you can get if it was a drity deck there would not be countless sq champs that run alpine decks like the one im talking about if you mean its a drity deck if you try to use it at full volume i can understand that but to call the deck drity because you have a point of distortion is not right remeber people listen to ever word you say so with that statment people will be running around calling alpine decks drity when thats not the case anyways we are of topic now my questions were anwsered thanks holy st*t bro are you on one today? settle down LOL goddamn. 23 out of 32 is distorting way sooner then most of the Alpines i have seen so either you'r numbers are off or that deck is dirty SOONER then it should be for some reason. If your numbers are right and 23 is in fact the number, then i'm sure its nice and clean from 23 down. Never meant it was a dirty deck from top to bottom, just dirtier at a lower volume then some of the worst decks i have tried. I had a $99 Kenwood that didn't distort till 33/35 iirc. It doesn't by a LONG SHOT mean thats a better deck though. its an older alpine the newer ones do in fact distort at way higher volumes like 28 of 32 not mad or trying to be a dick or anything sorry if im coming off that way just trying to have an audio convo ive actually learned a couple things here hahah word up bro. Thanks for your input we are all sorta learning together. All i ask from people is we keep it cool because at the end of the day most of us are friends outside of the internet (like me and you).

as far as gains go, the DD-1 pretty much to their spots. But you will run into the same problems setting your gains with an o-scope that you will with the DD-1. Neither will tell you what the music you are playing is doing. You set the gains on the amps to match the maximum non-distorted power coming off the deck. That was the purpose of the gain from the day it was invented. If a song (itself) is a little bit dirty, i don't think its going to make that big of a difference, especially on the woofers. I think you guys are over thinking this a little too much. Knowing the decks maximum clean output and matching to the amps and adjusting the overlaps using the different tracks is the goal. -5, -10 db etc is there for gain overlaps not to over/undercompensate for a potential dirty song. the dd-1 wont do everything, you still need to have a clue on what you are doing. You can still f**k your system up but the chances of doing that drop by 90% if you set the gains the way they were intended from the begining, even if you play dirty songs. According to you guys, everything i have ever played is "dirty" and "clipped" (the song itself) and i never seem to have problems. You should still know your systems limits and pay attention...especially if everything you have is overpowered, like a lot of people roll

for setting gains it did. I will never ever use an O-scope to set another gain in my life.....

only thing I can add is very simple, follow the instructions they were written for a reason. Just like anything else people will try to skip a step here and there and then turn around and blame the DD-1 for their fuck ups.

damn to bad im 2 hours away i would love to jumpup in that!! played everyday at work for 5 years i could forest gump that shit

or maybe he is tired of seeing people diss on the product because it has my name on it. (not neccessarily people here, but in general) i bet 2/3rds of the haters would be on board if it was JUST D'amore on it. 100% of the people who hate me have NO reason to hate me and people that like me are just as sick of seeing it. Well i take that back, out of the 100% who don't like me, some already didn't like me (for no reason) and talked some shit........then when i say something back to them, they REALLY hate me. I can't think of one thing i did to anyone FIRST to deserve some of the negativity i get.

for setting gains it did. I will never ever use an O-scope to set another gain in my life..... of course you wont. its your product, you own one, its simple, and it works. but for someone who doesnt own one or cant afford it, the "old" way still works just like it did before. thousands of people have tuned with a DMM and didnt blow up a sub. thats all im saying. the dmm method is not accurate at all. If you try to set the gain on an amp that is overated and you try to tune it to the watts it claims it will clip. And if you try it on a underated amp you won't get full output. DMM got my 12"s to 151db+. got two of my team mates over 160db. and a team mate's son to 160db no wall. your point is true, its not idiot proof or as simple and im not saying it better at all. it takes some experience to get right and you can mess it up. but it does work and, more over, was highly recommended by many users on this site the day before the dd1 came out. everyone was passing out the chart on how to tune with a DMM to every new member. it just baffles me that everyone seems to have forgotten that they used to personally recommend the DMM method. and to charify so people dont over react. im not saying anything bad about the DD-1. it is a nice, simple, effective, tool and for many users, its the best option. its not quite that good but my JL 4channel does do that. it has an anti clipping feature that kicks in automatically. "the dmm got my teamates a 160".....that doesn't mean it was correct. For all you know they could do a 161 by setting the gains properly instead of GUESSING. With the DMM, how do you know when the deck distorts? Just use the ol' 3/4 of the way trick? FYI: even the shittiest decks i have tried don't distort at 3/4.....some not at all. That is power left OFF of the table. Before i learned how to even use a scope i used to tune by ear, AKA guess, and never had a problem getting into the 150's. Same goes for a lot of people. It worked but didn't mean it was right

would be nice if it could adjust what people think are cool at that time as well. Have like a whats cool setting.. run amps at .5 and will even switch logo's with what ever amp is cool at the moment! Tony D get to werk

Well maybe one day they will come out with a smart amp that will adjust for clipping on the fly no matter what frequency it is at.

thats still not under any real load thanks for trying tho and how is setting the gain at one preset frequency good when box rise rises and falls similar to a frequency response graph set gain at 60 hz, box rise is at 3x. drop to 30 hz, box rise is at 1.25x these are questions i have had for a long time and why i have not got a DD-1 yet if can be set for these issues ill for saure get one

that just means you need to buy 10 more alternators. duhhh

2009 Tahoe 2 Z.v3 18's All pictures from during build. Need to stop being lazy and throw the second baffle on that bish. if you feel froggy one day... and want a setup that with the truck sealed up for demos will crush your spleen...slap together a box for those two 18" with the subs firing forward and port firing into the rear driver corner. EDIT: for those 18's you should have about a 3 layer baffle with some proper bracing... you would see it would get a bit louder ... those puppies are massive.

for setting gains it did. I will never ever use an O-scope to set another gain in my life..... of course you wont. its your product, you own one, its simple, and it works. but for someone who doesnt own one or cant afford it, the "old" way still works just like it did before. thousands of people have tuned with a DMM and didnt blow up a sub. thats all im saying. even if it wasn't my product i would be saying it. The fact its being used in more then one manufacturer's training courses now and replacing the O-scope in the classroom (for proper gain setting, overlaps etc), i am not alone. Sure the oscope has its place, somewhere. For me, at the bottom of my tool box. anyone who tunes with a DMM (to set gains) is wasting their time and FAR from accurate. You might as well guess.

as far as gains go, the DD-1 pretty much to their spots. But you will run into the same problems setting your gains with an o-scope that you will with the DD-1. Neither will tell you what the music you are playing is doing. You set the gains on the amps to match the maximum non-distorted power coming off the deck.

You should still know your systems limits and pay attention...especially if everything you have is overpowered, like a lot of people roll That is what I tried to say. I didn't word it too well. I also left out TOOK in my post. I meant to say the DD-1 pretty much TOOK their spots as far as setting gains is concerned. its all good man i was just adding on to what some of you were saying......and trying to explain why we use -5 and -10 tracks rather then 0db the whole way. Its all about the overlap. If you used 0db the entire way you are not going to get the most out of your system. If you want to use 0db all the way thats your choice i just don't recommend it

If you have a hard time visualizing a clean, soft clip, and hard clip wave this is a very old video of mine. -Drew

Looks like it'll run very reliable. Perfect for the ground pounder types.

Sounds good but I have a question where is your voltage at right now. Even on the MBQuart they should be seeing 600-750 each but they don't seem like they are getting any power.

Whoa, I heard dumbfucks. Well. Your the dumb BITCH who put a expensive ass sub in a garbage fucking box, then clipped the shit out of it, THEN complained about it, THEN tried getting your buddy to sell it, THEN admitted to voiding your amps warranty by running it at .5!!! You are THE ONLY dumbfuck in this thread.

clipping will fuck up a wet dream

Gotts love n8:-) he's on it... and how this guy get a lvl6 and 5k

Thanks for the demo bro, Shit was crazy loud lol......
