Might have to be friends with terry to see it.
Guess so :/

Links not working? Was the video taken down?

using rope when doing large fiberglass projects.
Explain please?
Also, not skimping on electrical. Build up your electrical first, then concern yourself with subs and amps

i use -10db track, i play decaf and i have zero issues....if the song is peaks at lets say 39hz at -2db if its clean then its not gonna matter if gains where set with -5 or -10db tone, i can play a song that is at -8db that is clipped and ill have more issues then playing a song at -3db thats clean. make sense? it does to me so maybe someone else can chime in.
here is a example. regular gorilla zoe-money man, my voltage drops to 12.2 driving
decaf money man, voltage is at 12.9
why? its clean so i have no issues
What I was referring to was all tracks being clean though. However, not every song is going to peak at the same dB level. You can have Rack City peaking at -2dB, and Money man peaking at -5dB. Let's say you've set your gain with the -5dB track now. Money man's bass lines will come through at 0dB which is the loudest they can be without clipping. However, when you play Rack City and hit the -2dB peak, you're essentially amplifying it past clipping by 3dB.
It'd be like taking a song or even a self generated sine wave that's amplified to the max without clipping. Now go and amplify it by 3dB and see what it looks like (make sure allow clipping is checked). The note will now be clipped by that much more, now giving you a clipped signal.
If I'm wrong and somebody can explain to me why I'm wrong then please do, but this is my understanding of it. I can see where you're coming from though

That's if everyone knows the level of every song that they bump haha a little more work than most people do but I guess I still wouldn't trust the head units increments of dbs but if it works for you and you tested it great
Edit: OOOORRRRR that would be a Great implementation of an smd output meter
the SMD OM-1 can be matched to your output of your system, when using a DD-1.....and you will be able to SEE if you push it further then normal. Coming next week. Maybe TOMORROW!
I haven't heard of this yet, still recovering from some recent purchases haha. Rent in a few days too xD
Is there any info on it though? Just googled it and saw a few pics, I'm guessing it does exactly what I was tryna say and lets you know the exact db level of bass notes in the song you're listening to? If so then you and D'amore really need to stop taking my damn money! Haha good stuff though Mr. Meade!

Jesus I was not expecting such an informative thread when I ran across this...although there are some things I'd like to bring up as well. I didn't like the wording of the DD-1 manual saying how -5db was for SQ, -10 for middle, and -15 for louder. I feel like if you're going to be spending this much time and money on a system you need to know the music you're playing. It may not be very practical, but for the most part I scan every song that I slam/demo with through Audacity so that I know the peak dB level of each individual song.
By setting your gain with a track like the -10dB one aren't you potentially boosting any song with bass notes within the 0 to -5dB range by a good 5dB at least? Like Rack City peaks at 29 and 39hz and does so with -1 and -2 dB bass notes. While impractical for the everyday user, wouldn't it be safer and better to set with a 0dB track and then play around with HU settings and stuff like that to adjust for each song individually?
I'm sure not every headunit has it, but the LP filter on my headunit allows me to adjust the dB levels. I can go from -24dB all the way up to +6dB. So say I find my HU max volume is 45/62, and then set my gain with a 0dB track. When I play a song that peaks at -5dB, I can simply adjust that LP to +5dB and essentially match it up perfectly. And I've even did this with my deck, by checking with the -5dB track with the LP set to +5 and it wasn't distorted. Then I checked with a -6dB track I made in .wav format and it did clip.
I'm in no way ranting about anything here, just trying to figure out if this might be a better way to set gains and all for people who do have a feature similar to this on their HU's. If anybody actually takes the time to read this I am interested in discussing it further if you think I've made a mistake somewhere or anything too, but yeah. Tonsssss of good info in this thread and glad I came across it!

11,777. And LOL at the people who still don't pay attention to what Steve says...
-
Appreciate the video Steve! Means a lot that you'd still take the time to make it even though you sound like you caught something bad. Hope you get well soon we need to see more Amp Test Tuesdays!

I just generated the same tones in Audacity and put them onto my iPod since that's the only thing I listen to. Considering I have a CD stuck in my headunit and all that fun stuff lol. Haven't ran into problems from it

4500. I have faith that this amp should put out some nice numbers

So if im correct that will creat a 2 ohm loadr right?...what do suggest I set the crossover frequencies at.?
Depends upon the speakers themselves, the application, etc. And yes, if you have 8 4 ohm speakers you can wire them in pairs of 2 with the negatives and positives together for a final load of 2 ohms per channel

I don't understand what this question has to do with DC Sound Lab, but it should be fine. I wouldn't put it in the middle of the panel though, probably closer to the edges where it's a big stronger

Came across these old sketches I did when I was cleaning up my apartment, would anybody be interested in starting up an SMD art thread or anything? I'm not a professional by any means but I love seeing what other people can come up with. Art's always been that one thing that I wish I was really good at. Anyways, here's the sketches:

Very nice work on that box man! Looking beautiful can't wait to see what you do to it

-
I'm guessing it doesn't quite do the rated, maybe close at 14.4 and on dynamic burst

Sad day, says the code for one of the 15 is no longer valid. Oh well, time to mail this stinger out anyways!
-
I'll be the first to admit...I stood strong behind my Stinger saying 'oh those people whose stingers stopped working must've done something to break them'.
After the past week of wondering why my voltage went from being a strong 15.0 volts to maxing out at 13.7 on my Stinger and going through the hassle and stress of thinking that either my alternator or one of my batteries got fried to finally figuring out that the voltmeter stopped reading correctly I am looking forward to ordering myself a VM-1.
Will be sending it in within the next few days!
