  1. Welding cable is technically fine. As long as it's pure copper, it's just not oxygen free copper. From what I've read, welding wire is more susceptible to corrosion than car audio cable, but I've never tested this myself. Welding wire does go by the AWG scale, and car audio cable is oversized, so if you need 1/0 awg car audio cable, 2/0 welding wire would be the same size and about the same amp rating.

    Man that is some solid advise! Thank you. I did try the Duracell battery and got the signal light to light up. Still no 40hz detect or distortion light, but a step in the right direction. I will try changing around the inputs and setting it like you mentioned. Will keep you updated. Thank you.

    Try also using a 1000 hz tone to see if you get different results

    Unfortunately the CD player does not work on the head unit so I have had to download the test tones. I’ve tried 0db 40hz and -5db 40hz. I’m going to try a Duracell battery in place of the energizer battery tomorrow. Should I just set the head unit and lc7i to 3/4 and adjust the amplifier gain until it lights up distortion? It’s weird but on the speaker outputs coming from the head unit and the lc7i,  I can’t get it to show distortion at any volume, but im sure it is distorted if I had speakers hooked up.

    How do you have the Lc7i hooked up? Are you sure you're sending all frequencies through it? 

    Have you tried to find max volume with a 1000 hz test tone? 

    If you're getting your high level input from someplace that the OEM unit isn't sending a full signal to, you might not be getting 40 hz through the equipment. Let's say someone is getting their high level input from factory tweeters. Well, the OEM system isn't going to send all the frequencies through that speaker, so the LOC won't get it either, thus making it so the DD-1 doesn't detect it. 

    LOC's like the Lc7i have multiple inputs so on complex stock systems that send different crossed over signals to different speakers, you can take all those, feed them into the LOC individually, and the Lc7i will sum up the different frequencies to make them one cohesive...... unit I guess you could say. 

    Also, when we set the gains in my buddies system with the Lc2i, we had to set the accubass first as well to compensate for the bass roll off. 

    If I'm not mistaken, in the DD-1 manual, or says turn the gains all the way down (I could be mistaken), but I've had good luck with just barely cracking the gain a hair. 

    On another note, once you get it working, set the head unit and LOC gain using a 0 db tone, then set your overlap just on the amplifier

    Dafaseles, yes I did use a name brand battery, as far as the crossover settings on the amplifier,  I turned it to 100hz as advised and the subsonic all the way down.  Would the volume need to be set separately on the radio, lc7i and amplifier separately?

    Are you using the 0 db 40 hz tone to find the max volume of the head unit and set the gain on the LC7i?

    You can actually feed them 3k rms from a taramps smart 3k and the evl will take it all day. 

    Done in the right conditions, right enclosure, electrical all the way correct, gains and crossovers set perfectly.... maybe. But I'm not going to give someone the advice to throw that kind of power at it because if they end up blowing the sub because of over powering it, I'm not going to warrantee that shit🤣

    Old thread back to life lol.

     

    What orientation should the fans be? All blowing air in, or half blowing in and half pulling out?

    I didn't read this while thread, but I've watched the YouTube videos that Steve has used the fans and it seems he'll put fans on one side blowing in, and the fans on the other end blowing out. 

    A good one to watch is of the Tahoe. Old ass video when he's first building the under the enclosure amp rack in his garage at home. The way he gets air to flow though the different sections is a really good lesson in my opinion

    Tried to find my specific issue via forums and google but no dice.

    If I test my headunit (Pioneer 80PRS) for distortion via rcas everything works as expected and I end up with vol 57/60 showing clean.

     

    I tried testing via the alternate method, through the amp and I can't get a signal or 40hz light but the distortion light does come on at vol 53/60. I've reread the manual and triple checked all settings, xover, filter etc. I cannot get a signal or 40hz light with the gain of the amp all the way down as the manual suggests. As soon as I turn the gain up at all the signal and 40hz turn on.

     

    Should I just go with the headunit only method and ignore the results I'm getting through the amp? Any idea why it doesn't work through the amp as the manual recommends?

     

    Thanks

    I ran into this same problem. I just crack the gain a little bit to get the signal light. It seems to still work as expected

    Please read entire system destroyed by dd1 

    I bought brand new dd1 brand new I was excited I have 2 8k taramps it was hitting 157db before setting both amps to exact same. So I read and watched video on my radio turned down all settings to 0 and on my amp all settings to 0 then took speaker wires out put my leads of dd1 to positive and negative on amp tightened them then put CD in and put on track 8 started to turn radio up the signal light never came on Cause it was broke from factory or maybe a customer returned and they gave to me not sure but I turned all the way up then took everything out and one of my amps was fried completely and the other stays on when i take the remote wire out so every time i get out of truck I have to disconnect duel zero guage ground wires so it was broke from factory i tried to contact Steve on Facebook he doesn't care do not buy this dont it probably happens to 1 out of a thousand and I was that guy and i can't even get my money back or a new one nevermind my amps being blown

    How did a calibration tool..... even if it was broken.... blow your amps? It does nothing but read a signal. 

    Did you have an LOC as well? Or aftermarket head unit? 

    Mine, when I use it, I'll set everything almost all the way down. Volume and gain on the amp cracked a tiny bit. Then I turn up the head unit I get the signal and frequency light. 

    And you where using track 8? Why where you setting your subwoofer amp gains with a 1kz -15db tone? 

    Also you'd need to torn the subsonic filter all the way up, and the low pass all the way down, or it could impede the frequency from coming through.

    Wrong, I still cant understand how people think this or maybe you worded it wrong but the DD-1 will NEVER measure clipping.
    You will have distortion long before clipping is ever seen on an oscilloscope. Once the red light on the DD-1 lights up you hit 1% THD so by the time the wave is becoming deformed on an oscilloscope you are so far beyond that 1% THD that the DD-1 is looking for.



     

    No, I didn't miss word it. I was just wrong. Thank you for the clarification. I thought it measured both. I must admit, I only skimmed through the manual lol.

    Patent came through,.... and he is just getting started. 

     

     

     

     

    "

    Efficiency is typically expressed as
    (Power Out / Power In) * 100 = % Efficiency.
    Our new amplifier technology is reaching efficiency of 533% while playing music or sine waves at maximum output levels.
    At 1 watt of output the Efficiency can be anywhere from 1.3% to 90% depending on energy reserve level.
    That’s how it works. Law defying efficiency when you need it most, relatively poor efficiency when it doesn’t matter.
    US Patent 11,205,955 👍🏽"

     

     

    I just saw this as well and was blown away! What was it, 9 amps to play 400 watts? 😳

    that is pretty neat. Have never seen anything like that. Looks kinda complicated tho, I love the traditional look of a bunch of 0 guage and fuse blocks in the back lol 

    Very complicated. Dude has another video where he goes into depth about how he did it, but I couldn't find it.

    I work on Tesla’s and besides the price they are awesome to drive but the biggest complaint is they list 300-400 miles per charge but because they are so fast and fun to drive you average about 120-180 per charge . These things are fast , I’m not sold on electric cars till I see 1k miles per charge and between 25-35k in price for base model. For me I always pictured electric cars with a motor on each wheel like on the back of the hub so no axles needed  and no wiring all fly by wire , but I think we are pretty far from that a lot of stuff is fly by wire now but no enough still to many wires .

    I've heard the same thing. My cousin used to work for Tesla as well, at the plant in Fremont CA, test driving a lot of the cars before they're shipped out. He said they're fun as hell. 

    I'm not sold on the electric cars either. It takes too long to charge them, and even doesn't it say in the manual to not use the fast charge because it can prematurely damage the batteries?

    The range isn't good enough for me either. I want to be able to drive all day, 16-18 hours at least. Or, 5 minute charging that doesn't ruin the batteries overtime.... I'll concede to 10 minutes if I have to. Also, I'm a truck guy. No, not often to I have a trailer or a heavy load, but I do sometimes. I need to be able to drive more than 150 miles before I need to charge. 

    Also, I'm lucky to be able to own a home with a 2 car driveway, but what about the people who don't? Are they supposed to run extention chords across the sidewalk? 

    On top of all that, at least in California, the law makers keep telling our utility companies they need to shut down their power plants. They're having a hell of a ti

    me keeping up, even now. What happens when all these cars need electricity too? 

    What happens to the batteries after they're spent? I read about a chinese company that is working on a lithium battery that, once it can't hold a charge anymore, they can actually recycle the lithium to hold a charge again. So that's a plus if they can figure it out.

    For SPL setups, tap into the high voltage for the amps would be the best way for big power.  100 amp cable goes way further at 250+ volts as well.  This would have other challenges.  Amp designs and other accessories would need to really protect from current exposure, also need to use something like a pyro-fuse instead of the traditional types.  I'm sure teams will figure this out, though it will likely not make it further unless some kind of standard is made for easily tapping into the power vs what you'd have to play with today (like in that Fiat video).

     

    For doing high power 12v systems, you could always go heavy on Ah batteries to make up for the small DC-DC convertors in an EV.  You plug the car in anyways, run a quick connect to the 12v by the charge port and do a 12v charger as well.  Most EVs and hybrids have 100 amp DC-DC in place of an alternator, so not going to keep up with a sustained high power.

     

    Sound quality is way easier in EVs though.  Once you've sound deadened the vehicle, the noise floor is eerily quiet at speed and many also have the insulated glass.  DSPs are going to be pretty essential with all the factory processing.  Entry level hobbyist doing their entire speaker setup is probably over if that continues into low end EVs, though the sub/amp combo will likely still be simple enough to keep people in the hobby.

     

    I fear that the market for easy car audio integration with large systems isn't popular enough to make anyone spend that kind of money on research and development to figure out easy solutions. I really think it'll die, which sucks.

    Driver technology will evolve alongside is what will happen.

     

    Currently a Sundown sa12v2 will convert to acoustic energy 2 watt out of the 1000W it's rated for.

     

    Ultra light and stiff graphene composites are already starting to be used in audio products:

     

     

     

    I guess at some point many years from now subs will become ultra efficient and audio systems will get loud on way less power than they do right now.

     

     

     

    I agree with you, but I think the days of huge SPL systems will be gone. I feel like with electric cars come ultra efficient, decent wattage (not super high wattage) SQ oriented systems. Especially how auto makers are integrating everything through these gody huge head unit screens. 

    Also, you have to convert (at least right now) the 400 volt battery system down to 12 volt. That's no safe task. For smaller systems, not a huge deal.

    Lol I agree! TeslAs are wickedly fast and have a very comfortable interior but I’ll take a gas car with everything inside flexing from subs as I’m driving over an electric car any day lol 

    I just want my alternator 🤣

    So I have a AC D-6.1200 running 3 way active system in the doors. I am pulling signal off the D-6.1200 line level output to feed a AC 1.300 mono amp for a single 10" JL. The signal level on that output is affected by the input slider position for the Mid/Woofer door speakers. If I set that channel up with a 3db over lap, that is the signal that is also supplying the 1.300 for the Sub. Now how do you get the sub setup to a 8db overlap which has a pot gain?

    The same way. 

    Find your head unit max volume with a 0 db overlap. Any EQ's or whatever before the amplifiers, also with a 0 db overlap. Your highs amp, use your -3 db overlap. Then use your -8 for the sub amp. 

    You can even double check if it's done correctly. Set your highs and sub amp up using the -3, then re-setup your sub amp using the -8. There should be a slight difference in the amount of gain you can give it between the -3 and the -8

    That port is a joke as you describe it, you should list your full box design and pics of everything, your subs are kind of entry level too.

     

    Also relax a bit please, one thing at a time. and a lot of pics.

    I was thinking the same thing about the port, but I don't know a much about box design. I didn't want to say anything about it and be wrong lol
