Hey guys I'm looking for a decent nothing insane dc clamp ammeter. I just need it to take basic measurements at work. If its good to like 200amps im cool with that like I said nothing fancy or crazy. If it's decently accurate and works cool. Thanks for the help I went to home depot today but best I could find was 140 dollar Klein meter which is out of the question.

I'm not all to familiar with the new mb quart stuff will they do rated power?

the mb quart might work or the mtx but the zx is out cause he changed subs and needs 1ohm stable now but thanks guys keep em coming

I think he is gonna be around 200 but he may spend a little more if someone has something good used. He did ask a friend of mine about his powerbass 3k that was 350 thats why I say that.

bump

Thats beast

awesome thanks for the heads up Steve

Hey guys had a friend get his zx1000.1 stolen from him. He is not a memeber on the forum but I told him I'd help him out and ask if anyone was selling a good amp at a fair price. At any rate thanks to anyone who can help me help out a friend.

Awesome giveaway Steve so very generous of you. Congrats to the winner you got an awesome prize.

That made sense to me and I use my DD-1 probably like 4 to 5 times a week sometimes that's daily. But Iv'e never run it with a processor. However what you said makes sense in my head cause that's what I thought. Anyone else have any insight and deeje I think the vid was just to show the difference between line level and RCA. I'm taking about tuning with a device that does eq mapping based on freq response that's taken based on the cars environment.

Bump anyone

Haha that's awesome! Tell me which ones, I probably know who they are. On the 4 ch its the Db symbol, the parrot, the beer mug and the skull on the mono its all of the same minus the beer mug. the 'db' is Dave Baker, he is the Engineering Manager at Rockford. The parrot is Richard Dudley, he is a circuit board designer. The beer mug is Mike Myer, he is a mechanical designer. Don't know about the skull. Well let me say this bro I owe You, Steve, Juan and all those guys a round of beers homie. Cause let me tell ya I've never had a car that got so many compliments. with the minimal amount of equipment that's in it. Also the DD-1 is a life saver I love that thing less than 5 mins now to tune amps at work. I can't wait for the CC-1 one to launch cause I hate guessing on crossovers its always bugged me. You guys keep up the great work. Cause its like your company slogan says. It's for the love of audio.

Jville140db DD-1 North Florida 32068 I'll tune for free if you come to me otherwise gas money is needed.

I am hoping someone can tell me this. I have a good friend who wants his car tuned. But I can't for the life of me figure whats the best order to do it in. He has an Alpine touch screen in dash and the Imprint processor which is installed but not tuned. I am wondering what order to use to tune it with the DD-1. Should I run the software and Imprint the car first or should I use the DD-1 to set the amps then run Imprint. I don't know and I was it to sound its best. He spent a lot of money on great equipment and I want him to get the max potential out of the system. If you would like an equipment list I can get it. Thanks for any help in advance and if this has already been asked I'm sorry I searched and couldn't find anything. Edit- Not sure if this should have went here or in the DD-1 section. Sorry I forgot Steve put that section on here till after I posted it.

Awesome info Tony and Steve. I figured that's what it was gonna do when I first read about it. Thanks for confirming my suspicions. Any idea on a street date yet and maybe pricing. Btw Tony I find it funny that when I pulled the cover off my 4 chan and Mono to check out the guts on them your avatar was stamped on the board along with others and I was like well I guess I know who to thank for these now too. I wish I knew who the other avatars belong to though.

Have you worked up a price yet I'm Damn curious

Wish I could but not only will I be working I can't afford to go. But hey have fun Steve and be sure to take plenty of vids.

No prob bro more to come stay tuned

You will be fine with 8 ga for that amp but if you plan to upgrade later run 4ga.

What is the amp and I'm pretty sure he means power wire in which case I would go no lower than 8ga but I dont know the amp so I can't say it won't need 4ga

I went to Installer Institute back in 04 here in Florida and it was good, but now it better bigger facility and more courses. Can and talk to Jason Anderson he will fill you in he is the lead instructor.

Second Test Ok so here goes for the second SMD DD-1 official real world test. So the Equipment and vehicle are as follows. Vehicle was a 2008 Honda Pilot Head Unit- KDC-BT948HD Subwoofer- AudioBahn slim line AW1004J run @ 2 ohms Speakers- Polk Audio Dxi6500 componants in the front and 650 Coaxials in the rear Amps- SSL EV4-1600 and Polk PA880 Wiring and Electrical- Single Run of Kicker Z series 4ga batt to distrabution blocks and 8ga out from the disrabution blocks to the amps. Signal wires were Kicker X series and speaker wire was a combo of factory wire, kicker z series and install bay 9 wire. Sub Enclousure- Sub was custom mounted in the factory sub location Tools used SMD DD-1 Craftsmen DMM Inferred temp gauge Epic160 for spl test I know its not a Termlab but it will show a difference in SPL for our purposes. Ok so as before we used the same series of tests. First tune was done with a DMM. We toook the headunits max volume of 35 and went to 3/4 of that which was 26. after that we tuned the amps using the good old ac volt forumla like in the previous test. Which gave us 14.4 volts @ 4 ohms on the 4 channel which should be 50watts. The mono was tuned at 24.5 @ 2 ohms as to not exceed the subs RMS of 300 watts. So after tuning was done the crossovers were set at 120hz @ 24db per octive and the sub amp at roughly 100hz @ 24db per octive and we ran our tests. The max spl of the system on music was 112db. The temp before tuning was 79.6 on the 4 channel and 81.6 on the monoblock. After the 15 min music test @ 3/4 of max tune volume which was volume 20. The temp was at 85.4 on the 4 channel and 101.4. on the monoblock. So with this test I also recorded the starting voltage and the lowest voltage at any point during play of the 15 min test. Which was 13.1 at the start and 12.5 at the lowest point during play. So I also took note of where the gains were set on both tunes The DMM tune was set at 1/3 on the 4 channel and at a little over 1/2 on the monoblock. So after the DMM test we let the amps cool down and the battery recharge. Than we went to work again with the SMD DD-1. So in this test vs the last we found clipping through the amp instead of the Rca's like on the previous vehicle. And we found that our max volume undistorted was at 33 out of 35. So using the same battery of tests and the same music we set to find out what the DD-1 would bring to the table. The max spl jumped up from 112db to 115db. on music. The 15 min music test was up next so we set the radio @ 3/4 vol which was 25, and with the monoblock putting out more power I did expect a big jump in tempeture since the amp is rated @ 500 watts RMS and in the last tune we tuned to 300 watts RMS. However the results of the heat test were rather shocking. With starting temp this time of 80.6 on the 4 chan and 81.1 on the monoblock. The 4 channel ran up to 85F which was a difference of 1.4F which was a lil cooler and the monoblock did run hotter as expected but it was only 102.2F thats a difference of 1.3F almost nothing given the amp was putting out more power in this test as seen by the spl result. The voltage through out the test also revealed promising results at a starting voltage of 13.1 and the lowest at any given point was 12.8. The gain setting moved as well in our favor as instead of 1/3 on the 4 chan we are now at 1/4 and on the monoblock we went from just over 1/2 to 1/3.

First Test The tunes on the amps were done as follows. The first tune was done with a DMM with the deck set @3/4 volume. You know the good old formula method. The second tune well that was clearly with the DD-1. So what we looked for was max spl on music at tuned volume. Maximum volume of tune. The last was temp of the amp after 15 mins of 3/4 volume of max volume based on tune. The amp used was an old 250.1 lighting audio bolt amp with 2 crunch 12's a stock dodge headunit with a single run of cca 4 ga and a cheap line output converter with no adjustment. So are results are as follows. Tools used Smd DD-1, Craftsmen DMM, a digital inferred temp gauge and an epic 160 i know its not a TL but its just for comparison of overall SPL. The vehicle is a 2004 dodge dakota extended cab with a sealed box and subs forward. Spl was based in lower passenger side a pillar with the drive door open and all other doors sealed. Base temp before any testing or playing 77.6F on both tests. The first tune based on a headunit max volume of 38 we tuned to 28 roughly 3/4 volume. We hit an Spl on music of 130 DB after that we set the system to 3/4 volume of the max tuned which was 21 on the volume and let it play regular music for 15mins than measured the temp at the bottom heat sink of the amp which was 114.6F So than we let the vehicle sit for 2 hour to let all the items cool and to let the the battery recharge. After which we retuned with the SMD DD-1. So with the same criteria we set to work. Well the head unit according to the DD-1 distorts at volume 21 so we backed it off to volume 20. Then proceeded with to tune the gain with the DD-1 which was now at 1/4 not 1/2 as it had been before with the DMM tune. So then we tested max SPL with the same track as before at max undistorted volume which yielded a 134 on the meter. Thats a huge increase of course we were shocked. Then we did the 15 min real world music test in which we set the volume at 3/4 well actually it was 16 out of 20 so 80% volume we ran the same tracks and at the end of the test the amp read a shocking 112.2F. So the amp ran cooler as well hmm. so as I was checking voltage through out the 15 min test I noticed something with the dmm tune we would drop down to around 12-12.4 volts on most heavy bass tracks. After the DD-1 tuning it would fall between 12.5-13.2 most of the time being on the high end of that. So to say the least the proof is in the pudding. The DD-1 does what it says it will and more. The amp ran more efficient. The subs were louder and on top of that the electrical didn't get nearly as taxed for the given output.
