looking @ MSRP $2799 - and there will be some brands being tested but i have to get my test bench loaded with 12, 14.5, and 16v batteries so i can supply a decent amount of power in different voltage situations to the amps. The bench test is great for over all power output testing, but your car and the shitty stock alternator on your 2000 watt sound system, and finding those faults which cause the amp NOT to make its power, and what to do about it, is what the Dyno is about.

i avoid doing installs for people like the plague - too much liability. I don't wanna touch other peoples cars really LOL this is understandable.. I can imagine a line of the vehicles waiting in front of the shop to get the job done.. damn that would suck, unless i had a crew to do the work for me. I am a good foreman. I can't always be the chief AND the indians....normally i am

well go ahead and keep clamping then, the Honey Badger doesn't care what you do. It only cares about its next meal.

I have comcast and I get discovery its the Science Channel and it is on Comcast...don't blame them because you got the basic package :D

In all seriousness though, hopefully your favorite local install shop will pony up for one and have "dyno days" where people can bring their vehicle in, strap it down to the dyno and find the weak links in their system. We really believe this is going to be a great tool for dealers to show people why REAL copper wire is more expensive, why REAL amplifiers are more expensive, etc. The old adage "you get what you pay for" is pretty accurate when it comes to mobile audio. Of course there are always exceptions to the rule, but when a 50 foot spool of 1/0 awg wire only weighs 10 pounds, something is horribly wrong.

I merged 2 threads and things got a little screwed up lol So I added Johns first post to his right here : This is the official thread for the Tahoe build off we hope you enjoy these builds as much as we do! So we are doing a little friendly competition between Sky High and DC Audio. A few things fell into place and we ended up having GM SUVS dropped off at the same time so we decided to make some fun out of it. Rusty, his team, and DC Audios build will consist of the DC Audio Yukon 4 M1 LVL 6 18s with the aluminum baskets. 4 DC Audio 5Ks and a B pillar wall; just to name a few things. The Sky High's Tahoe will have 6 Lvl 6 m2 18s with aluminum cone and 4 DC 10ks in a B pillar wall. Rusty and I (Jon) will be both posting pics along the road to crushing every other Tahoe on the west coast. DC Audio and Sky High have a pretty good and close knit relationship if you guys did not know. This is a friendly build and we are only out to have fun and get some recognition out there for the amazing products going into the builds. So please enjoy the builds and your input is greatly appreciated. See you at Lake County Car Audio with both these builds for the finale!! And Mine starts here - So Alot of you might remember the DC Yukon, Well its at the shop and were going to wall it. Not 100% sure what the plan is but for right now I just removed everything so i can start to measure out the shell. its got for gear (well before I took it all out) (2) 175.4 (4) 5.0 (4) M1 Lv6's (2) Alts (2) Strong Stinger 2150's, The rest of the 2150s are dead and will need to be replaced. The Yukon sat for a while and the battery's are now toast So Im not sure if it will go flat wall, clam shell, 4th order, 6th order. Part of it will depend on the square footage we end up with. On with pics of my progress today

Alright guys, I am all done hearing about "clamping". The numbers generated from that are so far off and don't account for many factors. I just did a quick little dyno run vs the clamps tonight to show how drastic the error is. If you want to know more detail about why clamping doesn't work, there is another video on the D'Amore Engineering youtube channel that describes the problems in detail. Clamps vs Amp Dyno vid here: Detailed explanation of why clamping is wrong vid here:

Tony Candela of CE Auto Electric Supply, Juan Rodriguez and I decided to do some testing with the AD-1 Amplifier Dyno to see what effects adding a capacitor to your system does. We did over 60 Dyno pulls with a Rockford T2500-1bdcp, without a capacitor, with a 1 Farad electrolytic capacitor (a real 1 F), and a 100 Farad carbon supercap. Test vehicle is a 2013 Jeep Grand Cherokee, 5.7 Hemi, 180 amp alternator, single group 49 AGM battery, all wiring 1/0 AWG copper. We tested each possible combination 3 times just to make sure our numbers were consistent, which they were. Video part 1 is continuous power testing, video 2 is dynamic burst power testing. Enjoy!!! Video part 1= Continuous power testing (uncertified dyno test mode). We do 4, 2 and 1 ohm dyno runs with no cap, 1 F cap, and 100 F cap. All tests in this video were made using the Uncertified Dyno Mode which is a continuous sine wave. We test a Rockford T2500-1bdcp in car, with no added capacitors, then with a 1 Farad aluminum electrolytic capacitor added, and then with a 100 Farad carbon supercapacitor added. RESULTS: No Capacitor: 1499 Watts RMS @ 13.07V into 4 ohms 2059 Watts RMS @ 11.84V into 2 ohms 2366 Watts RMS @ 10.83V into 1 ohm With 1 Farad Capacitor: 1489 Watts RMS @ 13.10V into 4 ohms 2024 Watts RMS @ 11.90V into 2 ohms 2358 Watts RMS @ 10.87V into 1 ohm With 100 Farad carbon supercapacitor: 1531 Watts RMS @ 13.13V into 4 ohms 2208 Watts RMS @ 12.25V into 2 ohms 2606 Watts RMS @ 11.30V into 1 ohm Engine RPM held between 2200-2500 for all tests. 1F capacitor didn't add any power on the continuous RMS test, actually lost a few watts probably due to the increased number of wire connections. 100F capacitor added more than 10% more power on the continuous RMS test Make sure to watch part 2, dynamic power testing (burst power). Hint: The results are different! --------------------------------------------------------------------------------------------------------------------------------------------------------- Video part 2= Dynamic burst testing (Dynamic Power Dyno Mode). We do 4, 2 and 1 ohm dyno runs with no cap, 1 F cap, and 100F cap. All tests in this video were made using the Dynamic Power (Burst) Dyno mode which is representative of musical peaks. We test a Rockford T2500-1bdcp in car, with no added capacitors, then with a 1 Farad aluminum electrolytic capacitor added, and then with a 100 Farad carbon supercapacitor added. RESULTS: No Capacitor: 1543 Watts RMS @ 13.80V into 4 ohms 2550 Watts RMS @ 13.32V into 2 ohms 3154 Watts RMS @ 12.76V into 1 ohm With 1 Farad Capacitor: 1613 Watts RMS @ 13.98V into 4 ohms 2666 Watts RMS @ 13.60V into 2 ohms 3426 Watts RMS @ 13.35V into 1 ohm With 100 Farad carbon supercapacitor: 1620 Watts RMS @ 13.95V into 4 ohms 2616 Watts RMS @ 13.65V into 2 ohms 3260 Watts RMS @ 12.91V into 1 ohm Engine RPM held between 2200-2500 for all tests. 1F capacitor didn't add any power on the continuous RMS test, but it OWNED the Dynamic Burst testing!! 100F capacitor added more than 10% more power on the continuous RMS test, but less than 5% on the dynamic burst test.

saw this at the show yesterday. pic of one side of the wall the amps i came in about 10 seconds into his run

I didn't like how "square" it was so i decided to round off the ends some to give it a cleaner look.

i work.

Let me say this a different way . . . Tony, thank you for proving to the world that 1 + 1 = 2. However, a lot of guys currently believe that 1 + 1 = 5. So, it's more convenient for them to continue believing that 1 + 1 = 5 versus come to the realization that 1 + 1 really isn't 5 at all. So, even though it's obvious that the foundation for the thinking that 1 + 1 = 5 has been proven to be unstable, it is still possible to build upon that foundation.

looks nice. i actually kinda like the yellow stitching, but i know somewhere some idiot would see that and try to compare it to a kicker comp.

Somebody will put it online...

Tuned for sure, I start my chemo soon so I'll be watching everyday lol j/k

Thats all I got done today, Tomorrow I will get the rest of the upper panels out in the front of the truck, Drop the headliner 100% make sure everything is matted, Wood arrives Monday so maybe Monday/Tuesday Night start putting the shell in

Thanks =]

Hopefully turns out decently loud

Hmmm so now to come up with the box type, a battery rack and amp rack then its finished. lol if only it was that easy =]

I almost felt bad about cutting his custom suede headliner but then not really.

Back Seats out

Amps are now out

How to pull 4 Lv6s and a big ass box out by yourself lol

OK, i think it is going to be episode #5 - "Power Junkies"...so i will let everyone know when i know for sure. Here is the link to the teaser for the original show that is already airing overseas

I guess it's not on THIS episode but one coming up...try again on the next one. False alarm for now but this is the right show! I had a feeling this one wasn't the right one. Stay tuned, it will air soon i think!

Damn you comcast this is one of the few things on tv that I would enjoy. Hopefully the episode ends up on the internets somewhere.

really liking them kicks!

Quick question when did you did the clamp run: you got over 100vac from your multi meter which seems awfully high. Are we sure this was clean power and not clipped? I know there will be a bit of a difference, but something seems off if there is THAT much of a discrepancy. If I do a simple vPtP to vrms conversion on your voltage reading, the numbers make much more sense. And I didn't see an oscilloscope when doing the clamp test. And comparing a reading from clipped power to one of clean power isn't a very good comparison, hence why I ask the question.

Just clamp and divide by 3 lol

they make them especially for this product.....but we are working on an easy, affordable solution....one that WORKS good. I need it too because i used standard resin to do the kicks and waiting 20 minutes for it to setup was TORTURE. As soon as i pulled the mold from the car and was able to work from my bench, and bring them to the sunshine (when i was ready)... it was amazing again. SMD SUNFLASH FTW. 1 minute at the most with a nice intense sun. I am literally holding it in my hand and it is hardening in place. Its especially nice when some of the glass was trying to pull up and i push it down with my finger, while its in the sun and bam, it locks up like it was meant to be. Not only that, but you can grind and sand right away. The smell is about the same while working BUT...once the SUNFLASH sets up, it stops smelling by like 80%. No lingering odor. I am waiting on my labels from the printing company and as soon as the 72 is done, i am gonna release the first batch! Stay tuned and thanks!

Someone post up the shops business number and let SMD ass rape them for that install
