MY EYE'S !! Clamp tested the Crescendo BC3500D on stock electrical, video added

[purplesyrup]

So what have I learned from this?

I am pretty sure, as soon as I confirm an alternator, and batteries, with my box or "barrel" rise I should say, I need to run a dual 1 ohm coil, then realistically with box rise I should be running right around 1 ohm. OOOOOOOR add another bc3500D and strap them, hell yea

Heres the vid

should be done processing in a second.

Just added annotations so you ccan see what hz im playing at the time

those are some long ass burps for a 3500 on stock electrical.....

Been running it like that for over 8 months,

The upgrades are to come. A chunk just got spend on my other car so I will be doing the rest shortly

Nice stock electrical system, apparently. Wonder what she will do with more...

Well, as I found out my barrel rise keeps me at 2 ohms, i need to recone to a dual 1 ohm coil to get me at the 1 ohm I need to be at for MO POWER, I do have that 100 lb, 6000 amp battery sitting in the garage, and working on a 300 amp alt. that should get me where I need to be, but like I said with the box rise, there may not be too much of a difference in power until I get that bastard down to 1 ohm after rise

its bone stock, I ran a run of 0 ga, and have a run of 4 so im using that too, 300 amp fuse (just to be prepared, I could not pop a 125 amp)

The big difference I noticed was when I ran 3 extra grounds off of my battery. HUGE difference, 6 stands of 4 ga. its what I had laying around

OK, my head unit is in and working fine now, so I figured I'd run a clamp test to see if it made any difference at my cars resonant frequency, I am tuned to 36 hz, but my peak SPL in competition is 47 hz. Off of the factory head unit my highest clamp i've ever done at 47 hz was 1,200 watts, which sucked cause im not using any power at my peak hz. Here is how todays clamp went, remember, stock electrical, stock battery up front, stock 150 amp alternator, no big 3. the car was running and idles at 13.6 volts. I kinda rushed through it, I was in my driveway and wanted to only piss my neighbors off for a few minutes, my step son filmed the whole clamp test, but the picture is upside down, I need to put it on the computer and see if I can flip it. The bet part is after the 47 hz blast his saying "The sound is making my eyes hurt" lol

27hz 2,200 watts

28hz 2,184

29hz 2,204

30hz 2,142

31hz 2,109

36hz 1,888

40hz 1,492

I have some box rise that seems to start around 35/36hz and goes through approx. 44hz, I want to re clamp from 33hz through 46hz to pin point exactly what is happening, and see where the power loss is. It was very loud (neighbors like wtf) so after I did 40 hz, I went straight for 47 hz which is around my peak hz,

47 hz 2,200

Now given, when I add a batterie(s) and get my alternator, I will be able to provide the amp with power to make what its capable of producing. So from clamps im getting 1,000 more watts at my peak 47 hz now, so it is significantly louder.

damn.. 2200 watt's at the max.. YOU NEEDA GET SOME MORE POWER! haha im jokin, but i would really like to see what this does on some real electrical since i plan on getting one.. butt that might of made me change my mind haha

Remember man, this whole test with box rise ran at 2.17 ohms and up, which means I was actually putting out 2204 watts, on stock electrical, at 2.17 ohm, This is actually very impressive considering the BC3500D's rated 2 ohm operating RMS power is 1900 watts. So realistically, I clamped 300 watts over its rated power output at 2 ohms on a stock electrical system.

So I spoke with DD audio today about reconing my sub to a dual 1 ohm to counter the box rise, this should put me at 1 ohm operating power with the box rise. The amp would technically be wired at 0.5 ohms, but it would be operating at 1 ohm because of the rise.

Of coarse im not going to do this until I install batts and a big alt

[8ight]

Barrel rise lol. I like your idea of running the extra grounds, I know grounds are a big part of feeding any amp that's why I am going with dedicated runs don't want to leave anything to chance.
