MY EYE'S!!! Clamp testing Crescendo BC3500D on stock electrical - YouTube
Remember this, this amp is rated at 1900 watts at 2 ohms, with my box rise I was at 2.17 and clamped 2,200 watts repeatedly at different hz, Thats 300 watts over rated power on a stock electrical system, not bad, not bad at all.
READ BELOW FOR THE RESULTS
Also the DMM was only hooked up to one coil.
With my box rise, the lowest impedance I have reached was 2.17 ohm @27 hz
I think I need to recone to a dual 1 ohm to compensate as soon as my electrical is done being upgraded.
Heres the results, so remember, this whole test ran at 2 ohms and up,
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
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.
