You should produce me a picture of the guts???//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

I should produce you a picture of shut your cocksucker Chase:crazy:

OPS, I just realized that the amp did 2908.5W, and not 2856W, the correct current number is on the meter on the pic, ehehee.

And the real eff on this test would be 83%... //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I am still puzzled How you get so much power from such a small amp. . . Some things are left to be mysteries

woah.. mounted directly to the heatsink.. cool cool

No mysteries...

The power supply on this amp works at 160V, it is a H-bridge output so all the power supply voltage is applied on the load (except for the losses, obviously).

The output FETs are rated at 90A 200V each.

Why it did 2900W at 11V? It is because it has a PWM power supply so the microprocessor reads the input voltage, detects that is low and send wider duration pulses for the power supply FETs, and by doing this the power supply produces more power at lower voltages.

Why you are on here Murilo I have a question. Being that I do not do burp vehicles, I have to deal with alot of rise. To combat that I have had to wire all my amps down to .3?, assuming imp rise/box rise I would set somewhere around 1 ohm to 1.5 ohm. Is it okay to run these SD amps down, otherwise with rise you are not going to see the power

No, since each frequency is associated to a certain impedance, the overall impedance of your bass range (example: 20-80Hz) might be near the rated impedance of the driver.

We only recommend this for competitors, since you play a fixed tone and the impedance wont change.

Anyway, SounDigital amps will make around 75% of the power at the double of rated impedance, so at higher impedances they still will be powerful, sometimes even not noticeable by ears.

Thats pretty nice
