Side x Side of Sundown SAZ3500D and DD Z2HV

On the other hand that sd4500 reminds me of the old Z1 power supply...very nice over built amp

The Z2hv has been clamped on a 10 sec burp and did 12735 @ .82 ohm and 13.5 volts...this is not rms voltage but I would say 8000 watts rms should not be a problem

i believe it, but fir daily where talking 1%thd.. i just don't see 8k... @17 its likely, but those amps aren't built for it..

the orginal z1 was nice despite the problems... the newer amp are made for those short burps..

next time set your meter to min and get your readings after the discharge(couple seconds).. you will see how inefficient they are..

im not knocking DD, im just tring to steer this guy in the fight direction..

id imagine hes not worried about 1%thd,but for music the dat, mmats, and SD are excellent choices...

Everyone should use this clamp :

As far as clamping power in-car goes it is the way to go... it ignores the initial spike and then reads a few seconds in. I use it for all of my testing.

Example (clamping 4500D in my Jeep):

http://www.sundownaudio.com/misc/_AMP_POWER/4500D/CIMG2529.MOV

4870 @ 1.18 ohms / 12.25 volts

Notice how the final power number didn't pop up for a while.

That is part of my "Uniform Clamp Test" thread... where I set all the amps at half gain to compare them in the same environment.

SD what brand FETs you use?

IRF in all the SAZ Class-D amps -- power supply and output (except for 1000D... has DNI in power supply).

SAE-1200D has IRF / Fairchild.

SAX multi-channels use Sanken and DNI parts.

i paid a bit under 500 for her
i thought the saz3500 was huge, then i put the z2 next to it and was like dayum....

I always and I mean always wait at least 5-8 sec before I take the reading and nobody runs their amps @ 1% thd period.....If I took the intial spike I would have some crazy numbers LOL
