Got it in today. I will be doing some testing over the next few days -- here is a comparison to the 1500D v.2 model -- the new v.3 is longer to fit all of the new parts and the fan but is narrower.

The newer 2500D v.2 and 3500D v.2 will actually shrink in width AND length compared to the old units for reference.

* The fan blows through the board to expel air out the sides of the amp. Will do a heck of a job in terms of cooling :thumbsup:

Little bit of testing in Derrick's Explorer -- using my Extech power clamp meter (which always reads low vs. separate meters method) :

26 Hz
46.6v
43.7A
2036 Watts
1.06 ohm

27Hz
48.2v
40.4a
1974 watts
1.19 ohms

The super low frequency is a bit different than normal testing as well -- I'll get it in one of my other setups and do testing in the more typical range (more similar to my "official" amp clamp thread) when I get a moment but Derrick was up so we threw it in his Explorer! We kept it down below any point of audible distortion for testing.

Time does not permit details testing and dialing in today... just a quick test and we are very pleased thusfar.

Watching my power clamp we saw 1500-1600 watt continuously on music as well. So far I haven't had to fan turn on in any of my testing nor has the case been even lukewarm to the touch.

Also some 16v testing will be done as time permits. We usually squeeze a bit more out of our units between prototype and production as well.
