First review. I just got this in today. From what I was told I was the 1st person or 2nd person to own this amp. The build quality of the XAD is superior to the VAD series amps. It just feels more high-end. Not downing the VAD series at all. I absolutely love my VAD27001. I do prefer the sleek minimalistic appearance of the VAD, but that's just my personal preference. We don't buy these things for looks, amiright??
The 12v and Ground will accept 1/0 awg wire no problem. This amp has 2 fans as opposed to my VAD's single fan. Honestly, I couldn't tell a difference in the fan noise. Not to blow smoke, but I think they may have used quite fans in this model. With the VAD there is a thump sound when powering the amp followed by the noticeable fan noise until you get to a nominal volume. 6 in my case. I did not notice the thump and the fan seemed to drown out at 5.
There is only a RCA input, no outputs. So if you're planning a multi-amp configuration, you'll need to plan around that for your set up.
I have 4 VCW 12-V2s wired to 1ohm and it rumbles like a frickin jet engine. I have it feeding them right around 4,000 RMS. I am impressed at how clear it is even at high SPL.
When I was setting the Gain with my DMM, I went over the rated voltage and was pleasantly surprised by the illuminated LED signifying that the amp was clipping. That is freaking awesome and a much-appreciated feature. That should save some people from frying their beloved sound system components.
