Steve which model did you get the 2000 kit?, man they have lots of kits and different model numbers, kinda confusing. I thought when bridged you could only drive 1 channel, or is that for each board you have?

See my post a few sections back. He essentially bought a modified 2000 kit.

Got a little antsy, so I dragged out my variable AC power supply and dialed it into about 50V AC to test the amps. I will say this... IT GETS LOUD! The sound seems about the same as the AVR-3806, but its hard to say because I'm just running one VP150 at a time. I hit 104db (@ 1m) constant output with the iPhone turned all the way up, and was pulling about 50W. Amp IC temp hovered around 56C (that's the actual chip, not the heatsink which was only warm to the touch). But just as I was typing this mail, the toroid arrived! Will be away for a bit doing some rewiring, but looking real good so far. Pix attached: Test setup: Temperature: Toroid!

Thanks for those links everyone, the Protocase supplier looks like a winner if it isn't too expensive.
That torroid looks pretty tall 6-8", that would allow for alot of room for air circulation around the system.

The toroid is 6.2" diameter, and 3.5" tall.

Wow!, only 3.5 tall those pics do nothing for sense of scale. That makes it really nice for a lower profile cabinet, this just keeps getting better and better

Almost? If the dude sold predrilled cabs, it would be a no brainer.

The M80s acutally got the amp heatsinks hot in bridged mode! I could sustain 102 db, both speakers, from 12 feet away no problem. The amp started going into protect mode (high heatsink temp over 100C) at about 105db sustained (my ears are ringing right now). What the amp does is turn off the affected channel until it cools and turns it back on again. I'm going to do a quick rewire to unbridge the amps to see how far I can push them. Some people had this problem and added to the heatsink and put a fan on it.
The sound is INCREDIBLE! It really does sound punchier than the AVR-3806. Very clear and tight. The wife said it was not even close (she liked it better than the AVR-3806), but it was a bit more close for me. Definitely punchier and tighter sound. If it sounds just as good unbridged with a higher output headroom before overtemp, I may leave it that way and hook the VP180 up now.
