Prolly mostly becuase they are trying to run a 4-6K watt amp with no electrical backup. First gen Z1's had their own issues which were fixed on 2nd gens. Z1a's had few very few problems to my knowledge of anything. A few because of vibration but thats what 150+ dbz does to anything. Have not heard any problems with Z2's at all. I am sure someone else will chime in with all the DD haterz around.

Any good amplifier can be damage by user error, low voltage, or just plain abuse. I've seen a Z2 with holes burnt through the board because it was used as a competition amp.....

The designs in the DD amps are the same as most of the amps out there, same parts too, nothing special, they just have a nice looking heatsink. That being said they are all "good" amps, the reason you see them blown for sale is 99% of the time from vibration damage and the owner doesn't know this, he thinks it was low voltage or whatever, which is LOL, every one of those type of amps I have EVER worked on had legs broken off the mosfets from vibration. The other reasons is that they cannot repair those amps themselves (the owners) because the output driver board blows and they have no clue how to fix it because the numbers are scratched off the IC's on the board, and even if they know what the numbers are they don't know how to do surface mount soldering. That and the repair cost on say an Z1A for example is around $500. They just don't want to pay that much to repair the amp so they try to sell it for $200-$400 and let someone else get stuck with the $500 repair bill.

I never had any problems out of my Z2's. I also had the proper battery bank to feed them. Getting high power amps is only half the battle, if you don't feed them they won't perform. You gotta pay to play.//content.invisioncic.com/y282845/emoticons/suave.gif.858fc102f7646e678ee8af7e1fbc41d1.gif

Just a matter of time till you do. The vibration is what destroys them, not the under-voltage... It would have to be severe under voltage like below 9 volts before the amp goes berserk...
