lol u are jokes. we compared the 2 and thats what we got.

z1 actually likes a lower load. something like 0.15 before the rise is good.

yah z1 does heat up and it does suck balls for daily. but we are not using these amps daily so.....

500.1 is not a true 1 ohm board, its more like 1.2 ohm. at 0.7 after rise that amp will clip like no tomorrow. it needs 1 ohm or higher to work properly.
