we've had different experiences then LOL...id say an mbquart over an AQ all day other than that i agree totally. the mbquart is superior to aq in every possible way.
You sir need to stop posting inacurate responses. DJ "recommends" to try to stay above or at 1ohm strictly for warranty purposes due to certain people not being I guess you can say, misinformed on how to build the correct setup. These amps will not "Burn up" at .5ohm, given you have the electrical to back it up as you would need in any other situation. Ran AQ amps in multiple setups, both the 2200d's and 3500d's. Both at .5 ohm without breaking a sweat. Hell, I've ran the 3500d at .25 before rise without a hitch.even dj will tell u not to run his amps at .5 ohms it will burn them up.and if you bench them both the quart is far more efficient and does power at lower voltages.
