i have the Cadence Xa175.4 coming in and im going to see how i like it, gonna put it in my girls car does 110x4 at 4 ohm and 175x4 at 2 ohm, seen soom good reviews.
I know the AQ amp is supposed to be better quality, but the internals of it look bare compared to the Quart and Planet Audio amps. Those are supposed to be putting out more or the same power at 4 ohms than the AQ is putting out 2ohms.
