I too was looking at this one, the quart and also the rockford prime R1000-1D for about $250, but ultimately went for the re audio 3000 because it stated 1ohm ratings, which the rockford did not,and the mbquart onyx required 2guage instalation, instead of the 4guage I have
Also that gave me the impression that it is more power hungry and my electrical is not up to par yet.
I know I should have went for 0 or 2 guage,
But that's what I had for now I prob do over next spring if my lights dim.
I realize I haven't finished my big 3 wiring to the alternator and engine but that's next.
I just got a kinetic 600 after reading up that caps are a waste of money //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
I realize I a novice at this, but It's a fun learning curve.
