yeah im so stuck between the two. mb quart is obviously cheaper, but i know for sure i'll get the power and quality with RF but i also know the mb quart is nice.I have personally used rockford power series and liked it. I have also heard good things about the mb quart discuss line, I'd go with whichever is cheaper for you.
what do u have it on???I have the DSC2000 and love it. Not one problem, I've been runing it for a few months now. For the price you can't go wrong.
