Glasswolf, No I'm not sure I need that much power. I have two 6.5" MB Quart component speakers and two 6.5" coaxials. I just want a clean, crisp, and powerful sound without hearing the speakers struggle for power. What do you think? thanks.
if the kx800.4 is a bit steep look at the 600.4 its rated for 75x4 and should be plenty of power for the MBQ components far better than the 13x4 of the head unit
