I'm certain it is. Previously I raan two subs off it (RF) and ran two kenwood 6x9s off the RF amp. I only had one pre amp on that head unit so the 6x9s would be distorted and never sounded right. Then I came on these boards and heard from pretty much everyone that RF aren't good subs.
yea you cant use the 350d, if i was you i would get the focals for the front they are very exspensive speakers and dont require as much power as you will use your rf amp 2 power everything
yes but he already has an amp for his subs, he is looking to power a pair of 6x9s and a pair of 6.5 components but only has a rf 200s 100rms x 2 at 2 ohm
