Hey all! Just installed the M-Audio Sonica Theatre into my carputer and for some reason, no matter what adjustments I use, I can't get clear sound from my speakers (I have a 4channel amp driving the front and rears and a single channel driving my woofers) This speaker setup worked beautifully with my Clarion in-dash DVD player and also they worked well when hooked up to the built-in sound board (each pair at a time). Anyone have any experience with the Sonica? I've done searches but no one seems to have run into this problem
