I had the model below the one Dave listed for about a year. I had the M610, I think Simon (fst4dr) has the 630 in his SVT. I never had a problem with mine, and sold it to a Mustang (still works as far as I know) to buy a JVC Dignifine. I loved the sound and the D-Bass function was right where I wanted it. Level 1 for normal music and 2 for "DAMN! WTF was that?!?"
