it goes like this.. Jensen > Dual > Clarion.. actually Jensen and Dual are pretty much close.. but really theyre not names i would really trust... Id go with a pioneer or something more known and actually has 24/7 technical help and good warranty.
I got a dual 7" indash in my whip right now.. what model you got? the picture is pretty fuckin clear.. but my remote stopped workin recently.. could just be the remote tho..
