good point forgot about a line driver...well so far i think i am gonna go with the alpine iva-d310 i like the picture the best and the pulse touch is sweet and if the 2v preouts arent gonna be that big of a difference from the kenwood ddx7017 and the eclipse avn 5435's 5v...it seems the alpine would be the way to go...i still have about 3 weeks before i can actually purchase a unit so more suggestions and pros and cons will be appreciated thanks guys this site is extremely helpful to young guys like me with not much knowledge or experince....keep the posts comming
