but it says that they both dont have a sub preamp output. do i need that to install an amplifier and some subs?

Answer 1

(i would get the kenwood)

they both say "outputs: 4-channel preamp outputs (front, rear/subwoofer)" in their descriptions so they do have RCA outputs for your amp

if a radio does not have the output then you would need a "line output converter" (about $20 from places like radio shack) here is one http://www.crutchfield.com/App/Product/I...
