I am needing a low cost head unit to use with my low budget system. I am planning on getting a 4 channel amp to power my sub and 2 front speakers. My question is can i get a head unit with 2 sets of pre amp outs front and rear. And will i be able to use the rear pre amp out to power the 2 channels bridged for my sub? I was thinking about getting the ECLIPSE CD3414G as it comes with free installation gear and has two sets of pre amp outs. My sub is a 10" pioneer premier shallow mount and i plan on getting the MB QUART DSC480 as my amplifier.
