if i remember right when i had mine the advantages was a single control over multiple amps and as for the line driver side of it i think it could do up to 10volts per amp output......much better than the 2-5volts most decks do. but that will only benefit you if the amp can take that much without clipping. so there is a potential for gains, but sieng that its already a beautifal 160 vehical, those gains might only be in tenths.
