guys just ordered a f90bt .. need a kit to connect it to my 03 hummer h2 with onstar and bose . witch kit would you recomend..

why does one use rca imput the other not .. i am assuming that rca would have a clearer sound . or should i bypass bose and just use the f90s amp instead. what do you thing thanks

PAC OS-2Bose Bose/OnStar Radio Replacement Wire Harness

Metra GMOS-04 Radio Replacement Wire Harness w/NAV output

or Peripheral

anything but scosche (they will work for weeks then burn up and need to be replaced) the metra units work pretty good

bypassing the bose wont work to well, most factory bose speakers are 2ohm, and the factory sub wont work any more, however replacing all the speakers, rewiring the truck, and adding a aftermarket sub is a fun and exciting day
