i have the 5 bose system and i put in 4 new type r speakers, a 3000 watt power ackoustic amp, a kenwood head unit and 2 12' type r subs. WHen i the radio is on i get sound to all the speakers but barely any power to the subs. However when i put in a cd or a dvd i get NO sound to any of the speakers but full power to the subs. I kno the factory bose amp has to come out but then where do i go from there? i checked all the wires and connections and they are all done right in the back of the head unit and i checked and played with all the settings on the radio and still nothing, any advice would be much appreciated, i've done many systems but this one is giving me and my friends major problems
