Hi, i have inherited an array of equipment and really need some help. to start this is the stuff: yamaha rx-v640rds amp, sugden a25 mosfet stereo amp, athena c.5 surround sound speakers, a subwoofer with no name just says p.5bc-1 made in canada, epos es11 main speakers, realistic super tweaters and finally an array of cables such as cambridge audio and audioquest indigo. Now the issue is when i plugged them all in it didnt really marry up. Like the subwoofer hummed and you could hear the super tweaters. I am a nobe however i love music and want to get this right. Forgot to mention a maratz cd player. Anyway advice if this will all go together or if the things just wont go together would be great. I can take pictures if you want.
