A:Answer You should have no problem after you locate your receiver’s input bank, and subwoofer input port. I’m like you with my family room system (really big TV): I pump audio from any source to 13 speakers and 2 powered subwoofers through a flagship Denon. Your 400w should deliver just fine, especially with power from your subwoofer pulling up the audio it processes. Good luck and have fun! Brian in Colorado
