Im amateur at this so go easy on me. I own a OLD Durabrand HT-400 5.1 Surround Sound System. Lost all of the original speakers except the subwoofer (Love that little guy). Im now running 2 Sony Speakers from a old stereo and a 5.25" Peerless India Woofer all on Center channel ( In Parallel i think) and the 6" subwoofer on the sub channel. My friend is giving me a 10" Rockford Fosgate Prime Subwoofer in a Sealed .75cu ft box. The specs say 45 to 150rms on rockfords site. Tho im still a little worried the system wont be able to push it well. Is there a way to wire a plate amp to the sub and use the receiver too or am i screwed?
