Hi Guys, I have a query which I'm sure some knowledgeable people on here can answer. I have an old home theatre set up, the panasonic Sa-Mt1 to be precise () Since it lacks any modern connection I'm unable to connect it with other peripherals to get 5.1 surround sound. The speakers all connect into the active subwoofer and then from it I have a cable that goes to the dvd with RCAs (I think that's what they are called) for left and right audio. My question is, can I just buy a new amplifier and connect the sub and speakers to it to be able and get surround sound? Or do I have to go all the way and buy a whole set up (that is, amp + speakers). Many Thanks in advance.
