With my right rear speaker blown I need a replacement for it. I can get a replacement for $20 from Ed Morad but he also has a Bose system from a GTP for only $100 (minus the tweeters). This to me seems to be a good deal without going overboard on a sound system. What (if any) modifications would I have to do to my current system to accept the Bose. Is it just plug and play? I have the CD player with equalizer and 8 speaker system. Thanks for your help and input. (I feel like I've been a pain on this speaker subject.)
