On my 89 wing, I replaced the speakers with less than an adequate replacements and I,m not happy with the performance. I am going to buy and install some high performance speakers (made specific for my bike) but want to know if I can do anything to get a little more out of the sound system like add a power booster or set the (avc) auto volume control to a maximum level (internally) so that the system sounds better all the time? Can anyone recommend anything to get a bit more performance out of the existing stereo system? Thanks, Dan
