Audio Systems: 93 infiniti bose, sony xplod, infiniti j30

Question
I have a '93 Infiniti J30 with the stock bose speakers in it.  i have a 52x4w sony xplod deck which i installed over two years ago and i also have an alpine sub with a power acoustiks amp which i installed about a couple of months ago.  everything has always worked fine up until about about two weeks ago when my rear right speaker blew out so i disconnected the wires from the speaker and wrapped the wires around themselves.  then about a week ago my speakers (i believe only on the left side) would make sparatic, but rare, obnoxious squeeking and thumping noises at constant high volumes, even if the deck was muted but still on.  these noises have increased in number and now take place anytime i turn the deck on (they do not happen when the deck is off).  i disconnected my amp thinking it might be the cause but the obnoxious high pitched screams and medium pitched constant thudding continued, so i plugged the blown speaker back in thinking there may have been interference but the noises continued and just happen more often by the day.  I was hoping you might know the prolem and better yet how to fix it, thank you very much, if there are any answers or questions please email me.  thank you.

Answer
Hello Jeremy,
The problem of squealing is caused by the amp boards inside the speaker/amp combo boxes. My shop can rebuild these for alot less then new amp boards. Please contact me direct for info on how my shop can rebuild your amp boards.
