With all the screws out finally we can see the guts connected to the back panel. Make sure the power cord is unplugged from the wall before you get into the back of your subwoofer. Once I unplugged the actual speaker from the amplifier board I was off to the garage to throw it on the bench.
A good soldering iron will last you a lifetime and save you a whole lot of money during your repair work. My SA1000 unit has paid for itself many times over. The control and concentration of heat is awesome. I can't believe how many years I had to put up with lesser irons.
