I recently just installed my front speakers after they blew. It's actually not that hard to splice the wires.
Just need wire strippers, electrical tape, flat head screw driver and philips. I also needed some needle nose pliers to bend some parts on the new speakers. They had trouble fitting even though they were 6 - 1/2.
I got some new pioneer speakers from Circuit City. 54 bucks. Slightly better sounding than what was originally in there.
The whole process probably took me about 45 minutes to do. This would be my 2nd time changing speakers in my entire life.
