Reply to Soldering technic 1200s

I have a pair of technic 1200's mk2's i got for really cheap, the problem with them is though that they sound really crappy. So i googled and did some researched and I narrowed it down to it most likely being the rca cables, i youtubed some videos and found some on how to fix the technics. They all told me to buy some new rca wires, strip them and then desolder or take out my current rca wires and solder the new ones onto the tables. So by doing this will my turntables sound better? because they sound really staticy and just plain bad right now, one is worse than the other. Also is soldering hard to do? because i would rather learn to do it myself than pay someone to fix it. Or would it be better to go to a professional who knows what there doing? thanks all! and hope you all had a merry Christmas and happy holidays!
