Change all of your cables to Monster, and only need 5 meter Rca's to go to the back. Might also want to check out a 3-way component set up for the front. They sound so much better, and are very easy to install with minor custom work. You may even want to find an amplifier line that you can get amps that will look alike for the install, and maybe a better choice of brands...But that is just the opinion of a 12 year veteran installer.
