to be honest I'm not too familiar with the setup in the svt, but i've done it in other cars. Theirs a unit you can buy that hooks up to the speaker wires on your head unit and it has rca outs on the other end. But from what i've heard the svt uses an amp already so i don't know if this can be done. Personally I can't believe my svt has any sort of an amp in cause this stereo sounds like ass.
