Actually, unless your system is totally dual mono, complete with separate volume controls in separate chassis, then the grounds are tied together. Even in a complete dual mono system, I would be surprised not to see them tied somewhere together.
It is possible, but highly unlikely, that you will have a problem. Keep in mind that stressing those RCA jacks can fracture them and that will indeed cause you some serious headaches. So, be careful with the electrical tape, it isn't two dimensional!
