Audio Systems: Wiring two amps, rca input, rca jacks

Question
Hi I'm Damian.  
I want to hook up a separate amplifier for my midrange speakers. The only problem is that I only have one set of RCA jacks already running to my thousand watt amp to my subs. What can I do and how?

Answer
Hi Danian,
I would recommend using a fader unit such as I have in my show car, it's made by Alpine or Pioneer, both good, and has one RCA input and two outputs, you  can then also fade between midrange (2 x 8" on mine) and subs (1 x 300w 10" on mine).
