I have integrated amp which has L/R pre-out. So i want to connect it to a subwoofer. Since the sub will be at seating area, i need long cable (25 ft). My sub also has L/R RCA line input.

Question: Can i use 2 25ft subwoofer cables ( i have several extra ones)to connect pre-amp L/R pre-out to L/R RCA sub, instead of buying a pair of stereo RCA?
