[QUOTE="KaeZoo, post: 1605565, member: 554753"] Leaving the RCA unplugged won't damage anything. You might want to adjust the gains and bass boost for the new output level. Fixing the problem requires locating the LOC, then reversing the wires connected to one of the speaker outputs. It's likely, but not certain, that the LOC is placed behind the head unit. Just to give you an idea, you have to double the output power to create a noticeable increase in subwoofer volume. Obviously, you can easily tell the difference with one RCA unplugged; that means the just disconnecting the RCA cable is making the amp produce at least twice as much wattage as it did before. Your first estimate was that there was a 10dB increase in volume; if that's accurate, that means the amplifier is producing TEN TIMES as much power as with both cables hooked up. That should not be happening. [/QUOTE]
