[QUOTE="i2ain2thunder, post: 8415893, member: 631331"] Sounds like you have a 2 channel amplifier Sounds like you are only using 1 channel for the subwoofer In this case, you are only really using 1 RCA. Both the RCA's should both work on whatever channel you have the sub on (right or left) Sounds like ur using your red channel so both the RCA's should plug into red and the sub should produce sound with either one the exact same. What you've done just recently is you have bridged your amp. Some amplifiers are not made to be bridgable, basically using both channels for 1 sub. You need to make sure your amplifier can do bridged, at the ohm(s) your sub is configured. When you bridge u will be getting twice the power from before when you were only using 1 channel. It definitely sounds suspicious that you may have 1 channel that is faulty on the amp. Try hooking the sub to just the left channel, then just the right channel, it should hit the exact same on either channel. If one channel doesn't hit as hard you may have a bad channel, and i would recommend to not bridge and to use the other channel. Of coarse the overall problem is still probably an electrical connection issue, if a channel is bad on the amp, it could've gone bad due to improper use, or electrical. [/QUOTE]
