[QUOTE="alwaysat8k, post: 8272496, member: 658090"] I changed my crossover and stuff. Still no change. I am running only one sub right now. I wanted to test my amp aswell to make sure it's working properly. I tested a few things today after buying a clamp. My input voltage at idle is 13.4V. Under mid to high volumes about 60-70% it dropped to 11.96V and stayed steady. I then clamped the positive output on my amp. It came out at 21.1amps. The voltage was 9 on the speaker output. This equaled 190w. Even at 1ohm with less than rated voltage i should be seeing more output then this. I was afraid to turn up any louder as my sub was getting close to bottoming out. It was pretty **** loud though. My gain was at about a quarter on the amp. All levels on my deck are at 0 except subwoofer output, which was at the highest. I'm going to try another amplifier tonight to see what's going on. I'm not entirely impressed with 11.9V but my hands are tied.
