[QUOTE="stones, post: 1022925, member: 540734"] Possibilities- Damaged voice coil causing an improper impedance to the amp. Bad speaker wire connection. Gain sensitivity and or bass boost set too high. Amplifier is malfuntioning. Check the voice coil of the sub with a digital multimeter set to "ohms" it should read pretty close to manufacturer spec (it wont be exactly as rated but should be close). Check to see that no one has mess with your amp settings and set somthing too high. If those check out it is possible that the amp has gone screwy on you, I personnally had an amp fail in this manner, it would play low volumes but as soon as you turned up the system and got the voltage flowing it would go into protection mode, the subs were in good shape and the settings and wiring checked out so I brought the amp back to where i purchased it and it was found to be defective. The shop was nice enough to exchange it for a brand new amp at no cost to me and as an added bonus the amp was the newer more powerful model then the previous years. [/QUOTE]
