Question about Sony XM-2150GSX Car Audio Amplifier
Lets do some diagnosis.. if it's possible, try hooking another known good sub up to the amp and see if that works. if it doesnt, it's an issue with your amp. if it does work though, it's an issue with your sub. or the wiring. if it's a dual voice coil sub, make sure you've got both positives hooked up to positive from the amp, and both negatives hooked up to negative from the amp. if you've accidently got positive from the amp going to positive of one voice coil then to the negative of the other, and the negative from the amp going to the negative of one voice coil then to the positive of the other, the voice coils will be pushing against eachother cancelling eachother's movements out. and this will fry the sub. OR the sub is already fried.
