I just hooked up my stereo and my amp is not working. The light doesnt come on and my sub doesn't work. There is power going to the amp i checked it with a volt meter its getting 12volts the fuses are fine and i changed them as a precaution and still nothing. I know this is a very general question but any help would be great thanks

Re: Amp not working
My friend your amp could be getting power that does not mean that it is working.the power only goes to certain point but because your regulator or other related component is defected your amp power supply will not work until the defect is corrected.take it to a tech and have your set repaired.good luck.

Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.
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.
the problem sounds like your new sub is drawing to much power and your amp can not handle it. bridging the amp is a good way to get the full power out of your amp. But it isnt always suggested, my solution is to get a bigger amp. I install stereo systems for a living, and i tell my customers that it is smart to get an amp about 100 more watts then the rms rating of your subwoofer.
Try hooking up a different signal input to your powered sub, another
stereo or even a dvd players audio output to the sub will work for a
test. Just make sure the subs gain is down before starting. If it
still not producing sound, the subwoofers amplifier is bad. I hope this
if you are sure its the amp. the problem is internal. but if your not sure, try a different stereo or source of sound to the inputs of the amp. if there is still no sound than it is the amplifier and it could be a number of things.
hi, your amp seems to be getting power but the cables might be wrong so it's not getting enough power. the light on the amp should be green if everything is going well.
are you sure the cables are suitable for your amp?
