Re: Sony XM-2002GTR Car Audio Amplifier
I don't think it is a problem. Your amp probably has a power-saving mode being activated at low volume levels. Actually I don't know exactly what your amp is, but this is just a guess, and it could be a plausible one as long as you can get sound without using the amp. If it is so, it must have a function to deactivate the power-saving mode.

check your amp and speakers and make sure their both hooked up 4 ohm instead of 2 ohm because if you have 1 set of voice coils on your speakers they can only be hooked up four ohm and not bridged to your amp because if you keep trying this you will lock up your speakers if the speakers are only 4 ohm than just hook them up regular to each channel on your amp if your trying to brigde four ohm speakers to your amp it will keep going into protect or worst case scenario you will fry your speakers and you can check your ohm with a ohmmeter trust me my brother owns a stereo shop
that amp is only stable 2 about 4 omhs mono the powersupply shut dowm drawing t much current it supposed 2 2 fix this u need a 4omh load mono change speaker config so u get 4 omh or buy amp stable down 2 1omh can be expensive
You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.
