I have the above stereo running through a GM6200F 600W Amp. was fine till recently all speakers dropped out except the front left speaker and a loud whirring engine sound came through that speaker even with volume off. wierd thing is by turning volume right up the whole system starts working perfect but only for about 5min..

I'd need to know more about the amp, but don't forget, amps are rated as their max power... So lets take a 300W/channel stereo amp at 8 ohms. Ok, it's stereo, so there's 600W But the amp is capable of 4 ohm loads...well, now you can deliver 600W/channel, for a total of 1200W In this scenario, your amp is doing exactly what it was designed to do with those speakers. If you wanted to get the full 1200W out of the amp, you'd have to hook up 2 more speakers in parallel to the ones already there. This drops the impedance to 4 ohms per channel = 600W / channel. Yes, the power is split among the apeakers...300W per speaker into 4 speakers = 1200W so any way you look at it, there's your 1200W
depends on what the RMS is for the subs because although the subs are 1200 watts, there is a minumim standard you have to follow. If you don't atleast run the lowest wattage thru them, then you will most definately damage the speakers....you should also be aware of the fact that your "600w Pioneer-4 channel amp doesn't even push a true 600 watts... Your best bet is to upgrade ur amp, or add an additional amp to your set-up. And you really need to pay close att to over or under running your power to your stereo system because you'll burn out ur altenator rather quickly. Use proper wattage , and you should also look into getting a power-cell which lessens the chances of destroying your altenator and helps to ensure that your stereo system sounds to its full potential.....
Hi, the only way i can see the amp resets the stereo is that power is dropping. The amp should have its own wires directly to power/battery so as to not affect anything else.
On the protect, try to disconnet all the speakers, make sure the power is OK. If it appears to work, the there could be a problem with speakers/cables. Try a different speaker to see if it works. If the problem continues with speakers off, a different speaker etc, then there is a problem with the amp. Hope that helps
If amp is stereo then remove one speaker at a time and check sound quality. Determine if it's one channel or both. If Mono, or bridged, then do same and determine if it's speakers or amp. If problem with both, then it may be amp, but without another set of subs or a scope to test, the possibility that both subs are blown remains. You should know if you pushed it real hard all the time till it clipped, or till the speakers were popping out of their cones, or do you use it within the rated limits, with the system tuned to prevent clipping. If you have been bumping it real hard, maybe suspect the subs. If the amp is acting normally otherwise.
I can not tell for sure without seeing the unit; however, this often happens with stereo receivers when the contacts on the protection relay start to go bad. You can try to polish the contacts with emery cloth or a fiber brush but it is best to replace the relay if you can find one that will fit.

It depends on the impedence of the speakers. Carfull as you could burn up this amp if you exceed the resistance rating on it. Go here on all of the specs of this model of crown amps. http://www.crownaudio.com/amp_htm/xlsspec.htm Good Luck
There are two things. First check the sound settings of the DVD player. It might be putting out a lower quality sound on the CD side of things.
Secondly try to determine if the speaker tweeters are working. Connect the speakers if you can to another sound source. If the speakers are good and the settings fine. Then you have a fault in the amp unit.
