I have a legacy amp installed and it keeps going into safe mode while im driving along....but when the car is parked the amp works fine,can someone help me find the problem ??
i have 2 amps in the car 1 amp powers my rear speakers and the other 1 powers my sub they are all powerd by the same live wire the 1 for the rear speaker stayes on ,but the 1 for the sub goes to safe mode... then i switch the stereo off and then on and it works for a bit then goes to safe mode again....i have 2 amps in the car 1 amp powers my rear speakers and the other 1 powers my sub they are all powerd by the same live wire the 1 for the rear speaker stayes on ,but the 1 for the sub goes to safe mode... then i switch the stereo off and then on and it works for a bit then goes to safe mode again....

Re:
I agree with Techman, But when I was 16 I had a system with the same problem. Car not running the system ran perfectly start the car and it would drop off. Took it apart three different times even added an air induction cowl to keep amplifier cooler. did not change anything. What I did not take into consideration was when the car is on the voltage is used to power lights, coils, computers, and all the other things needed to make the car go and I was using a long run of light gauge wire. When a downbeat would come the voltage to the amp would drop down, and the amp would sense it as a problem sent the amp into protect for a second and back on it would come again. Better wire, Better amplifier, and five alternators later. Do not know if this is your case but it just reminded me of that.

Re:
First thing to look for would be pinched speaker wires,or a bad ground, or a loose b+ wire. The next would be to have the amp bench tested and the tech should bang and tap on the unit to see if there are bad or cold solder connections inside on the printed circuit board assy.

If you bridge the amp and get 1000 watts RMS and that is split going to two speakers then you will get 500 watts RMS at each speaker. If you have your amplifier on maximum gain it may blow your speakers, not because they are overpowered but because you might run into "clipping" issues running the amp at maximum capacity. Just to be safe I would dial the amp's gain down to 3/4 of the way to full gain. That should give you ample power and keep your amp from clipping and running hot.
if it really uses 1200 watts, that would call for a 140 amp fuse, which is outrageous. for that power, if turly approachable, you would need a v8 engine, and midified alternator(s) arrays, and a capacitor.
You need to make sure that the subwoofer leads are connected correctly. It may be that the subs aren't connected properly. That would cause the amp to turn on without any sound coming out.
I researched your amp and it looks like its not even 2 ohm stable :( the problem with these companies is they lable there amps 1200 watts MAX, that means they tested the amp in a perfect enviroment and the amp fried somewhere in the ball park of 1200 watts, your best bet is to save your money and buy a nicer amp that is two or one ohm stable... that being said the best way to wire your subs is in series
this is too close, your speaker wattage is alway's higher than your amplifier's wattage alway's to be safe because the hard pounding will make the speaker work harder, and this will cause your speaker burn out easily, though you can adjust your amplifier anyway's
you have an unloaded channel,so the voltage is exceeding what the protect circuit is supposed to see.you have to connect an 8 ohm resistor across the output of the unused channel.
do not drive a signal into it or you will smoke the resistor.
a 10 watt will do ok with zero signal input
i have had the exact same problem with the exact same lagacy amp that you have posted, put your ground in a different spot or try double grounds in two different spots this should solve your problem here. good luck
i have 2 amps in the car 1 amp powers my rear speakers and the other 1 powers my sub they are all powerd by the same live wire the 1 for the rear speaker stayes on ,but the 1 for the sub goes to safe mode... then i switch the stereo off and then on and it works for a bit then goes to safe mode again....
