February 26th, 2007 01:41 PM #1Mga experts,
I had no problems with my audio system, until last week. Whenever I rev the engine of my car, the amplifier goes OFF. Ung green light nagiging red. I would turn off the stereo for a few seconds, then turn it on again and the amplifier would work. When I rev the engine......patay nanaman. What could be the problem???

You amplifier might be getting into auto protect mode.. check your gain settings, might be too high, it shouldn't go over 1/2. 1/4 would be an ideal setting.

July 16th, 2007 03:04 PM #7bro. sad to say but i think ur ampli was already busted...try to bring it to ur trusted techincian to check it...to make sure that this problem will not happen again...check ur HU and ampli wiring connections, i think it's better kung direct sa battery ung power supply ng ampli mo w/ correct fuse para safe...

try m lang sir pacheck ung ampli bka yung regulator circuit nya ang may problema nasesense ng protection circuit na over voltage ang input due to increase voltage galing sa alternator,maybe the regulator transistor, capacitor or zener diode ang papalitan pwede rin faulty protection circuit sensitive na siya.

Your Apms cuts off at high volume. Check the following on your system.
1. Your input sensitivity may be set too high. Adjust it.
2. Is there adequate ventillation around the amp to carry off excess heat? If none, relocate your amps.
3. Do you have the bass control on your receiver or EQ tuned all the way up?
Is the loudness on too?
4. Consider using a thicker wire.
5.If you running a 2-ohm load, is your amps designed to handle it?
6. Or you may have a bad ground. Make sure the ground wire is solidly connected to the metal chassis of your car.
