Instead of the actual sound, a whistling (high pitch) sound is heard from my speakers, whenever a strong bass-beat comes in an audio track. Is this pointing towards the fact that the power supply connected with the power amp is inadequate for the AMP's current requirements. I postulate this becoz there is no distortion of any kind and the audio signal is not clipped in any of the pre-amp/tone-control sections.
The power amp is of a car-tape. I don't have its power ratings etc. However, the circuitry is completely covered in cover-like heatsink.
My power supply is a 12VDC capable of 6 Amperes.
Would connecting two power supplies of 12 VDC 6 Amperes, in parallel, be equivalent to a 12VDC 12 Amperes power supply?
