I'm almost positive that your ground wire on the amplifier is loose, check the connection to the amp and then check the connection to the ground on your car, make sure it is tight and corrosion free. If this doesn't work, make sure your ground wire is of heavy guage ( thick). make sure that the ground wire is not any longer than it has to be. Keep in mind when it comes to ground wires the bigger the better. Make sure you have a healthy ground on the car (bare metal or the frame itself). Hope this helps. Shane (vmax33)
Possibly dirt, or dust in volume control.

It is a variable resistance. As you turn the volume control from low to high - or press buttons to do the same thing on miniature electronic items like mobile phones and MP3 players - the resistance of the volume control is reduced so that a higher current carrying audio waves can get through to the amplifier and so to the item's loudspeaker or headphones.
The average cost of a Crown amplifier would depend on the model. However, they would appear to mostly cost about 300 dollars but they can go as high as 700.
no. input impedance is low & output impedance is high
Look up "op amp" on wikipedia, there is a good drawing near the bottom right. An op amp contains a differential amplifier as the first stage, but has multiple following stages that provide amplifier near ideal characteristics of high input resistance and low output resistance (it can drive more current than a single dif amplifier stage).
To make low volume sound into HIGH volume sound.
You connect your audio leads to the 'aux' input on the amplifier, and the other end to your 'headphones' port. Don't turn up the volume too high on the computer, it will distort. Set the computer volume, so that distortion doesn't occur and then control the volume on the amplifier.
Your amp is probably to small, get a bigger amplifier and it probable wont do it
If a volume knob has a high resistance, then the radio's volume would be low because more of the electrical signal would be resisted and not reach the amplifier and thus not reach the speakers.
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.
As much I know, the quality of sound or let say music depends not only on the quality of speaker as well as on amplifier also. A good amplifier allows the user to play the music on phone on high volume without distortion or disturbance.
Yes, you can plug an electric guitar into an acoustic amplifier. But I would suggest that you don't play at a high volume for a long period of time of the difference in impedence - an acoustic guitar (and bass and vocals) is low impedence, where an electric guitar (& keyboard) is high impedence.
Yes. The "275W" is the maximum power that the speaker can handle at its input. The "120W" is the maximum undistorted power that the amp can deliver in the loud spots with the volume wide open. So the amplifier will never overdrive the speaker. The impedances of the speaker and amp-output should match. If one of them is marked "4 ohms", then they both should be. If they're not the same, then . . . -- the speaker may not sound as 'crisp' as it should. -- the amplifier may not deliver as much undistorted power as it should. -- the amplifier may not run as cool as it should. -- with an extreme mismatch and extended loud spots played at high volume, the amplifier may even be damaged.

an amplifier, where the resistor and capacitor get coupled to provide high oscillations hence by which amplifications increases at high degrees
An amplifier amplifies the small input signal to a high signal without changing its freqency.
A common base NPN amplifier is used for high frequency applications as the base minimize oscillations at high frequency, separates the input and output. In a common base NPN amplifier the voltage gain is high, relatively low input impedance and high output impedance compared to the common collector.
