How can avoid interference of radio stations in the amplifier?
Well if it is a humming noise (also can kinda sound like a turbo whining)
its more than likely a bad ground on your headunit or amp check that the amps ground is put on a solid part of your cars metal and get some sand paper and get the paint off before u ground it
other things to check before u go out and buy a filter is
check that the person who installed your stereo/amp DIDNT run the POWER for the amp next to the RCA leads or speaker wire this can cause alot of interferance too and isnt recomended at all .. power wire should be run on the other side of the car to the speaker wire and rca leads
if that fails to rid the interference you can go to anygood car audio store and ask for a filter for the rca leads and also a ground and power filter to elimantae annoying interference
also check that your airal is grounded correctly to the body of ur car over time it can become loose or corrode
hope this helps

try: a shorter ground cable, a bigger ground cable or sanding the surface where you make your ground. a lot of amps will tell you the ground should be no more than 3 ft and for any the shorter the better

Pb1281x pyramid crystal 2ch mosfet amplifier 1600w
You did not say what you have the amp connected to and what the impedance load is. It is only stable at 4 ohms and if a lower impedance is connected, say 2 subs in parallel, it would try to produce more power when you turn it up and would most likely blow the fuse. 20 amp sounds right for the amp. The power rating of 800 watts per channel is peak power, not RMS, and many low-end manufacturers tend to state bigger numbers in the ratings.
Hope this helps.
