My rockford punch 800a4 is acting up and i don't know what is wrong. Two of the channels work fine but the other 2 only work when the gain is all the way down.

If you turn the gain past about 1/3 one channel will pull the speaker in and make a high pitched noise and the other channel will pull the speaker in and push it way back out again making a popping sound.

Also, when you turn the gain up until the point when it messes up, it dosn't do anything. With the other channels it gets louder. Anyone know how to fix this problem.

 

i dont know wut to tell u, ur amp is fugged. u can completely avoid this by NEVER BUYING ROCKFORD FOSGATE AGAIN. they SUCK SUCK SUCK.

 

Well, I have always liker RF. I'm thinging about replacing it with an alpine 5 channel amp. Does anyone know a model # for an alpine amp with 5 channels that has about 75 watts rms per channel and 150 on the sub?

 

Alpine MRV-F450

i know those RF amps love to over heat, they could cook a burger faster than a George Foreman Grill
