BLown channel?

[Brent1223 10+ year member]

I have an old RF 250 amp, the left channel works fine, but the other channel just makes the sub **** in (and stick out when I reverse polarity).... Anyone know what the prob is? Just too old and blown out, or what?

Thanks!

Sounds to me like a half bad channel. You're only getting half the sine-wave output causing the sub to move only one way. Does the sub stay at it's normal resting position until music plays, or all the time maxed out?

It's always maxxed out...

try reversing the RCA input, then disconnect it altogether. sounds like a bad amp channel to me.

It sounds like you definitely have a blown channel. What is happening to you is very common with a blown channel (or half blown as was mentioned before).

That's what I thought... IT's def not the RCA's... is there any way to fix that?
