APA250... Perplexed.

[jmanpc 5,000+ posts]

I have a Clarion APA250 that I'm using to power my tweeters. It's worked great until about a week ago. My left tweeter went in and out... started going out just a couple times here and there, then it went to about 50/50, and then out more than on. Now, the left tweet is out completely. It might come on every once in a while when I hit a bump or turn.

So, I switched the RCAs and the left tweet still worked, and the right was still out. Then I switched the speaker wires, and the right one worked, but on the left channel. I tried both RCAs on the left channel, and both the L and R RCAs made the left channel work... so I've come to the conclusion that the speaker wires are fine, the RCAs are fine, but the amp's right channel or right RCA input... isn't.

So, I pulled apart the amp. I looked at all the components on the amp, and they all look fine. Nothing's loose, nothing's scorched, nothing looks out of place. I took the board out, and there's nothing scorched or anything on the underside of the board. The amp looks completely fine.

... sigh...

Any ideas?

I pulled the board completely out of it... nothing wrong with it at all. I looked at everything, and saw nothing scorched or anything.

And it's well out of warranty.

Thats odd, no idea what to say man...perhaps your speaker wires are fuxored?

nope, i can make both tweeters work by switching channels.

I'm really tired and this may not even make sense....or maybe I'm confused, but could you try a y-adapter for the RCA on the "good" channel? See if both tweets work?

again, both tweets work just fine. i can make either work fin by switching them to the working channel.

Then your channel is fried somehow...It may be something really small like a resistor that you missed...
