I have a problem with my inifinity kappa 255a amplifier and believe it is a common problem because it has happened to others. This is a multi channel amp 5CH rated at 4 X 50 & 1X 200. My problem is that the output for the subwoofer channel does not work but the other 4 channels work fine. I know this is common problem because I have read others talk about it online and just wanted to gain as much knowledge about the issue that I can. I'm hoping that someone else out there has had the same problem and could tell me something to narrow it down. Anything you could tell me would be greatly appreciated. Thank you for your time.

I bought this same amp at "half MSRP" a few years ago from Crutchfield. I thought, "What a bargain!!" Wrong!! It was so big and impressive. Whoop tee doo! The amp was great for about 2 months. Sub output, same as all the others. Problem was I had it about a year before I used it, so no warranty. I personally don't think getting it fixed is worth it, considering the cost of comparable amps. Unless of course you can do it yourself. I now have a Hifonics Z8000 with virtually the same specs. I have played the heck out of it for almost 2 years with no trouble. I bought it brand new on ebay for <$200.
