It's the 15 pinned IC. That's the one I'm trying to recognize.In the bottom picture, the device on the top edge of the board in the middle could be the amplifier. It appears to have 15 pins, however the picture is not clear. I have seen audio amplifiers in that package before...
What numbers, if any, are written on the front of the device? That will be the best indication. Also, there is only one other chip (IC) on the board, what part number is written on it?
Is that the information you were looking for or is there somethings else?
Yes, it's for someone who uses a motorcycle. That stk has a sil package. The one on the board isn't in that package.I'm going to guess that it's a stereo amplifier that a friend of yours uses on their boat or motorcycle, and it's supposed to have 25W per channel output.
The only audio amp IC that I know of offhand in a 15 pin package with 25W per channel output powered by a single supply is the STK4432.

Take a look at the attached datasheet.
It has a suggested layout for a stereo amplifier. Printing that portion of the datasheet and comparing it to your existing amplifier may help a good deal to validate whether that is the amp IC used in your amplifier.
It could be... it's the same package.I just happened to run across one from STMicro, the TDA7374, last week. Someone brought me an old BOSE Wave radio that I openned up in the hopes of fixing it.
