Need help identiifying a chip - Click HERE for Original Thread

An old car stereo reciever broke, so I pulled out the boards and took off the useful components. Still on it are two chips. I am sure one of them is the amp. here they are:

HA13139
Pioneer PA2019A

What are these chips?

Hi soundNERD
As far as I can dig, it’s pretty hard to find a datasheet or any other info on these chips.
You’ll have to contact Pioneer with some smilies.
HA13102 to HA13135 are all power amps.
So, HA13139 is probably the power amplifier, the other one, no idea.
Pictures of the board?

Heres a picture. They were both attached to a metal clip. Didn't look much like a heatsink, but I am not sure. There were no fins or anthing, it just was flat and wrapped around the chips. The amp is probably 4 channel, right? since it is from a car?
Thanks, Mike

I noticed that after I posted the picture isn't too good. If you need to see it better, I can take one with my digital camera instead of my webcam. Also, the chip is the one on the right in the back, and it has 16 pins.

Here it is.

Also, as the thing broke, I tore off the caps and resistors and other useful things, which is why the board is so empty.

Heres just the amp chips:

Sorry thats a little blurry too, too close for my digital cam to focus on. I think it was trying to focus on the magazine in the background.

soundNERD,
since both chips are build to mount on heatsinks, they both could be power amps.
As per my earlier post, I'm pretty sure the HA13139 is one.
The main problem however for you is what to do with these chips if you have no pinout and other data?
Again, unless someone else knows them or has datasheets, Pioneer will be your only option.
