I just opened my stock radio and found that is built by matsu****a
so probably means that the radio is Panasonic. I began removal of each part until found the TA8239H by toshiba,the power output of the radio.I need the pin configuration for this IC piece but don't know where i can get it.In this site is showing the specs but not the configuration,needs to be a member...."yike too xpensive"!..........

I have a project for my stock radio., I pretend to hookup a pair of RCA plugs with a little circuit,i got from another radio,to my factory radio and let me tell you is possible i do this in my other ride and works fine and much better than line level converter I just want to localize the pre-amplifier stage to hookup the circuit and is done.Really i don't want to change my factory radio no other radio have the capabilities of carry a 6 disc changer in the same head unit.NOW if somebody know the configuration for this piece,at least the audio input, or a website please let me know i will appreciate.thanx
:banana:

 

As the new owner of a 02 wrx w/ the premium audio package, I'm also very interested in tapping in the the line-level outputs (pre-amp outs) of the six disc head unit. Here is the data sheet I found on toshiba's site you were looking for: http://www.semicon.toshiba.co.jp/td/..._datasheet.pdf

I haven't yet taken out and opened up my unit, but I'm also planning on wiring up an aux. line so I can hook up my mp3 player when needed.

I really like the OEM convenience and theft detterent, but the sound quality is less than "premiun." We'll see what we can do about that.

 

"WOW"! you found what i looking for .......
Now I have work to do and let me tell you that is the first time i see a Power Channel Output with four inputs and a 30kohms.inputs;but now i know where to begin
thanx a lot man,good job. :banana:

 

how does it to hooking up the aux ? I am also looking for info to hook up my iPOD to it. tried FM transmitter, it really sucks.

Can you share w/ me what you have found so far? Also, the data sheet of TA8239H is no longer available. If you have a copy, can you email me? many thanks.

I have a 2002 WRX.

 

Well i see that the page was removed but my project is on the way I was too busy for the last months.
I have the schematic in a cd disc,luck for you,but i must find where cuz i have tons of disc.
If you want to hook your iPod to the radio you can try a CD cassette adapter or best; buy an parametric equalizer with an AUX inputs.
