Converting An Athearn Blue Box GP40-2 to sound...

I have done about 3 Athearn GP conversions to DCC, and thought Id take a different approach to this conversion. Instead of just putting a plain NCE decoder this time I want to try and equip it with a Tsunami sound decoder. I have seen some people show their Athearn geeps with a sound conversion using a MRC, but I want to know if anyone has done it with a Tsunami and I was wondering if it would fit. I was thinking about putting the decoder itself in the radiator fan section and then the speaker behind the cab in the filter area.


Decoder I want to install-

Well I did not see anything about doing this in the video but here is a link that might help if you have not done the install yet.
