Hi I was just wondering what software you used to tune the ECU? Also, is there any way you could share the tuned .bin and .xdf files? I have looked everywhere and I can only fine the files for the T5s. Thanks a lot!

There are 6 channels from the factory; the front dash tweeters, the front door speakers, and the two speakers on the rear deck. The harness you get will wire the dash tweeters and door speakers together so those 4 speakers are really only 2 channels, and the back 2 are the other 2 channels.
