I thought amp left sub right. I didn’t have, wife did but I thought I saw the connector for it and was looking into your same thought process before I traded my 2001 for 2011.

Wife’s with sub did have the dsp.

I think the thing in the dash is only the remote. The “amp” is also the radio if I recall correctly.
