So my brother purchased this amp for his F30 and had it tuned for an after market sub in trunk. His car was totaled last year and it's been sitting in his garage so I borrowed it!! I need it to go back to factory settings as my Bav Ghost subs are not working with this amp I have 0 bass does anyone have a file on hand they don't mind sending me. Or better yet explaining how to get the setting back to normal.

You could try tuning it yourself or go to the Helix website or look for forums
that support Helix audiotec fisher amp/DSP they are widely used.

This is an 8 channel amp I can't see how anyone would tune out the under seats.

Or maybe you could just ask Bimmertec for Bavsound speaker file.
You will have to download the Helix software to be able to do anything
with the turning as it uses special files for the tuning and of course
the tuning software that you can get at there website.

Good that it' the Bimmertec version of the Helix amp as it's not locked down
for tuning like the Bavsound Version.

Thanks buddy I'll look into all that. I think he might have used it as Mids under seat. He had an image dynamic sub in the trunk and says it's for sound quality. Not sure I like the big bass in my cars usually. This one I want to keep my trunk.
