I'm starting my audio conversion. I rarely keep factory audio in my old school Bimmers. Only the new ones. This week, we deleted the DSP amp and wired up the JL 4 channel and mono block amps. The only new equipment added was the line out converter (link below). All other installation parts were items within my stash of parts and supplies. The amps and subs were purchased from private sellers.
