So I recently isntalled an Infinity Basslink systems- and it works great- that is for CDs only. I own a 2001 X5 nonDSP with Business CD. I followed the isntructions on how to add a sub to stock radio on the home page of X5 world (http://www.xoutpost.com/articles/x5/s...ctory-amp.html)

When I play CDs the sound is great- No complaints..the basslink kicks really good and its not too loud for people on the sidewalk to hear but loud enough for me to enjoy.

The bad news is that when I try to tune to a radio station..its very staticy. Especialy more when the bass hits. The sound coming from the speakers is real scratchie. Any suggestions?? Oh Yeah, I also used a line input converter to get RCA cables to the basslink instead of connecting speaker levle inputs. And when I diconnect the RCA cables the reception is 100%.

Could this be that I need to adjust the levels in my line output converter?
