Cool, Il play around with this after work tomorrow. Thanks!

Did it, forgot the code though. Il look tomorrow and post it. What a great mod though, it sounds so much better!!!

Hi guys. I have an audi concert 1 with the Bose system in my car. Do you know if there's also a way to adjust the EQ settings? Thanks.

I have the Audi Symphony with Bose. I tried the EQ settings and it didn't do anything. Nothing pops up on the display. Maybe with the Bose it doesn't work?

No, I have bose, and BTW new code is 74386667. Im very happy with the sound, so much more clarity!

So your saying you held the power button in amd the "5" button in, and nothing appeared. Try holdong them in for a sec or 2, and see if that brings it up. You should get a screen with 55555555 on it...

Thinking about another mod, says it will help the quallity of the stock woofers sound, for those of us rockin bose ;)

SAy to sit in the car listening to a song you know well, have a second person, with an index card, cover up part of the port on the back of the woofer. Supposed to settle down how quickly the little cones vibrate, and make the sounds crisper. When it gets to a point you like it, have them remember that, and cover it with masking tape.

Still doesn't work on mine, I've tried every configuration with the power and #5 button. Just a thought here but I believe the anti-theft is deactivated on mine. When I changed the battery a few months back, I was supposed the put the radio code in, I didn't have to, radio normal with power and all the same presets the same as before after total power loss. Do you think this is why mine doesn't work, like the radio is in safe mode so to speak?

The difference may be the Symphony I vs II. Symphony II does not have the options like the Symphony I
