steering wheel radio control problem

[Mid_Life_Crisis]

(help) The steering wheel radio controls in my Speed3 have gone insane. To be more precise, they seem to have all shifted by one. For example, the button to select a lower radio preset now mutes the radio. To change the Mode, I now have to press the Volume Up button. I swapped out the factory amp and speakers (did not cut the harness behind the radio - did cut the one under the driver's seat) so I'm betting that if I go to the dealer they'll cry "voided warranty". Any suggestions?

what did you cut under the drivers seat specificaly? i would suggest putting the wires back to stock (butt splice or wire tap something easy) just to test and see if that is indeed the problem....

and yes with a problem like that and what you did i am sure you will be paying out of pocket at 90+$ an hour plus parts for them to screw the pooch a while and then tell you they have no idea...

I cut the line outs carrying the front signals to the amp and spliced in RCAs so I could connect them to an aftermarket amp. I also cut and spliced into the speaker wires going to the front doors (running wire into these doors is a bear).
The upgrade has been in place for a month and this just started a couple of days ago, so I don't think they are connected, although I could be wrong.
Final, really revolting development, the dreaded "intermittent" word. I forgot to mention earlier that the problem comes and goes for no apparent reason.(bang)

ugh that sucks...intermittent is the worse and i thought it just started after your stereo upgrade... you are using a LOC and didn't just splice speaker wire into rca wire did you?? yeah running wire in the doors sucks but it was worth the piece of mind i was after..... anything else different when it happens? are the controls on the face plate correct? does it always happen at a cold start? how does it stop on its own or do you have to stop and turn on/off the car? do you have to reset the ecu? have you reset the ecu lately?

It comes and goes for no apparent reason. I'm driving along and I change stations or adjust the volume and it works fine. A little later they are confused. It just comes and goes.
The last time the ecu was reset was when I put in the amp & speakers, because the battery had to be disconnected.
