Hello all,

I am in the process of looking for an amp /dsp as well as subs for my 2020m340i and I’m looking for help with a few things.

1) trying to figure out whether Im meant to use match UP7BMW or matchUP8DSP

2) for those of you who have got the audiotech match amps instead of binmertech how did u deal with the increased signal and pdc sounds? I’ve heard mixed opinions on whether the ASD needs to be turned off or not depending on whether an Audio tune is used to mask the frequencies that the indicators and pdc and gong uses.

I prefer not having to alter oem coding because I have warranty still and don’t want there to be anything that can be used against me.
