Hello,
Just started tuning my first car audio and this is probably a very noob question. Does my measurement via RTA look weird? It's almost completely flat from 20Hz onwards.
Setup:
ECM8000 RTA and BOMGE BMG22 for audio interface.
RTA is connected to Input #1
Output #2 loops back to Input #2
Output #1 is connected to my car DSP through RCA "in" ports. DSP setup is default meaning no EQ and no other filters applied.
Sound card was calibrated (see screenshot). Pink Periodic noise with full range setup was selected (see screenshot).
I have also tested Sine tones at 1,000 Hz and the RTA picks up that signal just okay.
Any help is appreciated.
