Yaris Sedan Deadening and Sound system upgrade

[sqcomp]

On the RTA...

You'll want a pink noise track.

Place the microphone at ear level.

Mute all speakers except one (tweeter for instance).

Get the level on the speaker to read fairly flat across it's listenable major bandwidth on the 1/3 octave.

Write down the levels on each band.

Mute that speaker, then switch to the other side tweeter and repeat.

Match the speaker levels for the pair using the measurements from the first tweeter.

Once those two match, mute them both and move on to the next speakers, repeat the process for all speakers.
