Civic FD stock dash audio unit query....

[oj88]

Just in case you you haven't tried this yet but you can actually turn off or set the EQ curve of the oem HU to flat. This is advisable for those who change their oem speakers and are using the stock oem HU of the FD.

Here are the steps:
1. Press buttons 4 & 6 at the same time. While holding those buttons turn ON the HU.
2. DSP flat will now appear on the screen. Press button 4
3. Turn OFF the HU and turn it ON again.

The volume of the speakers will now play louder.

The factory settings will go back when you turn OFF the radio.

Actually, it will only go back to the default DSP setting when you switch off the key.

I did that for about three months before I decided to upgrade.
