Possible to code base stereo option to hifi / to get flat full range output?

Hey guys

I have installed an amp and upgraded all speakers in my base stereo e93 2009

However the Base stereo is heavily equalized (reduced bass in front and high filtered in the rear )...doesn't sound great at the moment.

If I have the coding changed to set the stereo as Hifi...is this possible and will this then give me a flat full range output...?

Many Thanks.

Files are different between the Pro Radio and I drive to do this.

Some say an Icom cable is required.

When you recode, you'll go from a high level equalized signal to a low level flat signal.
Make sure you adjust your amp inputs accordingly for the low level signal.
