If adding hi-fi make your output to flat, then there is no point of coding it with standard stereo and speakers setup. As the sound will get flat and there is no point of doing it.

This would only work if you went for hifi stereo with upgraded hardware (speakers, subwoofer) with amplifier.
You don't see the point yet you posted the exact reason for doing this. In my case I have an ms8 which currently I have my logic 7 amp hooked up to the speaker level inputs makes much more sense to have full range low level balanced outputs from the head unit. This also allows me to mount my xd600/6 where the logic 7 amp was.
I was hoping that somebody will prove me wrong and will give me a reason to play with this.
I was wrong.
You have better hardware and reason to play with it, so go ahead.
I only added L7 subwoofers so coding without amp is not going to help me.

This is a bit off topic but adding L7 subs to a hifi system isnt the best idea by itself. The l7 subs are 4 ohm while the hifi is 4ohm so the hifi amp will not be putting much power to them.

Taibanl is right (he meant hifi is 2 ohm) if you just replaced the subs in your hifi system with logic 7 subs all you really did was cut the power in half.

I am planning to put them today, and most of people who have done, gave very positive feedback.

Ok, please report back with your results...maybe make a thread in the audio section...very curious to hear both SPL and SQ differences on the same power source. Maybe install one and then fade right/left with an iphone JL Tools app to compare.

I can confirm that after fitting L7 woofer, bass is more punchy and you can keep sub level at 6 even on max sound without distortion.
I would not say massive difference but difference is significant enough.

Of course the difference is not massive, it just cannot be massive. This is not magic.

You virtually cut the distortion in half -and the loudness as well- by doubling the OEM amp load at the woofers. Your effective bass level is now higher, clearer and deeper -but not louder- at the woofers. However, the overall sound should be slightly louder as the rest of the OEM speakers will be at a higher volume level than the woofers to obtain meaninful bass.

The 2011.5 HiFi OEM amp (silver color) is even better sounding with higher loads at all the speakers than the pre-2011.5 HiFi OEM amp (black color).

Just to correct, I have added L7 woofer to stereo woofer setup.
So both of them are 4 ohms.

In states, all cars come with hi-fi system (woofer is 2 ohm).

And results are great. The only drawback is, mid speakers cannot keep up with it, though I have changed the rear shelf speakers to L7 aswell.

This is my assumption that you have added hi-fi to your VO and removed L7 code from your VO.
Then you wrote RAD2 to its default parameters through expertmode.

And it worked for you.

I don't know if that was a question but yes that's exactly what I did

bmw325i, in my case I did not had to delete other codes.
Just added 676 in to VO and it worked like a charm.

Does anyone have a postcode for makkan00's workshop. Agreed a time for some coding, but unable to contact him via facebook...
