Thread: Logic7 / Meridian Surround Sound Retrofit 2012-2016 D4

About how much?

That D panel looks like a different moulding to standard. Are they readily available?

It depends on if you go for new or used parts, if you do the install yourself, etc...

The wiring harness is $220 + postage
The amp you could pay anywhere from $150 to $750 2nd hand (forget new, talking thousands)
The rear pillars with speakers new are about $550 a pair, used ones hopefully cheaper if you can find them.
The centre speaker on it's own anywhere from $50 to $125 depending on new or used.
Takes me about 3hrs to make the installation, other people may need more time.

It's a factory part, but yes the d-pillar trim panel is different between the standard or surround system, also different between 5-seater or 7-seater.

I have a pair of 7-seat ones here on my shelf, brand new still in plastic, with the speakers. And a centre speaker as well.

My 2014 D4 is not surround but it's b loud. Can't imagine what one with near double the output power is like 🤤

It already has a centre speaker in the dash so I presume you are replacing this with a dual cone?

Also has DAB which is useless cept in the city.

It's awesome really. Not just double the power but the extra speakers make the sound so full.

All the cars were built with the centre speaker grille, but you'll find that there's no speaker in under there, it's empty.

DAB is good when you can receive it, but yeah it's only in the capitals.

If your 2012-2016 D4 has the 11-speaker "HI-ICE" sound system, i.e the Harman Kardon system in 2012-2013 models, or the Meridian 380W system in the 2014-2016 models, it's relatively straight forward to upgrade to the 17-speaker surround system; Harman Kardon Logic7 or Meridian Surround 825W.

Hi Cambo, really interesting to see your retrofitting. Dreaming of doing the same. I have today a Discovery 4 2014 with the meridian "high-line" and want to upgrade to the 825W system.
For a Meridian system is it still possible to use the logic 7 amplifier or do I need one rated to my -14 Meridian system? Dont know if the "intelligence" is within the amplifier or the cars internal system.

On the amplifier it says 12(from other treads, have not looked myself) and I can only count to 11 speakers(3 in each front door + 2 in back doors + sub) in my car, would it be possible to only add the center in the dashboard and connect to the already existing amplifier?

Always a fun work to modify cars. Happy to see more of your work

Hi,

The 380W Meridian has the "High-12" amp same as the Harman Kardon in the earlier models.

The 825W Meridian Surround needs a "Prem-16" amp which is a different amplifier to the Logic7 in the earlier cars, you can't run a Logic7 amp in a Meridian car & vice-versa.

The "High-12" amp cannot give you a centre speaker channel.

If you're counting speakers, the subwoofer actually is a dual-voice-coil and there are two channels from the amp to the sub.

thank you for your quick feedback
Are there any problems to mount the connectors to the center speaker. Im afraid that I need to remove the full dash before Im done :P
