Audi A6 C7 2016 Amplifier and Sub Install

[a_naqui]

Hi,

I have a 2016 BE with the Bose system and like most, I was a bit disappointed with the bass. I already had a sub and other equipment from my last car ( Focus Zetec S 182 - My Car, pics and 220BHP - Ford Focus Forum, Ford Focus ST Forum, Ford Focus RS Forum), so started looking into how and where to install a sub.

However, all the pictures on the web showed a different amp mount to the one in my car.

In the end, I decided to use some perspex (white was all they had and i'm impatient!) and came up with a mount as shown in the pics below:-

Original bracket with the amp removed. Note the 3 slots in the middle - this is where the TV tuner bracket slots into. There were 3 empty holes that I used to secure the perspex sheet to.




I then mounted a new amp I picked up. It matched the sub, and its size meant it was a good fit for the bracket:-





Mounted my LC2i above:-






After bit of cable routing etc, the amp and LC2i were all connected up:-




I tapped into the subwoofer signal using micro spade connectors as I didnt want to splice into the loom just yet:-



Adjusting the LC2i and amp:-



Bose amp back on:-



And mounted back in place:-




I tapped into the un-used fuse for the TV tuner for my remote turn on. I tried using GTO on the LC2i but found it unreliable.
However, I am finding that the amp cuts out and back in when the Stop\Start is starting the engine back up. Has anyone else had this?

I need to adjust the settings a bit more, but overall a vast improvement over the Bose sub!

Top job buddy!
I have just gone through a similar process and used the sub high level output through one of these-

What is your LC2i? Is it doing the same job (but with more features)?

I used a spare ignition switched fuse position on the other side of the boot and I do occasionally have the cutout issue you described.

Cheers!

the LC2i has a few extra features such as overcoming factory bass cut off, and two channel RCA output. Bass cut off doesnt seem to be an issue with the Audi system - but I had the LC2i from my Focus which did have bass cut off issues.

My other option would have been to use the high level input on the amp, but the LC2i gets rave reviews.

Glad to know i'm not the only one getting the amp cutting out on stop\start. I might have a play with where I am connecting to the battery from.

What JL amp and sub did you get?

Tidy job that pal... Nice one!

[Alex jb]

When I'm testing or enjoying and traffic is likely I just turn off the stop/start

Not likely to win any SPL comps, but with a flat tune of port to about 35hz it clean and up to around 122dB on music.

Nice!

I'm using the following amp JL Audio JX500/1D -

and a JL Audio 12" basswedge

JL-Audio-CP112-W0v3-12-12W0v3-Slot-Ported-BassWedge-_1.jpg

It's very well built and delivers great bass.

I've got a couple of small changes to the car - once the we get a clear day, I'll put some pics up after a wash

[Alex jb]

Nice kit.
Are you loading the sub against the back of the seat or firing into the boot?
Makes quite a bit of extra dB loading against a near by surface, but I am still changing boxes to find the best compromise.
With my 60% seat down and same settings I went up from 122 to 124

I can see your car is saloon as mine. Do you get any parcel shelf vibration issues ?

[Alex jb]

Sure do, the trim is coming off over the break and 2 sheets of roadkill are going in.
(Along with the new 12ga speaker wire)
