Hi,

Any idea where I can route power cable for additional amplifier from battery to trunk. I would like to upgrade my subwoofer and possibly front door speakers in future.

I ran my power cable (for my air ride) under the car and in the trunk through a grommet

Not my first thought to run power cable under car.

Why not.....its how Audi do it when the battery's are fitted in the trunk to get power to the front of the car.

There are plenty wires that are under the car for various applications, not to mention the brake lines, fuel lines etc.

Run it along the same path the brake lines run. All protected under the plastic undertrays.

Dumb question alert 🤣

Is the sub in the boot already not a powered one ?

OK, I rest my case here

Yes it is but the caballing is insufficient to power an aftermarket amplifier to then run an aftermarket sub.

Does anybody have Bang & Olufsen stereo and can tell me is there separate volume adjust setting for subwoofer. My Audi Sound System does not have that, only bass and treble. Let me know if you can check this.

With my B&O stereo, main menu screen > Sound and then the following screen is displayed with level controls including Subwoofer.

I also have the Audi sound system with the subwoofer and have no controls. I read somewhere that it is a bug and can be activated with VCDS but as I don't have it then I cannot confirm this.

 

[HiTec]

OK, that's good news if it really can be activated. It would be nice know where it can be coded because I have vcds cable. Maby I spent a night in car to figure it out

It's done. I routed powercable through clutch bushing and mounted amp under the driver seat. 6,5" subwoofer in trunk and still 2 channels to go if I like to upgrade front door speakers.

Can you share more details of your subwoofer box. I'm interested on making one.

I just stacked plywood on top of each other. Start from bottom and cut as big piece as possible. Then just stack another one and you are done. Then cut inner part out and be carefully not to cut too much. Maybe these pictures help
