I did the damping of the box and there was room for it. I also did damping from the backseat to the rear plus the tailgate. I did the inner fenders and wheel arches. Still on stock speakers and have not damped the doors and floor. I like to get the new Helix Compose speakers but it will have to wait for now.

Then I would use the PP-MQS. That is plug n play. I used the other one but made the speaker connections my self.

I installed the amplifier next to the glove box on the right side as there is plenty of room for it there plus wiring harness. I have pulled a 6mm2 cable from the battery and there is a solid point right next to it close to the right front door where a 6mm2 cable is also attached. I researched several ways to connect the amplifier to the factory radio and ended up using the supplied wiring harness for the amplifier. Then I put on the iso speaker plug myself and bought a Match PP-ISO 1 Plug & Play ISO cable to plug it into the car wiring harness. Looked at Match PP-MQS 1.4 Plug & Play harness and the Match PP-PAC92B harness which ones are both plug and play versions but I found that when you want the amplifier in high power mode, it is easiest not to use them. And I bought both 🙈 The cable for the subwoofer was made with the help of a colleague who is super good at the small molex connectors. I tried myself but it didn't work, something easier with the slightly larger iso plugs.

Yes I use an adapter from Ottocast the U2 AIR Pro.

I mostly used 3 layers of damping. First layer is vibration damping butyl 2.3mm, second layers are sound insulation 6mm or 4mm in places where space is tight and third layer are noise absorbing 5mm or 10mm. There are places where I only used 2 layers, under the back seat i used 4mm insulation on top,of the butyl. On the trunk floor i used Mass Loaded Vinyl as the tird layer.

I have been inspired by the great reads on here to do some audio upgrades on my facelift combi from 2019. It have the Asmussen navi with Carplay from factory so just added a wireless adapter. I wanted an upgrade that was small but still with a great sound so decided on a Match M5.4DSP amp installed in high power mode and a 10” sub in the familiar Basser subbox that goes in the left side of the trunk. I looked at various subs to go in the box and I decided to with the JL 10W1v3-2 as it fit the box volume and suits the amp well. The first think to start with was sound damping. I looked alot on Ahifi and how they do. Plus their description is super good, just needs to be translated😊 More pics to come.

480T is the newest version

Looks nice. Got the same sub box from Basser. How much space is there around the box when fitted? I like to damp the box on the outside but not sure if it can fit with 4 mm damping on the back, buttom and top. Thanks

Hi very nice job. I am going down this route to. Got a Match 5.4 and a JL Audio sub going in a Basser box in my combi. Just want to know how much space there is around the Basser box? Thinking about damping the box on the outside but is there room for that?

My 2019 1.5tsi has the under bonnet cover and the rear dust cover fitted from new.

I used this tip of YouTube and cleared it.

So I can confirm that it works using a Mac. I used the tip from freelunch and got the CleanMyDrive2 app.

Mac works great for the navi card Update. So it may work.
