My custom sub enclosure

B7 A4
#1

Hello everyone.
Here is something I have been working on for some time now.
A custom box fitted for the b7 that fits in place of the storage compartment located in the trunk on the drivers side.
Take a look.
Test fitted the box:

For reference how I have the box secured:
Using these from left to right to mount the box from moving. You can use whatever size you desire.

I cut this one. It was 2".

Here is where the bolt is going. As you see, that’s the hole I drilled to fit the bolt.

Thanks for looking.

That is good work. It looks like you used bondo on the outside was the box that you started with fiberglass.

#3

Correct you are sir. That was my first gen enclosure.
I have now moved on from that and have a new mold made.

This one here is for sale now as I won’t be building this model anymore.

There was a company that used to make these but I can’t remember the name off hand. It was a nice product, made out of marine grade fiberglass. I had them build one slightly more robust for me as I used it for a 10" W7. Great spot for a subwoofer though.

#5

I had bought one off one of those sites as well. It was well made, so I decided to go my route and adventure out for one on the driver’s side of the trunk. Theirs was for the pass side. I didn’t like it at all the way it stuck out in the trunk.

Thanks.

This is what it looks like completely installed with a 10" sub. For those that like their trunk space like I do. This will be one of the routes to go.
