I have the Hi-Fi speaker upgrade and wanted to finish it off with a sub. I tapped into the existing Harmon Kardon amp and got my amp wiring (Jig is doing a How To on this). But I needed a good sub enclosure to complete the job. This is where x555 and his skills came into this!
I went with my original Infinity Kappa 10†you see in the pictures but that was not perfect for this enclosure. We get a capacity of 10 litres which is ideal for the Focal Polyglass 21V2 8†– credit to Pewters and Jig for finding this.

An expensive sub for only 8†dimensions but this thing is brilliant, true testament to x555s craftmenship!

So here’s some pics of his handy work and what it looks like in my car:






Finally the new sub:
