Upgrading MK7/MK7.5 Golf R Fender Subwoofer without amp

The Fender subwoofer that came with the car while functional, was not enough for me. I wanted more base while not having to run power wire and use line converters. I wanted something that was plug and play and still have a fully usable trunk. After searching around the web, I copied an approach from www golfmk7.com/forums/index.php?threads/fender-subwoofer-cheap-and-easy-review.351549/. Here are the parts you'll need: R2SD2-12 - Sub Rockford Fosgate 12" Prime R2 2-Ohm DVC Shallow Subwoofer (must be dual 2-ohm voice coils) 8E0-972-714 - Plug to plug into factory subwoofer harness 000-979-226-EA - Two of these for the plug AK Audio Box - ak-audio.com/collections/volkswagen/products/2012-2016-volkswagon-golf-vw-subwoofer-box-enclosure-car-speaker-10-12-subs 16/14 gauge speaker wire 16/14 female quick disconnect connectors Blacktape
