2021 Bronco Sport Speaker Upgrade With amp and SubWoofer

Here is a follow up video on the Bronco Sport speaker upgrade I did a couple months back. I added a five channel Kenwood amplifier and a 8" ported sub woofer. The Amp gave the speaker more volume, but not much punch. So I decided to add the sub woofer to fill in the missing bass. I did not want the sub to take up any storage space or be out in the open. The design I came up with was to fabricate a sub box with storage that fits under the rear cargo floor.
