I modified my rear seat to let bass through, since I will be using a forward-firing sub stage that is sealed off from the rest of the trunk. This is due to the extensive treatments I’ve already done in the rear. The rear seat has a hard wooden backing that needs to go, and since no one sits behind my seat, that foam section needed to be removed.
Start by opening up the cover and removing it.
The latching mechanism needs to remain, so we have to leave the center.
Cutting the foam out was easy with a long bladed knife. Just avoid cutting through metal and I retained the Velcro strip so the seat would look good.
Completed
This was a test, the final configuration will be custom to fully seal to the opening.
Can’t tell anything is different.
