I have 2 FI SSD 10's that are down firing in a box under the rear seat of my truck. The box is approx .48 per woofer after displacement. The subs are fully loaded with the sealed high QTS option.
FI states these subs work in a .2-.4 cube box with the high QTS option.
My question is will I see any benefit to adding polyfil to my box?
Thank you for your time
