Custom built fiberglass sub box with 2 JL Audio 10TW3 D4 subs. Dual 4 ohm voice coils. The box was built to fit in the right rear corner with room to still open the load floor. The subs hit hard and sound like new. Includes speaker grills and wired for 2ohm. I’m giving the Nitro to my dad for a while and he doesn’t like the bass at all.
