I have two of these subs in a forward firing un2.5 ft³ under seat box of a crew cab 2015 Silverado. Box is tuned to 35hz. They hit the lows really nice.
I got this woofer in a 4ohm at first but while wiring it up to 2ohm it got slashed so sold it for cheap and ended up with a 2ohm wired to 1ohm . This thing is a complete monster . The video is before break in the first day of install while the suspension was still stiff now this thing flexes like a champ . Def recommend . Obviously have your box build to specs if you want to smack on 15 inch subs . People ask me if I’m on a 15 how funny 😆
Purchased a zvx 8" the sub itself is a beast but skar box specs for it are pretty far off. Built a custom box to spec and it is definitely to big. It does not sound bad but it does sound muddy. Needs about .75 to .90 cf ported.... Not 1.25cf. excited to downsize the box and let it eat on the skv 1500.1
I have 4 of these little beast in a sixth order and it slams. Have not metered yet. Also running on a sk3500. These subs will take beating. Highly recommend these subs.
