I’ve been running (1) x8v3 for 4 years now and always wanted another. Very impressed with this sub from day 1, the 2nd was the icing on the cake

Amazing subs! Everyone says I’m lying those aren’t 8’s!! Then I show them and they still don’t believe me! Down for sound and Sundown for the WIN!!

I ordered a pair of the sundown 8” xv3 my first order was sent to the wrong person, I mailed the wrong speakers back. In a week, I had the correct order. They were packaged nice, Ill be getting 2 more before install. Thanks D4S

I’ve had a ton of Class B subs probably even class C setups in my vehicles over the years. This was an attempt at getting into a higher class. And boy was Johnathan right on these. I researched for months on end trying to find a sub that would fit behind my crew max seat, without going shallow mount. These subs are absolutely spectacular. I can see why sundown has the reputation they have. These subs are worth every penny, and I couldn’t pass on almost 50% off when I purchased them. Absolutely fantastic. Just wish I could fit more. Now that I have the alternator to run more. I want more. But that’s not because these aren’t loud enough. Just hooked me into wanting more

This one is almost up there with the dd2508sw,I fried one of these in a 1cuft box,just didn't peak how i wanted so purchased 2 more of these because of that There in shared 1.5cuft now box and slapping off a,xtr2500.1dz witch is overkill.If your shopping for an 8 and they haven't came out with a fourth revision,I recommend this one!

The subs hits hard and man do they ship fast !

I got 2 of these for my 2014 double cab gmc sierra on a DD M1d with the mechman 320 amp alternator and 2 batteries. Holy shit they bang! I never would have thought a pair of 8s would hit like this so I'm beyond impressed! Wish I could fit 2 more...

These things hit hard people don’t expect them to be 8’s slam like 12’s. JP and his team will take great care of you as well.

The X8's are a beast! The magnets are almost bigger than the woofer. I'm very impressed!! Thanks Down4Sound team!

Gets nice and low like you’d expect from a X series, what surprised me was the quality and musicality of it in the upper range of bass, it’s not just a bottom end monster, unbelievable quality sub
