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
