    They Bang

    Posted by Brent Ecton on Mar 27th 2021

    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!

    Wow

    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...

    Beast of a speaker

    Posted by Brian DeBoer on Dec 13th 2019

    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
