2007+ GM CREW CAB 4-8" VENTED

Best speaker Box I have had

Amazing

Switched my same speakers from a prefab amazon box and night and day difference

This box is amazing!!

I like this box, I have 4 Skar ZVXV2 8 inch subwoofers I put in this box which sound great and hit good, using a Skar RP4500.1D amp wired to 2 ohms. I called Fox Acoustics Customer Support and they were extremely helpful, they were sadly unable to tell me if that box would be a perfect fit for those subwoofers but tried to help me as much as I can. The shipping was fast and box came undamaged. The only downside is that the durable coating applied to the box interfered with the subwoofers sizing only on the inner ring of the subwoofer hole. This resulted in me sanding down just the coating until it got to the bare wood. Once I did that, the subwoofers fit perfectly and even though the specified airspace on the box is smaller than what the subwoofer is rated for, the box still does a great job and the subwoofers hit hard as well as the box fitting great in the truck. I would recommend this box to anyone with the same truck as it was an amazing experience.
