Bangin Little Box

Don’t let the size of these two 8s make you shy away from them, they are bangin! A had a single 12 in my trunk but wanted a cleaner sound with plenty of bass and this box is able to just that.

I had the VD-12 until I caved and bought these. Much more crisp and loud bass from these tiny little things! You absolutely can't beat the value of Skar... Very high quality and fast shipping.
