I wanted the 4 10 box for my crew cab but with kids I couldn't justify it. So I conceded and got the dual 8 box. I have 2 Skar EVL-8s with a Skar SKv2-2500.1D at 1 ohm. Wholly Sheet! This box will rattle your eyeballs! Its obnoxious! Im an old school basshead from the 90's and installed professionally in the 2000s. I've had some pretty sick setups over the years. But you will not find a prefab box that sounds like this anywhere. Hell, you'd be hard pressed to get most custom boxes to sound like this. The pic of my dbs was taken with the windows up on the dash with an app on my phone. So not an official score. That's pretty freaking impressive for 2 8s in a truck and only tuned by ear. I have SMD tuners now and will update if possible.
