*by R***F on Reviewed in the United States 🇺🇸 on April 22, 2016*

This box fit well in my 2014 Silverado Crew Cab. Decent spacing for an amplifier which I used to place a JL 500/1D amp, a Planet Audio 2 farad cap and 2 distribution blocks. Mounted two JL 10w0v3 into it. Came well protected in the packaging, so the item had no damage. Has a smell, so minus a star. all-in-all a quality item and worth it.
