CANT WAIT TO HOOK EVERYTHING ELSE UP. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars This box fit well in my 2014 Silverado Crew Cab ... *by R***F on Reviewed in the United States πŸ‡ΊπŸ‡Έ 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. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great product *by L***T on Reviewed in the United States πŸ‡ΊπŸ‡Έ on November 28, 2016* A perfect fit and quality made. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/71354466-subthump-2014-2018-chevy-silverado-gmc-sierra-crew-cab-dual](https://www.desertcart.jp/products/71354466-subthump-2014-2018-chevy-silverado-gmc-sierra-crew-cab-dual) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-18*
