GUYS double box your items.. anyways not going to send it back, while fixing this POS it is just a stable piece of sawdust. the only thing that holds this thing together is a spray lining. how this became #1 is a joke. get yourself something that will rock your space .... get a SKAR AR1X12V... solid and double boxed.this unit at #1..... right must be a joke ### ⭐⭐⭐⭐⭐ Perfect Box once you seal it! Paired it with a T5-122 Tarantula & a Taramps HD2000.1 *by on Reviewed in the United States 28 November 2025* This box is great, but you MUST seal it yourself. I paired it up with a Tarantula T5-122 sub. This sub recommends tuning at 30ish hz but it QUAKES in my single cab Chevy. I’m pushing it with a Taramps HD2000-1ohm amp. I adjusted to amp to respond between the recommended Hz for the sub and the 54Hz that the box is tuned at. I have my gain and boost at 1/3 max and it’s hard to breathe when I hit max volume on my stereo. Perfect setup for less than $500. I haven’t broken in the sub yet so I’ll update this review later. They say 3/4 mdf but it seems more like 5/8ths, if you don’t seal the box it will rattle and crack the Berliner coating. Overall this thing has impressed me. Worth the $$ and with the right sub it POUNDS. Do the research, the T5-122 was the best sub I found in my price range to fit the tune of this box. ## Frequently Bought Together - Rockville RQ12TB Single 12" Ported Subwoofer Box, BedLined, 2.2 Cu.Ft., Durable MDF, Space-Saving Triangle Design, High-Quality Terminals, for Car Audio Enthusiasts - Rockville Destroyer 12D2 2000W Peak Subwoofer Dual 2-Ohm, Kevlar Cone, Cast Aluminum Basket, High-Excursion Bass, for Car Audio Enthusiasts - Rockville dB16 8000W Mono 2-Ohm Car Amplifier, High-Speed MOSFET, Adjustable 12dB Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/417692059-rockville-rq12tb-single-12-triangle-ported-subwoofer-bedlined-enclosure](https://www.desertcart.gr/products/417692059-rockville-rq12tb-single-12-triangle-ported-subwoofer-bedlined-enclosure) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-29*
