R1S412 FeaturesSpeaker Construction 12 AWG compression terminals Parabolic polypropylene cone Single voice coil design Stamped steel basket 18 gauge stamped steel frame. Optimized for sealed enclosures Aluminum V/C Former Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide excellent heat dissipation. Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions. CEA-2031 Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. This means your speaker has the capacity to handle power under continuous damand, not instantaneous power handling, that over time, can damage voice coils.

The subs dont hit super hard, however I feel that the bass is perfectly boosted now with my system in my truck. On songs with no bass, its not over powering. Songs that have heavy bass, the subs come to life and improve the music greatly. Some people think that they are too weak and are a waste of money, that is until you tell them how much it cost. With the amp, box, and two subs, you can have a great starting set up for under 200$. I think they are worth the money for that if you listen to other music than just stuff that is very bass heavy. ### ⭐⭐⭐⭐⭐ Perfect for home theater upgrades! *by A***R on July 20, 2017* I needed a speaker to upgrade my home theater system. We have an LG Bh6820s-w 1000 watt surround sound blue ray player. It puts out 126w @ 3 Ohms to the 6.5" subwoofer it came with. After searching several weeks for something to enhance the quality of sound (deeper more powerful bass) I arrived at this speaker. (I added it into several modeling programs) The R1S412 that I purchased did not leave me wanting! You can literally feel the explosions! I converted one entire side of our entertainment center into the speaker box. I have a net total of 5.13 cubic feet of internal volume, roughly 90w @ 4 Ohms, and the box is tuned to 18hz with a 15" section of 4" pvc. I stuffed some 1" foam seat cushion into the port to decrease the booming in the lowest of lows it reaches. Could not be happier with the intensity this thing brings to our home movie nights! I've gotten as low as 25hz at 85db. Now that's impressive for a 12" speaker on 90w! ### ⭐⭐⭐⭐ Hitting the Mark *by M***0 on August 27, 2013* Nice single addition for my 2001 Siverado. Won't blow the doors off but fills the cabin pretty fine. Good choice if you want to add more low end. ## Frequently Bought Together - Rockford Fosgate R1-S412 400W Wired Subwoofer - Black - BOSS AUDIO RCA KIT2 8 Gauge Installation Wiring Kit For Amplifier, Multicolor - Rockford Fosgate Prime R1T-S 80 Watt Tweeter Kit (Multicolor) --- ## 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.vn/products/5069308-rockford-fosgate-prime-r1s412-r1-12-inch-150-watt-subwoofer](https://www.desertcart.vn/products/5069308-rockford-fosgate-prime-r1s412-r1-12-inch-150-watt-subwoofer) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-09*
