The sub-enclosure is only 2.8 inches thick and easily fits under your seat. Built-in amplifier makes installation and wiring neat and simple. This is a true all-in-one subwoofer solution with a subwoofer built into the enclosure and includes a top-of-line amplifier. We have designed this unit with you in mind. Add a high level of input and can be installed on aftermarket or factory systems. High level input allows installation even when there is no preamp output. Smart turn-on circuitry detects the presence of an audio signal and turns the amplifier on. When the music signal is turned off, the amplifier built into this subwoofer system will automatically turn off. All inputs and outputs are placed on one side for a quick and easy installation. This makes wiring neat and easy. Our competitor models are more difficult to install. The SS8P features 400 watts of peak power and 100 watts of RMS. It has great control so you can adjust the sound according to your preference. Volume and subsonic filter level control filters out really low frequencies that are not heard by human ears. It also features a low-pass crossover filter, phase control, input sensitivity and bass boost. Comes with a remote base knob and mounting hardware, but the best part of our model is sound. Slim but sounds like a full-size subwoofer Description of RWK10: The Rockville RWK10 10 AWG (American Wire Gauge) Amplifier Kit is different from other amplifier kits on the market. 1. Our RCA cables are made of 100% copper. Top of the line RCA cables. 2. Better Resistance: Resistance rating is the only thing that really matters. This is a measurement of conductivity and signal loss per foot of wire. Rockville wires are made by about three times the copper than other wires, so these wires have a much better resistance rating and transmit more power to the amplifier than other brands. 3. Don't be fooled by wire thickness. These are standard American wire gauge thickness. This is another reason why our conductivity is superior to anything else. Other brands on the market write 10 gauge, but the thickness is just about you. We are honest about the thickness Review: Rockville subwoofer Review: Buy it! ## Features - Package Includes: (1) Rockville SS8P 400 Watt Slim Underseat Active Powered Car/Truck Subwoofer Subwoofer Subwoofer Sub, (1) Rockville RWK10 10 Gauge Amp Mounting Kit ANL Fuse Holder 100% Copper RCA - Rockville SS8P 8" 400w Slim Underseat Active Powered Car/Truck Subwoofer Sub The enclosure is made of cast aluminum to keep you cool at all times.

Its complete along with rubber insulation you gave to attach yourself. I would suggest electrical tape, wire strippers, and a pair of terminal/electrical pliers (I apologize if you are already aware.). **Q: Has anyone added a second sub to their system?** A: Yes. I used RCA splitters and installed two in my Mitsubishi Montero. Sounds amazing and have been going strong for 3 years. I tried to split the remote control using a telephone line splitter but got weird feedback when I tried to do that, so I just went without the remote control. **Q: How difficult is this to install?** A: It's easy to install if you understand stereo systems and how to run the wires. The hardest part is getting to your stereo. Not sure if you have experience or not installing systems. If you do, its easy. **Q: If I got splitters for both the rca and remote control (telephone jack), can I install one sub under each of the front seat?** A: Yes. I split my rca signal and installed 2 of the speakers. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Rockville subwoofer *by M***W on April 3, 2025* ### ⭐⭐⭐⭐⭐ Buy it! *by N***E on January 12, 2020* ### ⭐ Hard to get correct settings *by R***N on July 19, 2024* ## Frequently Bought Together - Rockville SS8P 400 Watt Slim Under-Seat Powered Car/Truck Subwoofer Sub+Amp Kit Black - Kicker 46KISLOC2 K-Series Stereo Line-Output Converter w/Remote Turn-On Output - Nilight - 50004R 120 Pcs/60 Pairs Quick Splice Wire Terminals T-Tap Self-stripping with Nylon Fully Insulated Male Quick Disconnects Kit, 2 Years Warranty --- ## 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/728711831-rockville-ss8p-400-watt-slim-under-seat-powered-car-truck](https://www.desertcart.vn/products/728711831-rockville-ss8p-400-watt-slim-under-seat-powered-car-truck) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-15*
