With a peak power handling of 400 Watts and RMS power of 100 Watts, this subwoofer delivers deep, rich bass while maintaining a compact design. It features advanced protection circuits, adjustable input sensitivity, and comes with a complete installation kit, making it the perfect addition to any vehicle audio system. ## Description Description of SS8P: The SS8P is an all in one solution to give you great sounding bass in your vehicle without taking up a lot of space. This sub enclosure is only 2.8" thick so that it can easily fit under your seat. The amplifier is built in, so installation and wiring is clean and simple. This is a true all in one subwoofer solution with the subwoofer built into the enclosure along with a top of the line amplifier built in as well. We focused on making installation a breeze so we designed this unit with you the customer in mind. We added high level inputs so you can install this to an aftermarket or factory system. The high level input allows you to install this even if you have no preamp outputs available. The smart turn-on circuit will sense that an audio signal is present and turn on the amplifier. When you turn off your music signal the amplifier built into this subwoofer system will automatically turn itself off. Something else we did to make installation quick and easy is we put all the inputs and outputs on one side. This makes wiring neater and easier. Our competitor's models are more challenging to install. The SS8P has 400 watts of peak power and 100 watts RMS. This has great controls so you can adjust the sound to your liking. It has a level control for the volume and subsonic filter to filter out the really low frequencies which the human ear cannot hear. This also has a low pass crossover filter, phase control, input sensitivity, and bass boost. Included is a remote bass knob, and mounting hardware but the best thing about our model is the sound. It is slim but it sounds like a full sized subwoofer If you are not happy with it we will offer you a 90-day money back guarantee. If you don't like the sound, we will send you a pre-paid label and refund you in full! Description of RWK10: The Rockville RWK10 10 AWG (American Wire Gauge) amp kit has the following differences over other amp kits on the market at this price point. 1. Our RCA cables are 100 % copper. These are top of the line RCA cables 2. Better Resistance: The only thing that really matters with wires is the resistance rating. This is a measurement of conductivity and how much signal is loss per foot of wire. Since Rockville wires are made with around 3 times as much copper as any other wire at this price point, these wires had a much better resistance rating which means they will transfer more power to your amps than the other brands. 3. We do not cheat you on the thickness of the wire. These are standard American wire gauge thickness. This is another reason our conductivity is better than anything else at this price point. Other brands in the market place write 10 gauge, but cheat you on the thickness. We are honest about the thickness.

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 3 April 2025* ### ⭐⭐⭐⭐⭐ Buy it! *by N***E on 12 January 2020* ### ⭐ Hard to get correct settings *by R***N on 19 July 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.vu/products/588618775-rockville-ss8p-400-watt-slim-under-seat-powered-car-truck](https://www.desertcart.vu/products/588618775-rockville-ss8p-400-watt-slim-under-seat-powered-car-truck) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
