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.

Our RCA cables are 100 % copper. These are top of the line RCA cables 3. We do not cheat you on the thickness of the wire. These are standard American wire gauge thickness. Other brands in the market place write 10 gauge, but cheat you on the thickness. We are honest about the thickness. 4. The Rockville amplifier installation kits feature a new soft abrasion proof insulating jacket. This rugged PVC outer jacket allows for 100% improved flexibility over standard power cables making them extremely easy to route through your vehicles interior, and it maintains exceptional resistance to grease and oil. The PVC outer jacket can with-stand an extreme temperature range of -40 to 220 degrees F. The RCA signal transfer cables included in this kit feature blue and silver twisted pair technology in a clear outer jacket insulation skin. Not only do the blue and silver wires look cool but they also provide superior signal transfer with maximum noise suppression. They are 100% copper to provide absolute lossless perfect signal transfer to your receiver. This technology reduces interference, so your audio signal flows clean and pure at all power levels. The included 7 split loom tube provides protection for your power cable from the typically harsh environment found under the hood of your car. One other last thing worth noting about our kit compared to others. Our kit cosmetically looks the best. It has blue power wire, clear ground wire, and twisted pair RCAs with matching colors. This model includes (1) set of RCA cables.

Most everything is already covered in other reviews but I wanted to give some thanks to Rockville for this design! In another life I loved having worked on cars, having 2x12s in the trunk, nothing was left stock. I consider myself an audio and car enthusiast, but not a pro by any means. I like car modifications to fit as close to OEM as possible. I also like to have audio equipment sound true, flat / accurate with its reproduction. This enclosure is for specifically under-seat applications. You will not be happy with it in the trunk. - Build quality is top notch - solid metal enclosure will break your toe if you’re not careful. No rattles or cheap-feeling at all. All connections and adjustments are on one side, good idea. - Small size will fit *most* under-seat locations. Note: 2015 Hyundai Sonata 2.0 drivers seat has a plastic tray that will hold it, but it is tight. Does not fit ‘on the floor’ under the seat due to a/c duct and gear motor. So the enclosure sticks forward just an inch from the front of the seat towards your legs, but does not interfere or touch. In the seats lowest position it will squish the enclosure, but send vibrations straight to your tushie for an amazing concert-like experience. -10ga Amp Kit was perfect. Quality cables and wires included. You will need a few extra zip ties of your own. I used the ‘soft auto on’ and hi-input connections so I only needed four wires: power, ground, left and right. -Subwoofer gain level remote knob is helpful to route to the dash so you don’t have to keep adjusting the gain on the subwoofer itself. -Power is more than adequate for under-seat locations. Note: Sub is far too quiet when located in the trunk, but it is not designed for that. I tried it in the trunk but needed to move it back to under the seat. -Sound quality is very impressive for a tiny 8” enclosure. You cannot even tell a sub is installed from outside the car (you won’t p*ss off your neighbors). On stock head unit (4x door speakers, 2x tweeters in the dash. Bass +3, mid +2, High +3) Subwoofer bass boost on zero, LPF at ~60hz, gain at 60% the lows are thick and rich, kick drums hit hard. Rock, metal, country - sounds great. Hip hop or techno is average, to above average, because of the ultra low kick and sub hits... there are just a few frequencies that are missing but that could be due to my car head unit eq. Overall, great product! With new JVC CS-J620 door speakers and this sub, my anemic stock car stereo has become fantastic! Review: Great little sub! - This little sub sounds absolutely fantastic for the size and low price. I couldn't be more pleased with it! I installed it in an '88 Toyota pickup Xtra Cab that had an existing low-end JVC head unit running four equally cheap speakers. The setup sounded as you'd expect... not great, even with the built-in13-band eq tweaked as good as I could get it. Bass response was lousy. One huge issue with the setup was a horrible ~150 Hz resonance in the cavities in the back of the cab where the rear 6.5" speakers were installed. I cut that frequency in the eq, which helped tremendously, but the problem remained. I thought about installing some baffles and acoustic mat in there, but figured I'd get the sub in first and see if I could fix it with proper crossover settings. One benefit of small subs is that they can reproduce higher frequencies than larger subs. So I was hopeful I could crank up the sub's LPF and let it handle that troublesome 150 Hz, and set the HPF on the rear speakers above it. I'd planned to install the sub under one of the seats, but protrusions in the floorboard on both sides prevented that. I ended up installing it on the floor behind the driver's seat, close to the back wall of the cab. Wiring was straightforward. I removed the seats to make things easier, and allow me to lift the carpet in order to run the cable for the remote to the center console. I ran the wiring and connected it to the sub outputs on the head unit. It powered right up with the head unit and started thumping with the music! After adjusting the crossovers and eq on the head unit, and tweaking the adjustments on the sub, the system sounded absolutely amazing. I ended up turning the LPF on the sub to its maximum setting, and set the HPF on the rear speakers equally high. The annoying resonance was completely eliminated! I tested the system with several different types of music, including hard rock with tight kick drums, and rap with super-low bass lines, and was just thrilled across the board with the performance of this little, unobtrusive sub. 10/10, would buy again! In fact, I'm about to take some measurements on my '86 Buick Grand National, and if it will fit under the seat, I'm gonna grab another one! ## Features - Package Includes: (1) Rockville SS8P 400-Watt Slim Under-Seat Active Powered Car/Truck Subwoofer Sub, (1) Rockville RWK10 10 Gauge Amp Installation Kit ANL Fuse Holder 100% Copper RCA - Compact Power with Deep Bass: 400W peak / 100W RMS output in a slim 2.8" enclosure for powerful, clear bass that fits easily under car or truck seats. - Advanced Controls: Adjustable low-pass filter (50Hz–150Hz), phase switch (0°/180°), subsonic filter (20Hz), and bass boost (0–12dB @45Hz) for fine-tuned sound performance. - High-Quality Design: Cast aluminum enclosure stays cool; 4Ω impedance, frequency response 20–150Hz, SNR >90dB, sensitivity 90dB @1W/1m; single 15A fuse for dependable power. - Premium Wiring Kit: RWK10 includes 100% copper RCA cables and 10-gauge SuperFlex power wire with low resistance for efficient current flow and clean, distortion-free audio. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079PSSD6N | | Additional Features | Protection | | Antenna Location | Car | | Audio Driver Size | 8 Inches | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Mono | | Best Sellers Rank | #36,131 in Electronics ( See Top 100 in Electronics ) #21 in Car Enclosed Subwoofer Systems | | Brand | Rockville | | Built-In Media | Rockville RWK10 10 Gauge Amp Installation Kit ANL Fuse Holder 100% Copper RCA, Rockville SS8P 400 Watt Slim Under-Seat Active Powered Subwoofer Sub | | Color | Black | | Compatible Devices | Smartphone, Tablet, MP3 Player, Desktop, Television, Projector, Laptop | | Compatible with Vehicle Type | Car, Truck | | Connectivity Protocol | RCA | | Connectivity Technology | RCA | | Control Method | Remote | | Controller Type | Remote Control | | Customer Reviews | 4.4 out of 5 stars 1,546 Reviews | | Enclosure Material | Aluminum | | Frequency Response | 20 Hz | | Impedance | 2 Ohms | | Input Voltage | 12 Volts | | Is Waterproof | FALSE | | Item Dimensions D x W x H | 11"D x 14.1"W x 5.4"H | | Item Weight | 11 Pounds | | MP3 player | No | | Manufacturer | Rockville | | Model Name | SS8P | | Model Number | SS8P+RWK10 | | Mounting Type | Under-Seat Mount | | Number Of Circuits | 1 | | Number of Audio Channels | 2.0 | | Number of Items | 1 | | Power Source | 12-volt DC electrical system | | Processor Count | 1 | | Signal-to-Noise Ratio | 90 dB | | Speaker Maximum Output Power | 400 Watts | | Speaker Size | 8 Inches | | Speaker Type | Subwoofer | | Specific Uses For Product | DJ | | Subwoofer Connectivity Technology | Wired | | Subwoofer Diameter | 8 Inches | | Unit Count | 1 Count | | Warranty Description | 1 Year Manufacturer | | Warranty Type | Limited | | Wireless Technology | No Wireless Communication Technology | | Woofer Diameter | 8 Inches | ## Product Details - **Audio Output Mode:** Mono - **Brand:** Rockville - **Connectivity Technology:** RCA - **Frequency Response:** 20 Hz - **Speaker Maximum Output Power:** 400 Watts ## Images ![SS8P Bundle: 400-Watt 8 in Slim Under-Seat Active Powered Car/Truck Subwoofer, RWK10 10 Gauge Amp Installation Kit with ANL Fuse Holder and 100% Copper RCA Cable, 2-Items - Image 1](https://m.media-amazon.com/images/I/71ErSDiXvZL.jpg) ![SS8P Bundle: 400-Watt 8 in Slim Under-Seat Active Powered Car/Truck Subwoofer, RWK10 10 Gauge Amp Installation Kit with ANL Fuse Holder and 100% Copper RCA Cable, 2-Items - Image 2](https://m.media-amazon.com/images/I/710QlUy+RzL.jpg) ![SS8P Bundle: 400-Watt 8 in Slim Under-Seat Active Powered Car/Truck Subwoofer, RWK10 10 Gauge Amp Installation Kit with ANL Fuse Holder and 100% Copper RCA Cable, 2-Items - Image 3](https://m.media-amazon.com/images/I/817GqrBIz6L.jpg) ![SS8P Bundle: 400-Watt 8 in Slim Under-Seat Active Powered Car/Truck Subwoofer, RWK10 10 Gauge Amp Installation Kit with ANL Fuse Holder and 100% Copper RCA Cable, 2-Items - Image 4](https://m.media-amazon.com/images/I/816XXEJZN8L.jpg) ![SS8P Bundle: 400-Watt 8 in Slim Under-Seat Active Powered Car/Truck Subwoofer, RWK10 10 Gauge Amp Installation Kit with ANL Fuse Holder and 100% Copper RCA Cable, 2-Items - Image 5](https://m.media-amazon.com/images/I/71cSqa9U0XL.jpg) ## Questions & Answers **Q: is everything in the box needed for Installation?** A: Yes, with the accompanying Amp Kit. 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 ### ⭐⭐⭐⭐⭐ Buy it! *by N***E on January 12, 2020* Another cliche ‘I don’t write reviews’ post here... but I am very impressed with all aspects of this subwoofer!

However I only received the speaker. A few days later, I got the wiring kit separate. Installed the speaker the day I got it after a quick run to get a wiring kit. Kinda sucked but nothing too crazy. Upon first inspection, the speaker felt robust in build quality and dense. Really felt like a quality product. I installed this onto my 2015 smart car fortwo with the base two speaker system. The two speakers had sounded horrible and broke so I put in some aftermarket pioneer 6.5" full range speakers and they sounded much more full and clear. However, the bass was lacking incredibly. In addition, the smart car has tons of engine bass and vibrations that any bass I could hear while stationary with the door speakers got drowned out with road noise and such. So I decided to get this small compact sub to slide behind the drivers seat. It fit perfectly. After installing and some tuning, this thing sounds amazing for the small size. Sure it won't blow you away of shake mirrors too much, but it is exponentially better than what door speakers and produce. I must say however, that it isn't all perfect. Some things I noticed was that the bass knob that comes with it is basically useless at high volume. And that brings me to my other point, this sub no longer increases in power after a certain volume. Assuming I've got the gain up high and the bass knob at like halfway, once I turn up my headunit over 22 volume, the door speakers begin to get louder than the bass. My door speakers begin to distort at around 26 volume so basically there's a sweet spot for this sub. Also, keep this thing well ventilated. I've got a small car with the engine right behind me and a relatively weak ac system. Pair that with 100 degree days and some music and this thing WILL get hot. I've got it behind my seat in an area where ventilation is pretty bad so I understand, but its gone into protection mode two or three times already. Though it's only done that when I've idled for like 20 mins listening to music. If this is under a seat beside an air vent you'll have no shutting-off issues like I did. I guess it's a pretty great package for like 110 dollars. If your car has no low end, this will most definitely be an improvement. Think of this as a slightly better premium factory bose system level of bass in a car. It's there for sure, but its not two 12". Perfect for me though. ## 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.uy/products/57118801-ss8p-bundle-400-watt-8-in-slim-under-seat-active](https://www.desertcart.uy/products/57118801-ss8p-bundle-400-watt-8-in-slim-under-seat-active) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-06-06*
