Rockville SS8P 400 Watt Slim Under-Seat Powered Car/Truck Subwoofer Sub+Amp Kit

AMAZING SOUDND quality for a reasonable price. Rockville's customer service representatives are passionate and professional. Thanks for the quick support and a great product.

Another cliche ‘I don’t write reviews’ post here... but I am very impressed with all aspects of this subwoofer! 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!

U set it up u get flat spots u reset it still just dosent quite get there. It took 3 weeks to receive it as it seems the courier service lost it for 2 weeks. Over all my experience with product was disappointing

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!

I've only had the Rockville SS8P installed in my Jeep TJ for a few days, but I'm very pleased thus far! As most Jeep Wrangler owners know, cabin space is at a premium, so I wanted something that would add just a little bass and low end sound to my aftermarket system w/o compromising my limited storage space. I recently purchased a Kenwood Excelon KDC-X304 head unit (which I love) to power 2-Pioneer 6.5" speakers in the roll bar, and 2-Pioneer tweeters in the front dash area. As TJ owners also know, the stock stereo system configuration offers very little low end sound and the result is a very treble-heavy, "tinny" sound field regardless of the quality of the components installed. I originally purchased a Kenwood SW11 compact powered subwoofer that was DOA, so after returning that device (no knock on Kenwood -- just a random bad unit), I decided to give the Rockville SS8P a shot after reading many positive reviews. I'm pretty particular about the sound of my music, so I was a bit skeptical of how effective the SS8P would actually perform. However, after getting a little tuning advice from a friend who is sound system savvy, I installed the SS8P using the RCA cable option (which was very simple -- hardest part IMO was simply routing and hiding the cables). My order also included the Rockville RWK10 amp install kit (also impressive in its quality -- I highly recommend) which made the install process much easier. After tuning the gain w/ a 60Hz test signal, and setting up the signal crossovers in the head unit to direct sound signals appropriately, this little beast has exceeded my expectations thus far! If your space is limited and you are looking for something to "fill in" the lows and create a balanced sound field, the Rockville SS8P might be what you're searching for, especially if your musical tastes are in genres that are not overly "bass-heavy" (ie: rock, country, etc.). In addition, the sound quality is crisp and clear (thus far) with minimal distortion unless the unit is pushed to max volume and/or bass levels. As most reviewers have expressed, the Rockville SS8P is certainly not going to rattle the neighbor's windows, but it does produce a consistent "rumble" that I can feel in my driver seat despite the woofer being installed under the rear passenger bench seat. Even my 14-year-old daughter (who listens to a lot of rap & hip-hop) was impressed with what she 'felt' and heard while listening to her music in the passenger seat! The unit is housed in a sturdy aluminum enclosure (as a point of reference, the slightly more expensive Kenwood SW11 mentioned earlier was enclosed in plastic) and the overall build quality seems impressive. I'm hoping that's an indication of the unit's overall durability and reliability in the long term. As the old saying goes, "Time will tell," but in the interim, "So far, so good!"
