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

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!

Let’s be honest, if you’ve made it all the way to the reviews you know what your looking for. A small sub that fits where you need it to and provides a good sound. You already know that it’s not going to rattle your teeth out or break any windows… I bought this to fit under the drivers seat in my 2006 Honda Ridgeline. It fits perfect, I installed it in one night and felt like it was pretty simple. Installing amps and subs is not easy, this install was exactly how I thought it would be. Running wires all over the place and getting behind the deck, but nothing out of the ordinary. Now for the sound, it’s great! Like I said before, it will not rattle your teeth out, but it does provide a nice addition to the lower end. My advice is to take all the bass out of your factory speakers, set the sub at 80hz and let it handle the low end frequencies. I have an aftermarket deck that allows me to do that. Overall I’m very happy with the cost, value, size and sound!

Great value for the money. Don’t expect it to transform your car into a concert venue but it greatly increase your cars bass. It was relatively straightforward to install, all you will need to buy is a few things to get it done right. Appropriately length wires, and connectors. The size really does fit under pretty much any car, as mine is a tiny Hyundai.

This is an excellent subwoofer for anyone looking to add bass to their system inexpensively.The fit and finish of the device is excellent. It's aluminum with a hammered finish and a good looking design that's not too flashy or in-your-face; I'm kinda disappointed I have to hide it under the seat.Wiring it up wasn't bad, but could be better. I used the RCA cables to connect it to the Sub output on my head unit, and the power connectors come from an 8-pin connector (which is also where you'll find the high-level inputs). You're supposed to somehow connect the thich 8-gauge wire to two smaller wires on the 8-pin, which isn't super easy, especially if you don't have a powerful soldering iron. However, the included cables are awesome. They have a nice thick PVC insulation yet they're super flexible, even the thick 8-gauge power wires (I think its 8 ga, not 100% sure tho). To attach it to the car, I just drilled holes through the floor and screwed it in place. The included screws were a bit short, so I had to use longer ones I had lying around. If you drill through metal, make sure to paint it or something (especially if its exposed to the elements) otherwise it'll rust.Once its wired up, it sounds awesome. bass is crisp but quite strong. I like the bass to be a bit heavy and this speaker totally delivers. If you're looking for something that rattles your license plate and can be heard from outside your car, this isn't it, but if you want to add a pretty good amount of bass, I highly recommend it.It also comes with a little bass level remote control, which I highly suggest you install. some songs sound better without so much bass IMO, so it works great to easily adjust the amount of bass according to the song. It does have one of thouse ultra bright annoying blue LEDs tho, so keep than in mind when mounting it. However, the sub works perfectly fine without the remote.The only real downside is that both the connectors and the adjustment knobs are on the same side, so you can either mount them all in a visible location, making it easy to adjust the sub, but also making it a bit uglier since the wires will also be visible, or you can hide the connectors for a cleaner look, but adjusting anything will be a pain (I have to go from the front of the seat with a tiny screwdriver and adjust everything by feel).

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!"
