Review: Buy it! - 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!
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!

## 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.

### ⭐⭐⭐⭐⭐ Great addition to round out the low end!
*by D***S on March 19, 2023*

This sub produces clean bass that pairs very nicely with my JBL components running off a high-powered Sony receiver. I put this in my 2007 Prius in 2018. My daughter now drives the car and the whole system is still running as strong as ever. I can't tell you how impressed I am with this sub with the sound quality and the life span of it. I am planning to use this (or the SS10P version) in the next car I am about to get. I am a little bit of an audio snob in general. I can get really picky over audio at times. I also used to have a decked-out car audio system with everything amp'd and the big sub in the trunk in my younger years, so I have some experience in this area as well. I have found I can't handle a lot of bass rattling my body anymore. It makes me sick. :/ I still want that low-end punch, but without too much shaking of the body. This little guy fits that bill on a smaller car like a Prius perfectly. It will rattle my rearview mirror but doesn't make me sick. I tested this against the older model Rockville RW10CA 10" under-seat sub wondering if I wanted more bass. The 10" option was too much bass for what I was looking for, but more importantly to me, it was too muddy sounding. It gave a lot more rumble but wasn't clean and tight. I wouldn't have minded the extra headroom on the days I wanted to push the bass a little more, but I stuck with the 8" because it just sounded cleaner (they didn't have a 10" version of this SS series then). I am very interested in the 10" version hoping it is just as clean with that headroom I sometimes want. Be warned, if you turn it up too loud it will distort. My daughter likes to turn on bass boost sometimes and I instantly know it is on when I get in. I turn it back off. It can rumble more, but it just sounds like a mess at that point (like any speaker that distorts). If you want some nice, clean low-end that will rumble the car decently without drowning out the highs, get this. If you want more chesty feeling bass, I think the 10" version will be more to your liking. It's double the RMS power as well. I just hope it's as clean!
