Small enough to fit in behind my F150 seat. Adds just enough bass to make us sound good. I have the gain set low, and at full volume it still sounds great. Not going to win any competitions, but for a clean upgrade from the factory sub this is worth the money.

This review is a little long but I wanted to help others that have the same goals that I did. I have a 2022 F-150 SCREW and was disappointed with the sound from the base line non B&O 7 speaker system. First thing I did was upgrade the speakers by installing the Infinity Reference - REF-9630CX 6x9 2-Way Component System, and REF-6532IX 6.5" 2-Way Car Audio Speakers Package. The sound and clarity difference was exactly what the truck needed. I listened to this setup for about 2 months and decided the bass just wasn’t what I wanted. In my 2011 SCREW I had an under seat sealed enclosure with 2 kicker 10's and was extremely happy with it's performance. Going to this smaller single 10 inch I knew I wouldn't get the same bass but was hoping for a little thump to fill in low frequencies that the infinity reference lacked. I knew I needed a subwoofer but also wanted to retain my under-seat floor space. I did a lot of research and chose the R2S-1X10 Prime R2S Single 10 because of other user reviews. By trimming one of the seatbelt mount bolts down and removing the back wall insulation to accommodate the sub box, it does fit perfectly and still allows me to stow the seat in the full up and locking position. I powered the sub using a Skar Audio RP-350.1D Monoblock amp and fed the RCA signal using the Kicker 46KISLOC2 Speaker Wire-to-RCA Line-Out Converter. I decided to not use the converters remote on signal because the newer vehicles don’t immediately cut off power when the ignition is turned off, instead I tapped into the passenger kick panel fuse box and used fuse 2, when the ignition is turned off, and I open my door, the amp immediately turns off. I am still working on perfecting the amp adjustments but I am amazed at the amount of clean bass that comes out of that little sealed box. If you are looking for some decent bass and keeping your floor open, this little box is the real deal.

Excelente desempeño, lo conecté con un amplificador planet audio Monocanal de 1500 watts y suena súper bien , fuerte y claro, lo puse en una L200, tuve que reacomodar el gato y la barra que sirve para bajar la refacción, pero quedó muy bien, sin duda lo recomiendo

Great sub for the price. It will fit behind the rear seat of my 2019 F150 crew cab and the seat will still fold up. You will need to trim out some of the insulation on the cab behind the seat. I currently have it under the rear passenger seat wired to a Kicker DX250.1 amp and it powers it perfectly. It’s not window shattering bass but it adds enough for what I like. The ford stereo is the worst on the market especially if you don’t have a factory sub. This more than makes up for it.

Components installed:- One Rockford Fosgate R2S-1X10 10-inch shallow loaded enclosure- Kenwood KDC-BT555U receiver/head- Boss R1100M monoblock amp- Sirius/XM SXV-200v1 tuner- Metra single DIN faceplate kit- Metra wiring harness adapterI wanted to use a local business for this installation, but they quoted me $750 to install $250 worth of components. So I decided to order the stuff from Amazon and do it myself. I got a much better head, a better amp, the Sirius/XM tuner (not included in the quote from the local vendor) and the same subwoofer/enclosure for less than $350. It took me parts of three days to do the install, but it was fun, I learned a lot, and I do quality work (even if I do say so myself).The bottom line is, the system sounds awesome. I had already upgraded the stock Infinity speakers in the front and rear doors with a set of Boston Acoustic speakers. I did this a few years ago when the stock speakers got wet or rotted and started buzzing. This gave me a tinny sound that had very little low end. That and the fact that I could not use my iPhone with this system finally prompted me to upgrade. I had never installed an amp before and didn't have the first idea what would be required. Luckily a lot of info is available on the Internet that makes this stuff doable.The local installer had told me that this size subwoofer enclosure would fit behind the smaller driver-side rear seat in my Dakota Quad Cab, but that turned out to be incorrect. The alternative is to spend an additional $200-$300 to purchase a molded enclosure, plus the cost of the actual subwoofer. So I decided to locate the enclosure on the rear floorboard, snugged up against the middle console, facing backwards. I am still in the process of trying to decide how to anchor it there--it's dangerous to have something that heavy not properly anchored down, as it could become the source of severe head trauma in a crash. I am thinking I'll probably use some combination of velcro and home-made brackets. The one thing I have noticed is that, if it is placed directly against the back of the console, the console will not lift up and out of the way in the front seat. This is a problem for me, because that's usually where I place my Glock when I'm transporting it but want to keep it out of view.. But, from a rear-seat occupant perspective, this configuration allows two people to still ride comfortably in the back, though it does extend slightly into each occupant's knee space. It pretty much makes the middle seat unusable though, so if you need that much passenger room, you will need to spring for the molded enclosures that fits under that seat. Luckily I rarely have passengers riding in the back.The hardest thing about the install was running the 8-guage power supply from the battery through the firewall into the pax compartment. Using Internet research, I located the wiring harness grommet on the driver's side, and was able to use a coathanger to get the wire through. I pushed the coathanger through and then electrical-taped the 8-guage power supply wire to the other end of the coathanger. First time it came loose, but second attempt worked like a charm.The wiring harness kit was pretty simple. The order is Kenwood wiring harness-->adapter kit from Amazon-->factory connections in my truck. The wiring is almost idiot-proof as it is pretty much color-to-color. The only discretion involved my truck's OEM amplifier--I needed to connect its control wire and the new amp's control wire to the single P-CONT wire from the new harness. If you understand that all these wires do is turn on the amps when the radio is powered up and turn them off again when the head unit is off, it's a no-brainer to figure out you just need to wire both control wires to this same wire in the harness.To test the connections, I twisted all the wires together and electrical-taped them. Once I confirmed everything was working, I took the harnesses back into my house and soldered them and used rubber heat shrink around the soldered connections. I prefer that to the cheap crimp connectors included in the 1100 amp wiring kit I purchased at Walmart.The one thing that nearly threw me off was the amp's "Protection" light that illuminated after I cleaned everything up and put the trim back on the interior of my truck. Luckily, I was able to search the Amazon user comments and learned that an improperly grounded amp is one of the causes. Sure enough, I removed the piece of trim under which I had connected the 8-guage ground wire to the body of the truck with a screw and saw that I had jarred loose the ground wire when I snapped that piece of trim back in. My advice is, if you get a "Protection" light on this amp, check the ground wire connection before you do anything else.I am amazed at the quality of the sound. The bass is amazing and it's almost like having a new truck. I highly recommend these components.
