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

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!

This little sub exceeded all my expectations! It’s not going to make the mirrors on the car next to you shake, but it definitely makes the bass sound better than any new factory system. I usually have it set at mid range and it’s more than enough bass. Very easy to install, too. Great product and great brand!

I ordered the 8" ss8p with the wiring kit since it would come all at once. 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.

Great sound and easy to install. Works great in my Ford Maverick
