Rockville USS10 800W 10″ Slim Under-Seat Active Car/Truck Subwoofer, Built-in Amplifier, High-Level Inputs, Remote Bass Knob, PWM Power Supply

Great bass.
Easy installation, fantastic sound, easy to setup. Great build quality. If you want a little low end fill, without a giant box in the back seat or trunk, this is a terrific solution. Fits incredibly well under the driver’s seat in my first generation Tundra.

Great sound but not quite “under-seat” for me.
Fitment/quality: I have a 2000 Jeep Cherokee XJ and it was too big to go under the seat. It’s not really an issue though as I have plenty of room in the cargo area for the speaker. I measured before I purchased either way so this was not a surprise upon installing. I used some heavy duty velcro to secure it to the carpet behind my rear seat and it doesn’t move at all. This makes it easier for me to relocate the speaker when I need to. This would also be a great trunk solution for a sedan. The build quality seems very solid and durable. The aluminum housing and metal speaker grill feel sturdy and looks pretty nice too.As for the sound: I couldn’t be happier. I wasn’t looking for booming bass (although this sub will rattle your windows and anything else not securely fastened if you crank it all the way up) But if you’re looking for compact/slim subs then you’re probably in the same boat as me. I have mine dialed in to really round out the sound that my aftermarket stereo system was lacking. I can’t say enough how happy I am to have chosen this one. I really look forward to driving now because of the sound quality of the stereo in my Jeep. I didn’t use the remote level control since my head unit has sub level and EQ built in so managing the sound from the receiver was a better option for me. Installation was standard like installing any other amp. It took me less than an hour to do myself.

Worked for awhile.
Easy install. When it worked it sounded great. One day out of the blue something internally came loose causing the circit board to short out. Was unrepairble.

Never again.
I would leave 0 stars if I could. I purchased this item to provide some bass in my single cab Silverado. It is mainly a farm rig I’ve been keeping pristine, so it doesn’t get daily use. I had originally planned on an under the seat installation, but once the product arrived I realized it just wouldn’t fit. From there, I mounted the Subwoofer on the hump between the driver and passenger floorboards. Once installed I was impressed with the fullness of the sound and the bass it added, but this was short lived. On its first real road trip, I played it continuously for maybe an hour and not even close to max volume. I was also conservative on my amp settings because I mostly listen to country and rock music. I stopped to fuel up, and when I turned the vehicle back on the subwoofer had become so damaged that it clipped constantly and was unbearable to listen to. I reached out through Amazon to try to rectify the problem and was issued a return label. Once I shipped the product back I never heard another word. No replacement, no reimbursement, nothing. My recommendation would be to go another route or you’ll be out $150 just like me.

no tiene cuerpo y embarra los bajos como si todo fuera flat. esta bien por el precio y el tamaño pero vale la pena pagar mas para algo mejor

Despues de 2 meses de uso, simplemente dejo de funcionar, ahora voy a ver como puedo solicitar la garantia

I picked up 2 of these for my wrangler tj and they definitely work good but I’d call these mid woofers before I’d call them sub whoofers. I understand that because they are a slim design they won’t hit hard low notes but I was definitely expecting alot more hit from these. Will probably end up pulling them out of the vehicle and sacrificing some cargo space for a proper sub and amp.
