RockvilleRTB12A 12" Powered Subwoofer Bass Tube, 600W Peak, Deep Bass, Built-In Amp, Crossover, Bass Remote, Vented Enclosure, Perfect for Car Audio

Easy hookup too, power, ground, remote, 2 rcas and you're good to go!

Amazing sound for the money. I like that its all in one compact and easy to install. Also i have in my 2002 escalade and it fits perfectly without losing my 3rd row seating! Would buy again

I purchased this for a 2014 Ford focus with factory 6 speaker stereo, set up was very easy with only tough part being the powerwire through the firewall of the car. I used fuse location f85 for the remote wire and a pac line in off the front speakers for signal and it works great. Edited to note that the speaker just died apparently all wires working even purchased a new line out for signal and still no sound so it has to be the speaker.

Install was easy, comes with a pigtail to hook up to stock stereo speakers so you don't have to pull head unit. Clean bass doesn’t drown out mids and highs. For 150 dollar system cant beat it. Make sure to sand the paint off where you ground it, make sure you pay attention to pos and neg if youre using rear speakers as the signal to amp. People hating on it probably didnt hook it up properly. Its not gonna slam or vibrate everything but you will be heard coming from a block away. Everything seems high quality, all in all good compact system that wont break the bank.

I’m not exactly sure what people expect for less than 150 bucks but this thing is an impressive bump in a small suv, don’t be expecting to drive through the neighborhood annoyingly knocking peoples photos off the wall or rattling grandmas precious moments collection but for what it is I don’t think you can find better. Has rca hookups or you can tap into your factory speakers using the included hi level plug and make sure you strap it in or it will be bumping to more than your music. Overall good buy

First impressions, it looks great! It does have nice carpet and is pretty sturdy. I will state now that I have stepped down from two JBL stadium 12s so that I could get some room back for groceries. That being said the sound quality is ok, the volume is underwhelming. The four door speakers my vehicle has easily overpowers the bass. It sounds like an ok factory subwoofer. All of the reviews I read prior to making this purchase made it sound like it was going to be surprisingly loud, but alas no it is not. I could see this fitting well in a small hatch back or like a extended cab truck. If you don't have a factory subwoofer it would definitely round out your overall sound, for the price is not bad but not great.

The speaker sounds great in my 2 seater.. All the necessary bass you need.

This thing is amazing. I had previously purchased the 8" MTX RT8PT, since I only have a small BRZ so I figured why not try it out. Even at everything on max (except the frequency) that thing barely tickled anything. I returned that and hooked this up and it's 4 times what the MTX was. I actually have everything set to half (except, of course, the frequency) and it's absolutely everything I wanted, for 2/3 the price. I'd give this thing 10 stars if I could. The reviews don't lie. This thing rivals some of my old systems from years ago.
