Size: 2 Ohm Style: Single Pack
I bought a single 18" and built a box for it and this subwoofer SLAPS. Very well made sub with a big heavy magnet, especially for the price. Running it with an American Bass 2000 watt rms amp with half tilt... it moves air and rattles my eardrums along with everything in the car... F.Y.I: Just make sure to buy a professionally made box or really know what you're doing if you make a box. This was my first box i made and within a couple of weeks this sub started ripping the internals of the box apart (ports) so I needed to go back into the box and use heavy duty caulk to fix everything. Sounds better than ever now. ... show more

  • Amazing value, sledgehammer bass
Size: 2 Ohm Style: Single Pack
Absolutely stunned by this sub. Hits like a semi truck. I'm powering it with the Skar 4600 for plenty of ceiling in terms of power. I would definitely get a big effing amp if you want to run this properly. Make sure you get a quality cabinet built custom for it or know what you're buying. I am blown away at the quality and sound for the price. Would definitely recommend this company to friends. ... show more

  • Do not hesitate!!! It is worth it!!!
Size: 2 Ohm Style: Single Pack
At first I was a bit skeptical, but don’t hesitate, it is a well built sub. I have a 2700 rms nvx pushing it and it can withstand a beating.
