  • Awesome subs
Size: 10" Style: Dual 2 Ohm
They sound great, hit hard with more bass than I can use. These sound as good as Skar with a better price. Would definitely buy again

  • Great quality and sound
Size: 10" Style: Dual 2 Ohm
Great quality product. Puts out a good amount of bass for the size. Shakes my whole crew cab of my GMC sierra. Highly recommend

  • Substantial improvement
Size: 8" Style: Dual 2 Ohm
Replaced the JBL sub from a Tacoma with this. Sounds great with the factory amp. Well worth the money. Mounting holes didn’t line up but just drilled new ones and works like a champ. Also found pigtail connectors on Amazon to plug into the factory wires inside the in closure.

  • Loud!
Size: 10" Style: Dual 4 Ohm
Hooked this up to a little 24v battery powered Bluetooth Amplifier for a speaker box build. Vibrates the floor below and above. Very pleased so far. Immediately bought an 8 inch for another build.

  • Zoom a Zoom Zoom Zoom & a Boom Boom
Size: 10" Style: Dual 4 Ohm
Solid entry level subwoofer with a good foam surround. Sounds stellar in the single 10" ported enclosure tuned to 32Hz.

  • Fast shipping. Easy installation
Size: 8" Style: Dual 2 Ohm
Like 24 hour delivery. Put one 8” in a 2002 Chevy Tahoe. Had to modify speaker box a little. This speaker is great. Brings out the bass and drums great. That’s all I wanted

  • Nice little sub woofer!
Size: 8" Style: Dual 2 Ohm
Speaker arrived in a timely manner, works really well, its a little thicker than I would have liked but that was my fault for not taking out the original speaker and measuring it first! other than that it sound great! I installed this speaker in a 2005 Toyota 4Runner in place of the stock JBL sub woofer in the right rear panel. ... show more
