W10k9D4 sub

"I have a 2000 rms 2 channel amp @4 ohms and it’s not moving the sub. Still sounds great the bass is deep and tight. Looking to upgrade my amp to a taramp 3000 watt."

— Orlando M. (5/5)

Great value subwoofer

"Bought this to pair with a Polk Audio amp, wired for 800W at 2-ohms in a purpose-built enclosure for my 2015 Mustang GT. So far am really pleased with how the sub sounds to complete the sound that was lacking from the OEM 9-speaker Shaker system that has no sub."

— Chris A. (5/5)

Awesome craftsmanship

"My sub wiring kit and capacitor are impeccable in quality."

— Christopher B. (5/5)

"Works great!"

Satisfied

"This purchase was a replacement for a Rockville subwoofer with less wattage. The replacement brought about 100% satisfaction! Excellent sound and can handle the high wattage of the amp and volume of the stereo with zero distortion. So happy with the speaker, ease of purchase and fast delivery."

— Rossalind H. (5/5)
