Great Value

Very good product 100% satisfied, highly recommended for other customers out there.

Hits just right!

Just got it and sounds great in my Suburban, only have one hooked up to an Autotek ATA800.2 2-channel 800-watt max 4-ohm bridged amp and couldn't be happier, got the Belva 4-gage kit and I have no dimming and volts stay constant, If you do the math for the RMS range its a great set up.

Get what you pay for.

Sounded awesome for 30secs then heard a tapping sound. To find out the ridge separated from the speaker basket. Id suggest grill covers itll help hold the speaker together lol

Great subs for price

These subs work great sounds just as good as more expensive brands I recommend matching a pair with 2000 watt max boss amp high end amp might blow them they handle 200 rms not 500

Sounds great, especially for the money!

Replacing a subwoofer box in my other vehicle I needed only something simple and very affordable. Well this sub sounds like the pricy subs. I don't throw a ton of power at it, but in a single enclosure with my Polk amplifier it sounds great. Been using it for about 2 weeks so far. So far, great!
