Review on Lanzar 10-inch Car Subwoofer Speaker: Premium Sound System Upgrade with Non-Pressed Paper Cone, Stamped Plastic Basket, and Dual 4 Ohm Impedance - MAXP104D by Brandon Thompson

Not sure how much power they can actually handle but I've used around 500w RMS with no issues. The big downside to these subwoofers is that they use an insane amount of volume to get the right setup with the cabinet. I highly recommend setting the box in the low 30's and as loud as possible. In the right box, these things can produce good bass. With that in mind, the airspace requirements and equipment of the submarine are primarily the reason why I only want to give her 4 stars instead of 5.
