Review on Powerful 6 Inch Ultra-Thin Subwoofer: Under Seat Car Bass Amplifier with Low Sound by Marc Farrell

The box is sturdily folded and very nicely covered. I'm using it as parts for a custom speaker box, so I've taken it apart and can check out the structure. The amp is durable, with an aluminum heatsink. Both speakers are connected to the same output with a low-frequency capacitor in series with the tweeter. Both speakers are well made, with a near-full-diameter, single-magnet woofer measuring 6 inches and 3/4 inches thick. None of the internal components are branded. Generally a quality item.
