. That's tied with our mention from a week ago as the lowest total price we've seen. (It's also the best price we could find by $22 for the subwoofer alone.) It features a 20Hz to 120Hz frequency response, speaker- and line-level inputs, and auto on/off. The 8-gauge kit includes wires, cables, fuse, grommet, terminals, connector, and zip ties.
Note: It's currently out of stock, but can still be ordered at this price for delivery when available.
