I have several brand New 10 inch 300 watt slim powered subwoofers.
They are very narrow to fit in tight places. Behind seats in a single cab, under seats or just take up little room in any trunk. The inputs have auto impedance sensors and built in converters to be hooked up off your rear speaker wires or can use RCA cables from your aftermarket deck.
Model With grill $120
Model Without grill $100 Slightly thinner to fit in tighter places
Purchase more then one subtract $20.
Prices are firm.
