Rockford Fosgate Power 10" Slim 1000 Watt Single 1 Ohm Subwoofer T1S1-10

Need bass but don't have a lot of space? How about more power handling than your average shallow subwoofer? Well, this T1 "Slimline" subwoofer is not your average shallow, This Power Series T1S1-10 subwoofer uses a neodymium motor structure with high-strength magnets to help minimize mounting depth. It all adds up to power handling of up to 1000 watts max in a shockingly small package. The Vertical Attach Surround Technique (VAST) increases the speaker's effective radiating cone area without increasing the size of the basket.

The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted. This sub's 1-ohm impedance makes it a great candidate for multiple sub setups or for getting max power from high-performance mono amps. You'll love the big bass sound these subwoofers deliver, and you'll appreciate the slim design when you're looking for a place for bass in your vehicle.
