VMInnovations offers the refurbished Kicker CompS 12" Enclosed Car Subwoofer for $117.95. Coupon code "DEALNEWS" cuts that to $112.05. With free shipping, that's $18 under the lowest price we could find for a new unit. It features 50- to 300-watt RMS power (600-watt peak), 27Hz to 500Hz frequency response, and 4-ohms impedance.

Note: A 90-day warranty is included, but it's unclear who backs it.
