Best OverallA slim powered subwoofer with a built-in amplifier that fits under many seats. It accepts RCA or speaker-level inputs and includes a bass remote and wiring, but it is built for modest bass and a single driver.
An all-in-one powered subwoofer with a sealed enclosure, a built-in amplifier and a remote level knob. Output is modest compared with a separate sub and amp setup.
A self-contained powered sub box for trucks and SUVs, with a remote control. It is mono, not waterproof, and the listing gives no input voltage.
A down-firing truck or trunk subwoofer enclosure with high power handling at a low impedance. It needs a separate amplifier, and it is not water resistant.
Popular PickA slim powered sub with its amplifier built in and a wiring kit included, aimed at cars and trucks with little room. It is mono and not waterproof.
A pre-loaded slim subwoofer in a wedge-shaped box made for single-cab trucks. The listing shows no amplifier, so one has to be bought separately.
A smaller slim sub box with a lower output than its bigger sibling. It suits tight spaces, but no amplifier is listed.
Two loaded subs, an amplifier and wiring arrive together, so it suits drivers who want a ready system. The enclosure is wide and nothing about it is waterproof.
A slim powered subwoofer with an integrated amplifier, remote bass knob and both input types. The title and description disagree on maximum power, so use the RMS rating.
An amplified low profile subwoofer built for cars with little space, with remote level control and several tuning filters. It is not a passive driver, and it needs a vehicle power supply.
A complete bass package with twin drivers, a matched mono amplifier, a wiring kit and a dash remote. It is heavy and large, so plan trunk space and a strong electrical supply.
A compact amplified bass tube that adds low end without a separate amp or a built box. Output is modest, and the listing gives no impedance figure.
A slim powered subwoofer that tucks beneath the driver seat, with a built-in Class D amplifier and a wired level remote. The listing names no vehicle fit list, so measure the space under the seat first.
A pre-loaded dual-driver ported enclosure from Skar Audio for cars. No amplifier is listed, and some of the listing data is clearly wrong, so check the maker for a full spec before wiring.
