Our take on the Epsilon Power Acoustik USW-80L Low Profile 8 Car Subwoofer Enclosure

The Power Acoustik USW-80L is a low-profile 8-inch subwoofer enclosure built to fit under or behind a seat where a full-size box won't go. It pairs a slim cabinet with a built-in amplifier, so it needs only power and a signal rather than a separate amp and wiring run. Output is modest compared with a conventional 8- or 10-inch sub in a larger ported box, but it adds low-end weight to a factory system without eating cargo space. It suits drivers who want a simple bass upgrade in a truck, hatchback or tight trunk, not those chasing high SPL.

What reviewers say

Owner feedback is limited, but the pattern is consistent: buyers like the small footprint and easy install, and accept modest output as the trade-off. Complaints center on bass depth and the limits of the built-in amplifier.

What people mention
  • SizePraisedOwners value the slim cabinet because it fits under or behind seats in tight cabins.
  • Bass depthCriticisedListeners say the low end is thin and does not reach the deepest notes.
  • OutputMixedIt adds weight to a factory system but is not loud enough for bass-heavy listening.
  • InstallationPraisedThe built-in amp means fewer parts and a quicker install than a separate amp and box.
  • AmplifierCriticisedThe onboard amp is seen as the weak link, with limited power and headroom.

Questions and answers

Will it fit under my truck or SUV seat?
It depends on the seat frame and floor clearance. Measure the space under or behind the seat and compare it with the enclosure's dimensions before buying; low-profile boxes still need a few inches of depth.
Do I need a separate amplifier?
No. The enclosure has a built-in amplifier, so you need power, ground and a signal from the head unit or line output converter. That is the main reason to choose it over a passive box.
How does it compare with a regular 8-inch sub in a ported box?
A conventional ported box will usually play louder and deeper. This enclosure trades output for a slim footprint, so pick it when space matters more than maximum bass.
Can I upgrade the subwoofer inside it?
The cabinet and amp are matched to the included driver, and the shallow interior limits what fits. Swapping drivers is not a practical upgrade path; a separate box and amp make more sense for that.
What do I need to hook it up?
An amplifier wiring kit with power and ground cable, a fuse, and a signal connection from your stereo. If your head unit has no subwoofer output, add a line output converter.
Is it good for rock and country, or only hip-hop?
It adds fullness to most music, but it is best at reinforcing kick drum and bass guitar rather than producing deep, loud sub-bass. Bass-heavy genres will expose its limits.
