Our take on the Cerwin Vega 8" Underseat Enclosure with Dual Output

This is a powered shallow-mount subwoofer enclosure that fits under a seat, with a built-in amplifier driving the sub and four full-range channels for other speakers. It is aimed at drivers who want more bass without giving up cargo or foot space, and it can anchor a system built from scratch or fill in a factory setup. The 70W RMS per channel and 870W peak rating put it in the same class as other underseat powered subs, but the four extra amplified outputs are unusual at this size. Owners of compact underseat subs often note that deep, loud bass is limited by the shallow enclosure, so expect a solid low-end lift rather than window-rattling output.

What reviewers say

Owner feedback on underseat powered subs of this type is generally positive on space savings and the convenience of an all-in-one unit. The common complaint is that shallow enclosures cannot match a full-size box for deep bass output.

What people mention
  • Bass outputMixedOwners say it adds real low-end punch but cannot match a full-size sub box for very deep bass.
  • FitPraisedThe shallow enclosure tucks under the seat and preserves cargo and legroom.
  • InstallationMixedBuilt-in amplification simplifies wiring, though setting gains and the bass enhancer takes some tuning.
  • PowerMixedThe four full-range channels are handy, but 70W RMS each is modest for demanding speakers.

About the Cerwin Vega 8" Underseat Enclosure with Dual Output

This is an amplified 8-inch underseat subwoofer enclosure for trucks, cars and other vehicles. It has a shallow design for mounting under a seat. It has a dedicated subwoofer channel and four full-range output channels, so it can also power additional speakers.

The amplifier delivers 70W RMS per channel across 4 channels, with a peak output of 870W. Input sensitivity is adjustable. It accepts low-level, 20V high-level and 20V line-level inputs over wired connections, so it can be used to upgrade a factory audio system or as the start of a new one.

The VEGA BASS bass enhancer adds bass boost. LED indicators show power, protect and status.

Questions and answers

Will this fit under my truck or car seat?
It is about 12.4 inches wide, 9 inches deep and 2.5 inches tall, so check the clearance under your seat before buying. Shallow underseat designs suit most trucks and many cars, but some seats sit too low.
Can I connect it to my factory radio?
Yes. It accepts high-level inputs, so it can take speaker-level signal from a stock head unit without a separate line-out converter.
Does it power my door speakers too?
Yes. It has four full-range amplified output channels in addition to the dedicated subwoofer channel, so it can drive cabin speakers as well.
How much bass should I expect?
Expect a solid low-end lift that fills out music in the cabin. A shallow enclosure cannot produce the deep, loud output of a large sealed or ported box.
What is VEGA BASS?
It is Cerwin Vega's bass enhancer circuit that boosts low frequencies. Use it sparingly, since too much boost can muddy the sound and strain the sub.
What comes in the box?
The enclosure with its built-in amplifier and subwoofer, plus wiring and mounting hardware for installation. Check the listing for the exact included accessories.
