Description
PWS8D2 — 8-Inch Echo Pro Shallow Subwoofer — DVC 2Ω — 250W RMS
PWS8D2 is the 8-inch choice when mounting depth is the hard limit. At only 2.90 inches deep, it can solve an under-seat, behind-seat or shallow-panel install that a standard PW8 simply cannot fit, but the tradeoff is lower power handling: 250W RMS instead of the standard-depth PW8's 400W RMS.
Choose D2 when one shallow 8 needs to wire to 1Ω or when a pair is being planned around a common 2Ω final load. SMS would use PWS when the extra inch-plus of motor clearance is more valuable than the additional thermal headroom of the normal-depth PW line.

BASS SYSTEM FIT
Where this fits in the build
The subwoofer is only one part of the bass system. Enclosure volume and alignment, final impedance, amplifier power, vehicle space and electrical support all affect the result.
Plan aroundChoose the bass target and usable space first.
Match itMatch the enclosure to the driver instead of treating the box as an afterthought.
Finish itMatch final load, amplifier and electrical support to the complete bass plan.
