Pioneer TS-WX400DA 시트 언더 서브우퍼 앰프 공간 절약형 자동차 베이스 박스 서브

Installed this under my passenger seat and it fits perfectly without taking up any trunk space. The built-in amp makes the bass feel tight and musical, not just loud.

Digital Bass Control really does make a difference — even at low volume the bass stays tight and punchy instead of muddy. It barely takes up any floor space under my passenger seat. Sounds much cleaner than the factory system ever did.

Took me about an hour to tuck it under the passenger seat, and the built-in Class-D amp makes the 250 watts hit way harder than the size suggests. The digital bass control is a lifesaver for dialing it in without knocking my mirrors loose.
