Punch Single 12インチ 300ワット アンプ内蔵サブウーファー

Space was tight in my trunk and this sealed 12” enclosure fits perfectly without sacrificing all my cargo room. The 300 watts of built-in power is plenty for a factory system upgrade, and the bass hits clean without rattling the panels.

The sealed enclosure makes it a true one-box job—no separate amp to mount or wire up. Took me about an hour to tap into the rear speakers and it’s been thumping clean ever since.

For a factory radio with no preamp outputs, this thing is a godsend—the built-in amp makes hookup a breeze since it's all one unit. I was honestly surprised how much punch the 12" driver adds to my trunk without taking up half the cargo space.
