Atrend Bbox A152-10CP 雙 10 吋密閉式音箱，適用於 99-07 Chevrolet/GMC 加長駕駛室

Had to trim my rear seat insulation just a hair, but once that was done the enclosure slid right into place and the latches still work perfectly. The downfire design keeps the bass clean without rattling anything loose.

Wasn't sure a sealed box would hit hard enough but these tens surprise me every time I turn it up. It drops right under the rear driver side seat without touching the seat latch, which was my main worry.

Fits my 2002 Silverado extended cab perfectly with zero cutting or drilling, which honestly shocked me. The downfire setup under the driver side rear seat doesn't interfere with the seat latching at all. Two 10s in a sealed box back there sound way tighter than I expected.
