1994-2001 Dodge Ram 1500 2nd Gen (BR/BE) — subwoofer box fitment

Confidence badges say how well each figure is sourced — this is research, not manufacturer spec.

Body styles covered: Regular Cab, Club Cab / Extended Cab, Quad Cab (1998-2001)

Before you cut anything

Measure your own vehicle. Trim levels, factory subwoofer options, and mid-generation changes all move these numbers, and a box cut to a researched figure that does not match your truck is wasted wood. Where a badge reads Unconfirmed, treat the value as a starting point for your own measurement, not as an answer.
