2008-2014 Dodge Avenger Subwoofer Box Fitment

2008-2014 Dodge Avenger 2nd Gen (JS) — subwoofer box fitment

What we researched for this specific generation: where an enclosure actually fits, what the factory speakers are, how the factory audio is wired, and which real builds and commercial products exist for it. Confidence badges say how well each figure is sourced — this is research, not manufacturer spec.

Body styles covered: 4-Door Sedan

Mounting locations

Trunk Likely

trunk, up under the rear package tray (NET Audio box)

Chrysler's 2008 launch kit: 'Luggage volume in the trunk is a competitive 13.35 cubic feet' (no SAE label). NET Audio describes the Avenger trunk as 'a large trunk for a small car' and its box as made to 'fit up under the rear package tray'. Rear seat is a 60/40 folding bench (Stellantis 2008 launch kit). EPA's own records give a luggage volume of 16 cu ft for the 2008 model year and 13 cu ft for 2014; for 2008 the two sources disagree, and both are given here.

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.
