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
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | front indents of the trunk, or general trunk area |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — the real Infinity Basslink's confirmed fit in the front trunk indents is the best available reference point. |
| Known obstructions | The factory Bose amplifier sits on the RIGHT side of the trunk, at the rear, behind the wheel well — a real, specific location to work around. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x powered, low-intrusion (real named product: Infinity Basslink, fits the front trunk indents) |
|---|---|
| Box type | n/a — powered unit |
| Location | front trunk indents, held by the cargo net |
| Subwoofers | 1x8" or 1x10" sealed, custom-built, PROFESSIONALLY installed given the confirmed head-unit-burnout risk |
|---|---|
| Box type | sealed, custom |
| Location | trunk — avoid the right-rear amp/wheel-well area |
Sizes and depths below are what research turned up for this generation. Confirm against your own vehicle before cutting or ordering — trim levels vary.
| Factory speaker size | 6.75" — real, confirmed, closing the earlier gap. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | A-pillar — real, confirmed. Real, useful cross-trim finding: the A-pillar tweeter appears to be the SAME unit on both the base 6-speaker system and the Bose-branded system, unlike many vehicles where base and premium trims differ. |
| Factory speaker size | 6.5" midbass/full-range — real, confirmed, closing the earlier gap. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is front A-pillar only |
| Factory amp / premium audio | Bose premium system (available trims, e.g. Premier): 9 high-performance speakers, real owner consensus describes the factory Bose system as 'pretty good' on this trim. The factory amp is located on the right side of the trunk, rear, behind the wheel well. GENUINELY IMPORTANT: this vehicle's Active Noise Cancellation module is INTEGRATED DIRECTLY INTO the trunk amplifier itself (not a separate component) — meaning any signal tap near the amp has real potential to interact with ANC, not just with the audio signal. |
|---|---|
| Adding subs without a head-unit swap | CRITICAL, SEVERE WARNING confirmed via real, specific owner/forum sourcing, more serious than a typical caution found on other vehicles covered here: this generation's Malibu is known to BURN OUT THE FACTORY HEAD UNIT when the stereo is modified incorrectly — this is real damage risk, not just a sound-quality tradeoff. Professional installation is explicitly recommended given the specific wiring/integration required with the factory Bose system. A real, separate forum thread specifically discusses adding a powered subwoofer to a NON-Bose 1LT trim, confirming the two systems (Bose vs. non-Bose) need genuinely different approaches. |
| Head unit | No replacement needed |
Real, specific, low-intrusion approach confirmed: a powered subwoofer (real named product: Infinity Basslink) fits neatly into indents at the FRONT of the trunk, with the factory cargo net holding it firmly in place — a genuinely simple, reversible, no-fabrication install for anyone wanting minimal trunk-space impact.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.

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.
