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: 2-Door Coupe (targa), 2-Door Convertible, 2-Door Hardtop (1999-2000)
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | coupe rear hatch area (convertible/hardtop figures in the same block) |
|---|---|
| Outer bounding box | Coupe: 35"W x 11"H x 35"D. Convertible and hardtop: 45"W x 22"H x 10"D. NOTE THE SOURCE PRINTS THE CONVERTIBLE FIGURE AS "45" W x 10" D x 22" H" — depth before height, which is not the order it uses anywhere else. |
| Known obstructions | COUPE: 11" of height is the limit, and if the car has the removable roof panel that panel has to go somewhere. CONVERTIBLE/HARDTOP: depth is the killer at 10" — it is a wide, tall, shallow slot rather than a box-shaped space, so a conventional enclosure will not sit in it. AXIS-ORDER CAVEAT WORTH READING: because the source printed depth before height only for the convertible, it would be easy to transpose them into a 22"-deep space that does not exist. The reading used here is confirmed by the source's own statement that the coupe has MORE room than the convertible — which only holds if the convertible is 10" deep and 22" tall, not the reverse. |
| Usable volume estimate | 1.8 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | Compact powered subwoofer — Crutchfield's explicit recommendation for this car across all three body styles |
|---|---|
| Box type | powered enclosure |
| Location | coupe hatch / convertible rear area |
| Subwoofers | 1x10" shallow sealed in the coupe's hatch area, built to 11" of height |
|---|---|
| Box type | shallow sealed |
| Location | coupe rear hatch area |
| Subwoofers | Coupe only, and custom: 35"W x 11"H x 35"D is workable for a single shallow 12". The convertible and hardtop are effectively out at 10" of depth |
|---|---|
| Box type | custom shallow |
| Location | coupe rear hatch 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 | 8" WOOFER plus a 3-1/2" TWEETER behind each door panel on Bose cars. The tweeters are radio-powered; THE WOOFERS ARE NOT — see known_obstructions, because the woofer is the reason this car is hard. |
|---|---|
| Known obstructions | THE 8" WOOFERS ARE ACTIVE AND PROCESSED, WHICH IS THE WHOLE PROBLEM. Each woofer is powered by a SMALL AMPLIFIER INSIDE ITS OWN ENCLOSURE, and the woofers are tied into a BOSE SIGNAL PROCESSOR that tunes the sound for the Corvette's unusually snug cabin. The source states the consequence directly: the stock Bose woofers WILL NOT PLAY WELL WITH AN AFTERMARKET RECEIVER. So changing the head unit on a Bose C5 degrades the woofers you kept, and changing the woofers loses the built-in amps — either way the front stage needs rethinking as a whole rather than upgraded piecemeal. Fitting an aftermarket speaker means DRILLING NEW SCREW HOLES into the woofer's factory bracket, which the source calls the toughest part of the job. Tools: panel tool, small flat-blade screwdriver, 1/4" socket, ratchet, extension, Torx T-27 driver. |
| Adapter bracket needed | The factory bracket is reused but must be drilled for new mounting holes |
| Tweeter | Behind the door panel, alongside the 8" woofer. Bose cars carry a BOSE LOGO ON THE DOOR SPEAKER GRILLES — that is the quickest way to identify the system without removing anything. |
| Factory speaker size | None — two-door car. Rear speakers live in the roof area on the coupe and the side panels on the convertible (see other_speaker_locations). |
|---|---|
| Known obstructions | n/a |
| Adapter bracket needed | n/a |
| Factory amp / premium audio | Base and BOSE systems. The BOSE AUDIO SYSTEM CAME STANDARD on the coupe and convertible, and was OPTIONAL on the hardtop that arrived in 1999 — so a Bose badge is the norm on this generation rather than the exception. Identification is easy: a BOSE LOGO ON THE DOOR SPEAKER GRILLES. The Bose system is genuinely active — each 8" door woofer has its own small amplifier inside its enclosure, and those woofers run through a BOSE SIGNAL PROCESSOR tuned for the car's tight cabin. The 3-1/2" door tweeters and the rear speakers are powered by the radio instead. HEAD UNIT IS REPLACEABLE, unlike the C7, and both single-DIN and double-DIN fit — with conditions, below. |
|---|---|
| Adding subs without a head-unit swap | Yes, and on a Bose C5 it is strongly the better path — because replacing the RECEIVER is what breaks the factory woofers (see below), a trunk or hatch sub with its own amp leaves the processed front stage intact. |
| Head unit | No replacement needed |
THREE BODY STYLES, TWO FIGURES. COUPE: 35"W x 11"H x 35"D. CONVERTIBLE AND HARDTOP: 45"W x 22"H x 10"D — much wider and taller but only ten inches deep. The source's own framing is that the coupe's space is "not much, but it's still more than" the convertible/hardtop, which is arithmetically true (13,475 vs 9,900 cubic inches) and is what confirms the unusual axis order it printed. Crutchfield recommends a powered subwoofer on this car rather than surrendering what little luggage space exists.

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.
