- Enclosure: 503 × 378 × 318 mm. Allow room for mounting and access.
Will it fit my vehicle?
This is a boot-space enclosure, not an under-seat unit. We check secure mounting, power-cable routing and the signal connection to your factory or aftermarket stereo.
Send your registration and a photo of the stereo. We confirm any adaptors, wiring and labour before payment. No vehicle-specific fitment is claimed until checked.
