Dimensions
CRUX does not provide verified physical dimensions or weight for the SWRSU-38B on its official current product page.
Some marketplace listings show approximately 9 × 2.5 × 1 in, but this appears to be marketplace/package data and should not be used as confirmed module dimensions.
For Walmart/eBay assembled dimensions and weight, physical measurement is the safest option.
Performance
The SWRSU-38B interfaces the Subaru factory wiring with an aftermarket head unit while preserving compatible steering-wheel controls.
The module uses DIP-switch settings based on both the aftermarket radio brand and the manufacturer/configuration of the original Subaru radio. CRUX provides specific settings for Panasonic, Clarion and Fujitsu Ten factory radios.
