Does anyone know for a fact how large the speakers are in the 8P S3 withOUT Bose? Is it the same as the one in the Bose document I found? 8 high-performance speakers One 5x11-cm mid-high-range speaker (centrefill) in the instrument panel. Two 3.5-cm tweeters in the a-pillars. Two 16.5-cm low-mid-range speakers in the doors. Two 16.5-cm low-mid-range speakers in the rear side panels. One 13-cm Richbass® woofer in a 9.7-litre custom-engineered bass enclosure in the left side panel of the trunk. System electronics Digital amplifier mounted in the right side panel of the trunk. Includes Bose digital signal processing, AudioPilot® noise compensation technology and 5 channels of customised equalisation. AudioPilot® microphone mounted in the ceiling-mounted control panel monitors interior noise level. Need to know because I'm getting an Alpine system fitted and I want to know if 6" speakers will fit in the doors, or if I'll have to stick with 5.25" like the 8L series... Cheers guys.
