Oldsmobile Bravada Speaker FAQ

Should I replace dashboard speakers first in my Oldsmobile Bravada?

Start with the 6.5 inch door speakers instead. Dashboard speakers handle mid-range frequencies around 200-8000 Hz but door speakers carry the full frequency load. Your Bravada's door panels can accommodate both coaxial and component systems - components will give you better imaging since tweeters mount separately. Dashboard units are typically 15-25 watts RMS while door speakers handle 50-75 watts. The 4 x 6 inch dashboard speakers in earlier Bravadas have limited bass response anyway.

What's the difference between coaxial and component speakers for my Oldsmobile Bravada doors?

Component speakers separate the tweeter from the woofer - tweeter mounts in the door panel triangle or A-pillar. This creates better stereo imaging since high frequencies come from ear level. Coaxials mount everything in one 6.5 inch frame, easier installation but... the tweeter sits lower near your knees. Components typically cost $100-300 more but handle 20-100 watts RMS versus 15-50 watts for coaxials. Your Bravada's front doors support both types. Rear doors might need coaxials unless you want to run wire for separate tweeters.

Can I use the same speakers in front and rear doors of my Oldsmobile Bravada?

Yes, both locations use 6.5 inch speakers. But consider different approaches - components up front for imaging, coaxials in back for fill. Front door speakers should handle 4-8 ohm impedance with 75+ watts RMS since they carry most of the stereo load. Rear speakers can be lower powered, maybe 25-50 watts. The Bravada's factory wiring probably runs 4 ohms throughout. Some people skip rear speakers entirely... depends on whether you carry passengers regularly.

Why did Oldsmobile change from 4 x 6 to 3.5 inch dashboard speakers in the Bravada?

Dash redesign probably drove this change. The 4 x 6 speakers offer better surface area - roughly 24 square inches versus 9.6 for the 3.5 inch rounds. More cone area means better mid-bass response around 80-200 Hz. But dashboard placement limits bass anyway due to distance from your ears and... well, dashboards just resonate differently. Focus your upgrade budget on door speakers first. The smaller dashboard speakers might actually integrate better with aftermarket door components since they won't compete as much in the midrange.
