Oldsmobile Silhouette Speaker FAQ

What speaker sizes work in my Oldsmobile Silhouette's rear door panels?

6.5 inch speakers fit the rear door panels. You can install coaxial, component, or full-range types - basically any 6.5" speaker will work. The mounting depth might vary between aftermarket brands, so measure your available space first. Around 2.5 inches of clearance should handle most speakers.

Should I upgrade the dashboard speakers or door speakers first in my Oldsmobile Silhouette?

Start with the 6.5 inch door speakers. They handle more power and produce better bass response than the 4 inch dashboard units. Door speakers typically run 15-60 watts RMS while dashboard speakers max out around 20-30 watts. The larger cone area means you'll notice the improvement immediately. Dashboard speakers mostly fill in the high frequencies anyway.

Can I put component speakers in all locations of my Oldsmobile Silhouette?

Depends on your model range. The dashboard spots only accept coaxial or full-range speakers - no components there. Door panels work with components though, and that's where you want them. Separate tweeters in the doors create better stereo imaging than dashboard-mounted ones. You'll need to find tweeter mounting spots or use the existing locations if your Silhouette already has them.

What's the impedance rating for Oldsmobile Silhouette factory speakers?

Most likely 4 ohms, though some factory setups used 8 ohm speakers. Check your existing speakers for markings before ordering replacements. Modern aftermarket speakers are typically 4 ohms anyway. If you're adding an amplifier, 4 ohm speakers will draw more power and play louder. Your head unit should handle either impedance without issues.

Do the front and rear 6.5 inch speakers in my Oldsmobile Silhouette use the same mounting?

Generally yes, but verify the mounting depth. Front door panels sometimes have different clearance than rear doors. The bolt pattern should be standard 6.5 inch spacing. Some aftermarket speakers come with multiple mounting rings to handle variations. Measure twice, especially if you're going with deeper speakers that need more clearance behind the panel.

What frequency range should I look for in Oldsmobile Silhouette replacement speakers?

For 6.5 inch speakers, look for 50Hz-20kHz response. The 4 inch dashboard speakers won't go as low - maybe 80Hz-18kHz. Don't get too caught up in the numbers though. Real-world performance depends more on build quality and power handling. Focus on RMS wattage ratings between 20-75 watts for the 6.5" speakers, 15-40 watts for the 4" units.
