Buick Reatta Speaker FAQ
What speakers should I replace first in my Buick Reatta for the biggest sound improvement?
Replace the dashboard 4 inch speakers first. These handle most vocals and midrange frequencies - around 200Hz to 4kHz where your ear is most sensitive. The factory coaxials in the dash probably have deteriorated foam surrounds after 30+ years. You'll notice clearer dialogue and instrument separation immediately. The rear speakers can wait since they mainly provide fill and bass support.
Can I install component speakers in the rear location of my Buick Reatta?
Depends on your model year. 1990-1991 Buick Reatta models came with component speaker capability in the rear 6.5 inch locations. Earlier models had 6x9 coaxials in the deck lid. You'd need to verify crossover mounting space and tweeter placement options. Component systems typically offer better imaging but require more installation work. Most people stick with quality coaxials unless they're doing a full audio rebuild.
What's the difference between the rear speaker setups in early vs late Buick Reatta models?
1988-1989 models used 6x9 speakers mounted in the rear deck lid - these could be coaxial, full-range, or triaxial types. Starting in 1990, Buick Reatta switched to 6.5 inch rear speakers with coaxial or component options. The 6x9 setup typically provides more bass response due to larger cone area. But the 6.5 inch speakers might image better since they're closer to round. Check your specific mounting points before ordering replacements.
How much power do the dashboard speakers in a Buick Reatta typically handle?
Most 4 inch aftermarket speakers handle 20-50 watts RMS, which should be plenty for dashboard mounting in the Buick Reatta. Factory head units usually put out 8-15 watts per channel. The small enclosure behind the dash limits bass response anyway - you're mainly looking for clear mids and highs. Focus on sensitivity rating over power handling. Something around 88-92 dB sensitivity will sound noticeably louder than factory speakers.
Should I go with triaxial speakers for the rear deck of my 1988 Buick Reatta?
Triaxial speakers add a super tweeter to handle frequencies above 10kHz. Whether this helps depends on your listening preferences and the rest of your system. The extra tweeter might make things sound brighter, but it could also create harshness if your dashboard speakers are already bright. A quality 2-way coaxial often sounds more balanced. Test different options if possible - triaxials work better for some music genres than others.
