Pontiac 6000 Speaker FAQ

What speakers should I replace first in my Pontiac 6000 for better sound quality?

Replace the 6 x 9 inch rear deck speakers first. These handle most of your bass and midrange output. The rear deck location typically gets 15-25 watts RMS from your factory amplifier, so look for speakers rated around 30-50 watts RMS with 4-ohm impedance. Coaxial or triaxial options work well here - triaxial adds a small tweeter for highs around 10kHz+. The dashboard 4 x 6 inch speakers mainly fill in vocals and treble, but they're secondary to overall sound improvement. Check your new rear speakers first... if the sound balance feels right, you might not need to touch the dash units.

Can I install component speakers in the Pontiac 6000 rear deck?

Component speakers could work but it's tricky. The rear deck lid was designed for full-range coaxial speakers - you'd need to mount the tweeter separately, probably in the rear package shelf area. Most people stick with quality coaxial or triaxial 6 x 9 speakers instead. Look for models with silk dome tweeters rather than piezo types... much smoother response in the 3-8kHz range where your Pontiac 6000 interior tends to get harsh. The factory mounting depth is usually around 3-4 inches, so measure before buying. Component setups need crossovers too, and finding clean mounting spots in an older car gets complicated.

Why do the dashboard speakers in my Pontiac 6000 sound muffled?

Dashboard 4 x 6 speakers often get choked by the factory grille design and limited airspace. The mounting depth is shallow - maybe 2 inches max - which restricts cone movement below 150Hz. Plus, dashboard placement naturally emphasizes midrange around 1-3kHz where road noise peaks. Try speakers with treated paper cones or polypropylene instead of cheap mylar. The impedance should stay at 4 ohms to match your factory wiring. Sometimes the issue isn't the speakers though... check if the dashboard vents are partially blocked or if the speaker wire connections got loose over time in your Pontiac 6000.

What's the difference between coaxial and triaxial speakers for the Pontiac 6000?

Coaxial speakers have a woofer with one tweeter mounted in the center. Triaxial adds a second smaller tweeter or super-tweeter. For the 6 x 9 rear position, triaxial might give you slightly better treble extension above 12kHz, but the difference is often subtle in a car environment. The 4 x 6 dashboard location works fine with basic coaxial - you're mainly filling in midrange anyway. Quality matters more than the number of drivers... a good coaxial with proper crossover design usually beats a cheap triaxial. Both types should handle 20-40 watts RMS comfortably in your Pontiac 6000's factory setup.
