Chrysler Newport Speaker FAQ

What speakers should I replace first in my Chrysler Newport?

Replace the 6 x 9 rear speakers first. They handle most of your music's frequency range and deliver the biggest sound improvement for your money. The dashboard 3.5 inch speakers mainly cover mid-range frequencies around 500-4000 Hz, but the rear speakers do the heavy lifting from about 80 Hz up to 15 kHz. Your Newport's rear location typically gets 15-25 watts per channel from the factory head unit. Start there, then consider the dash speakers if you want clearer vocals.

Can I install component speakers in the rear of my Chrysler Newport?

Yes, the rear location accepts component speakers, though you'll need to plan your tweeter placement. Component speakers separate the woofer and tweeter - the 6 x 9 woofer handles bass and midrange while a separate tweeter covers highs above 3-4 kHz. Most aftermarket component sets come with crossovers rated around 12 dB per octave. Mount tweeters in the rear deck or door panels if possible. The Newport's rear speaker opening should accommodate most 6 x 9 component woofers without major modifications. Coaxial speakers might be easier though - they combine everything in one unit.

What impedance should I look for in Chrysler Newport replacement speakers?

Stick with 4-ohm speakers for both locations. Most factory Newport systems expect 4-ohm loads, and using 8-ohm speakers will reduce your power output significantly. Your head unit probably delivers around 15-20 watts RMS per channel into 4 ohms, but only 8-12 watts into 8 ohms. The 6 x 9 rear speakers can typically handle 30-50 watts RMS, while the 3.5 inch dash speakers usually max out around 15-25 watts RMS. Don't worry too much about underpowering - it's better to have clean power than distorted high wattage.

Why are my new 6 x 9 speakers not fitting properly in my Chrysler Newport?

Check the mounting depth first. Newport rear speaker locations might have limited clearance behind the mounting surface. Most 6 x 9 speakers need 2.5-3.5 inches of depth, but some aftermarket units are deeper than factory specs. The screw hole pattern could also be different - factory speakers often use proprietary mounting points. You might need speaker adapter plates or brackets. Also verify you're not hitting the rear window or deck lid mechanisms. Measure twice before ordering - the opening size and the mounting depth are different things entirely.
