Plymouth Colt Speaker FAQ

Should I replace the front door speakers or rear deck speakers first in my Plymouth Colt?

Replace the 6.75-inch front door speakers first. These handle most of your vocals and midrange frequencies - around 80-5000 Hz typically. The front stage creates the primary soundscape you hear while driving. Door speakers also get better power delivery, usually 15-25 watts RMS compared to rear deck positioning. Your Plymouth Colt's front doors provide decent mounting depth for component upgrades too. Rear deck can wait since it mainly fills in ambient sound.

What's the difference between coaxial and component speakers for my Plymouth Colt's front doors?

Coaxials put the tweeter and woofer in one unit - simpler install, around 90-20000 Hz response. Components separate them completely. You get a dedicated tweeter (2000-20000 Hz), woofer (40-4000 Hz), and crossover network. Component systems might deliver better imaging in your Plymouth Colt since you can position the tweeter optimally. But coaxials work fine if you're not chasing audiophile-level staging. Components typically need more power though - 25-60 watts RMS versus 15-40 watts for coaxials.

Can I put 6x9 speakers in the rear deck instead of the 5.25-inch ones?

Depends on your Plymouth Colt's model year and available space. The 6x9 format appeared in rear door panels for 1993-1994 models, not rear deck. Deck mounting typically stays at 5.25-inch due to clearance issues with the trunk lid mechanism. 6x9s push more bass - often down to 35-40 Hz compared to 60-80 Hz from 5.25s. But fitting them requires custom work... cutting, brackets, maybe rewiring. Might not be worth the hassle when front upgrades give you more impact.

Are the 4-inch dashboard speakers worth upgrading in my Plymouth Colt?

Probably last priority honestly. Dashboard 4-inch speakers handle treble fill and some upper midrange - roughly 200-15000 Hz. They're positioned well for imaging but limited by size constraints. Maybe 10-20 watts maximum before distortion kicks in. Your Plymouth Colt's dash speakers supplement the main front stage rather than drive it. Focus budget on front doors first, then rears if you want more surround effect. Dash upgrades show subtle improvements... better clarity on vocals, slightly wider soundstage. But you'll notice door speaker changes immediately.

What impedance should I look for when replacing Plymouth Colt speakers?

Stick with 4-ohm speakers generally. Most Plymouth Colt factory systems expect 4-ohm loads - that's what the amplifier section was designed around. Using 8-ohm speakers cuts your power roughly in half... so 20 watts becomes 10 watts. 2-ohm speakers might seem tempting for more power but could overheat your head unit. Some aftermarket speakers run 6-ohm nominal which usually works fine. Just avoid dramatic impedance mismatches that stress the amplifier circuitry or reduce output significantly.
