Subaru WRX Speaker FAQ
What speakers should I upgrade first in my Subaru WRX for the biggest sound improvement?
Start with the front door panel speakers. Your Subaru WRX front 6.5 inch speakers handle most of the stereo imaging and vocal clarity. The rears mostly fill in ambient sound. Front component speakers around 75-100 watts RMS will give you the most noticeable upgrade. You'll hear clearer highs from separate tweeters and better midrange separation. The rear coaxials can wait unless you're chasing that full surround effect.
Can I mix component and coaxial speakers in my Subaru WRX?
Yes, but it gets tricky with the timing. Components up front, coaxials in back works fine for most setups. The 6.5 inch size stays consistent which helps. Your front components might need 4-8 ohm crossovers depending on the tweeter design. Rear coaxials typically run straight off head unit power. Just watch the frequency overlap around 2-4 kHz where both speaker types might compete. Some people actually prefer this mixed approach for the WRX cabin acoustics.
What's the difference between full-range and coaxial speakers for the rear doors?
Full-range speakers try to reproduce everything from one cone - usually 80 Hz to 20 kHz range. Coaxials add a separate tweeter for better high frequency response above 3-4 kHz. In your Subaru WRX rear position, coaxials probably make more sense. The tweeter helps with soundstage width when you're sitting up front. Full-range might sound slightly more coherent but loses those crisp highs. Both work with factory wiring though. Power handling is usually similar - 50-80 watts RMS for decent aftermarket options.
Do I need an amplifier for 6.5 inch component speakers in my Subaru WRX?
Depends on your expectations and the components you choose. Factory head unit pushes maybe 15-20 watts RMS to each 6.5 inch location. Entry-level components might sound okay with that power. But really good components need 50-100 watts RMS to open up properly. The separate tweeters especially benefit from clean power. Without an amp, you might get improved clarity but miss out on the dynamic range. Check the sensitivity ratings too - 90+ dB components work better with factory power than 85 dB ones.
