Subaru Impreza Speaker FAQ

What speaker sizes fit in a Subaru Impreza and which locations should I upgrade first?

Front door panels get priority - they handle most vocals and mid-range frequencies. Most Subaru Impreza models use 6.5 inch speakers in both front and rear positions, though 2017 models switched to 6 x 9 inch fronts. Start with the fronts since they're positioned closer to your ears. The rears mostly fill in ambient sound and bass support. You'll want speakers rated around 50-75 watts RMS with 4-ohm impedance to match factory wiring. Component speakers typically outperform coaxials in the front positions because the separate tweeter placement improves imaging.

Should I install coaxial or component speakers in my Subaru Impreza?

Component speakers work better in front locations if your Subaru Impreza has tweeter mounting points in the A-pillars or door panels. The separate woofer and tweeter design creates better stereo imaging - frequencies seem to come from the right places. Coaxials might be simpler for rear positions since soundstage isn't as critical back there. Components need crossovers though, which means finding mounting space and possibly running additional wires. If you're keeping the factory head unit, coaxials could be easier to drive since they don't split power between components. Check if your doors have enough depth for 6.5 inch drivers - some need spacer rings.

What's the difference between full-range and other speaker types for Subaru Impreza rear positions?

Full-range speakers try to reproduce everything from around 80Hz to 20kHz without a separate tweeter. They're basically coaxials without the dedicated tweeter cone on top. For Subaru Impreza rear positions, full-range speakers can work since you're mainly filling in ambient sound rather than creating primary soundstage. The frequency response usually isn't as smooth as proper coaxials or components. But they're often cheaper and easier to install. Power handling tends to be lower - maybe 30-50 watts RMS versus 60-80 watts for quality coaxials. If your rear doors don't have much space or if you're on a budget, full-range speakers might be adequate for background fill.

Why did the 2017 Subaru Impreza change to 6 x 9 inch front speakers?

The 2017 redesign apparently accommodated larger front speakers - 6 x 9 inch versus the traditional 6.5 inch rounds. Oval speakers generally move more air due to increased cone area, which can mean better bass response and higher output levels. The extra surface area helps with lower frequencies that 6.5 inch speakers struggle with. However, round speakers often have better off-axis response since the cone shape is more symmetrical. If you're upgrading a 2017 Subaru Impreza, you'll need 6 x 9 inch speakers for the fronts but can still use 6.5 inch in the rears. Make sure the mounting depth works - some aftermarket 6 x 9 speakers are deeper than factory units.
