Scion xA Speaker FAQ

What speakers should I upgrade first in my Scion xA?

Replace the front 6.5-inch speakers first. They handle most vocals and midrange frequencies that you'll notice immediately. The front door panel coaxials or components typically run around 50-60 watts RMS and 4-ohm impedance. Your xA's factory speakers probably sound muddy around 200-800 Hz range. Upgrading front speakers gives you the biggest bang for your buck since they're doing the heavy lifting for music reproduction.

Can I install component speakers in all locations of my Scion xA?

Yes, but focus on the fronts first. The front door panels already have separate 1-inch tweeters, so components make sense there. You'd bypass the factory tweeter and use the component crossover. Rear 6.5-inch locations can accept components too, though many people just run coaxials back there. Component systems typically need 75-100 watts to really shine. The xA's rear door panels might need some modification for tweeter mounting depending on your component set.

What's the difference between coaxial and component speakers for my Scion xA?

Coaxials have the tweeter built into the woofer - simpler install, one piece. Components separate the tweeter and woofer with an external crossover. Your Scion xA already has factory tweeters in the front, so components let you upgrade everything properly. Coaxials work fine for rears since imaging isn't as critical back there. Components usually sound clearer but cost more and take longer to install. The frequency separation is typically better around 3-4 kHz with components.

Will 6.5-inch full-range speakers work in my Scion xA rear doors?

They'll fit, but full-range speakers try to do everything in one driver. The xA's rear door panels can accommodate them physically. Full-range typically means they attempt to reproduce from around 80 Hz up to 15 kHz or so. Problem is they often sound harsh in the upper frequencies since the same cone is handling bass and treble. You might be better off with quality coaxials that have a separate tweeter, even for the rears. The power handling is usually similar - around 60-80 watts RMS.

How do I know if my Scion xA speakers are 4-ohm or 8-ohm?

Factory speakers are almost certainly 4-ohm. Check the back of an existing speaker if you're unsure - it should be marked. Your head unit expects 4-ohm loads, so stick with that impedance when replacing. 8-ohm speakers will play quieter and might not get enough power. Some aftermarket speakers are dual voice coil with different wiring options, but single 4-ohm is safest for the xA. The factory amp (if equipped) is designed around 4-ohm speakers too.
