Infiniti Q70 Speaker FAQ

Should I replace front or rear speakers first in my Infiniti Q70?

Start with the front door panel speakers. They handle most of your music's midrange and vocal frequencies, so you'll notice the biggest improvement there first. The front 6.5-inch or 6 x 9-inch speakers (depending on your Q70's configuration) carry about 70% of what you actually hear while driving. Rear speakers mostly fill in ambient sound and bass support. If budget's tight, just do the fronts - you might be surprised how much better everything sounds without touching the rears.

What's the difference between coaxial and component speakers for the Infiniti Q70?

Coaxial speakers put the tweeter and woofer in one unit - easier install, decent sound. Component speakers separate them, giving you more control over placement and typically better sound staging. For the Q70's front door panels, components might be worth it since you can mount tweeters higher up near the A-pillar. The rear doors? Coaxials probably make more sense unless you're going for a full custom setup. Power handling usually runs 20-100 watts RMS for most aftermarket options in these sizes.

Why does my Infiniti Q70 have different speaker sizes between model years?

The door panel design changed between 2015 and 2016. Earlier Q70s used 6 x 9-inch speakers front and rear, while 2016-2017 models switched to 6.5-inch rounds. The 6 x 9s give you more cone area - better for bass response and overall volume. But 6.5-inch speakers often have better imaging and clearer mids. Both sizes handle similar power ranges, usually 4-ohm impedance. Check your door carefully though... some installations might have been modified from factory specs.

Can I install component speakers in all four locations on my Infiniti Q70?

Technically yes, but it gets complicated. The front door panels have decent tweeter mounting options, but the rear doors might need custom work. You'd need crossovers for each pair - that's four crossovers total to mount somewhere. Power requirements jump too, probably need 50-75 watts RMS per channel minimum to drive components properly. Most people run components in front, coaxials in rear. Keeps the install cleaner and the sound balance more predictable.

What power rating should I look for in Infiniti Q70 replacement speakers?

Aim for 25-60 watts RMS handling for daily driving. The factory system probably pushes 15-25 watts per channel, so anything in that 40-80 watt range gives you headroom without going overboard. Peak power ratings are mostly marketing - focus on RMS. Higher sensitivity ratings (90dB+) matter more than raw power handling in the Q70. The cabin size means you don't need massive wattage to get loud. Just make sure your speakers can handle whatever amp power you're planning.
