Are these worth it over my factory speakers?

For most cars, yes. At 91 dB sensitivity they run off a stock head unit, and 70 W RMS gives headroom if you add an amp later.

Do I need an amplifier?

No. The high sensitivity means a factory radio can drive them to reasonable volume. An amp of about 50-70 W per channel gets the most out of them.

Will they fit my car's 6.5-inch openings?

Check mounting depth first: they need about 48 mm. The included multi-fit adapters can be trimmed to match many factory cutouts, but not every vehicle.

Two speakers, two grills, multi-fit installation adapters and tweeter mounts for surface or flush mounting.

When is the price lowest?
