What fits a 5.25" door opening
These 5.25-inch coaxial speakers drop into standard factory locations and come as a matched pair. The three-way layout puts woofer, midrange and tweeter on one frame so a single cut-out handles full-range sound. They suit owners who want clearer audio without custom fabrication.
Power handling and frequency limits
Continuous power is rated at 40 watts RMS with a 300-watt peak ceiling, so the pair works well with modest head units or small amplifiers. Frequency response spans 40 Hz to 25,000 Hz at 88 dB sensitivity, giving usable bass extension and extended treble from a single driver assembly.
Cone materials and shallow mounting
A carbon-mica 3D cone woofer, 52 mm poly-ether imide midrange and matching dome tweeter share a ferrite magnet structure and single-roll rubber surround. Mounting depth is only 44 mm, allowing installation behind tight door panels where deeper baskets would foul window mechanisms or trim clips.

Questions about this item
Should I pick the 5.25-inch pair or a different size for my door cutouts?
The CSZX530 is a 5.25-inch pair with a 44-millimetre mounting depth; measure your door aperture and depth to confirm fit.
What does the 300-watt peak figure mean for everyday listening?
The 300-watt peak is a short-term maximum; continuous output is 40 watts RMS, which determines real-world loudness.
How does the 88 dB sensitivity affect amplifier matching?
At 88 dB SPL the speakers need moderate amplifier power to reach high volume; pair with an amp rated near 40 watts RMS per channel.
