Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Door treatment matters as much as the speaker, and these repay an amplifier. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs.

Frequently Asked Questions
Q: How do I choose the right amplifier for my speakers or subwoofer?
A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.
Q: What cutout and depth does the GZIF 5.2 need?
A: The GZIF 5.2 needs a 117.5 mm (4.63 inch) mounting diameter and 56 mm (2.20 inch) of mounting depth.
Q: How much power can the GZIF 5.2 handle?
A: It is rated at 70W RMS and 110W max at 4 ohms, with 90 dB efficiency, so it runs from a head unit or a small amplifier.
Q: Can CEN fit these speakers for me?
