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 is the mounting depth of the GZIF 6501FX?
A: It needs 44 mm (1.73 inch) of mounting depth and a 142.5 mm (5.61 inch) cutout.
Q: Will the GZIF 6501FX run from my head unit?
A: Yes. It is a 4 ohm speaker with 91 dB efficiency, so it works from a head unit. It can also take up to 70W RMS from an amplifier.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
