About the Ground Zero GZTC 165.3X-ACT
From our tech experts at CEN
Ground Zero 6.5 inch component speakers, with separate tweeters for mounting where you will actually hear them, rated at 150w RMS.
Who it suits
Drivers building a proper front stage and happy for tweeters to be mounted separately, which usually means a professional fit.
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: Can the GZTC 165.3X-ACT run from a head unit?
A: It is designed for active use, so each driver is fed from its own amplifier channel with the crossover set by an active processor or amplifier at the recommended 430 Hz and 6000 Hz points, rather than run directly from a head unit.
Q: What crossover frequencies should I use with the GZTC 165.3X-ACT?
A: Ground Zero recommends 430 Hz between the midwoofer and midrange, and 6000 Hz between the midrange and tweeter.
Q: How much space do the GZTC 165.3X-ACT drivers need?
A: The midwoofer needs a 142.5 mm mounting diameter and 68 mm depth, and the midrange a 94 mm mounting diameter and 32 mm depth.
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.
