46CXA660.5 5-Channel Amplifier
CX Series amps achieve high power through an optimised circuit layout and high-grade internal components. Efficient heat sinks keep temperatures in check, and the optional remote level control lets you adjust bass on the fly.
Five Channels of Fun
The CXA660.5 uses Class A/B technology across four mid/high-range channels and a Class D power plant for the bass channel. FIT+™ (Fail-safe Integration Technology-PLUS) ensures compatibility with nearly every head unit.
KickEQ™ variable bass boost adds up to 6 dB of extra bass with a turn of the knob. A 12 dB crossover and 24 dB subsonic filter let you tune the whole system quickly.

About the Kicker 46CXA6605
From our tech experts at CEN
A 5-channel amplifier, rated at 660w RMS. Enough channels for a front and rear stage, or a front stage with the remaining channels bridged onto a sub.
Who it suits
Drivers who have upgraded their speakers and found the head unit cannot drive them. This is the step that makes good speakers sound like good speakers.
Our tech experts advise
Published power figures mean little until the amplifier is matched to the speakers and the gains are set with a meter rather than by ear. It needs a fused feed from the battery on the correct cable gauge, the part we most often see done badly. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

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 wiring do I need to install this amplifier?
A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.
Q: What class of amplifier is this and does it matter?
A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: Can CEN install this amplifier?
A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
Q: Can the 46CXA660.5 power speakers and a subwoofer at the same time?
A: Yes. It has four full-range channels for door speakers (65W x 4 at 4 ohms, 90W x 4 at 2 ohms) and a dedicated Class D sub channel (150W at 4 ohms, 300W at 2 ohms).
Q: Does the 46CXA660.5 work with a factory head unit?
A: Yes. It accepts speaker-level input signals of up to 40 volts, so a line output converter is not normally needed.
Q: Is there a remote bass control for the 46CXA660.5?
A: Yes. It is compatible with the Kicker CXARC remote bass control, sold separately.
