You could also use this amp to drive a pair of high-performance speakers or components with 180 watts RMS each from bridged channels, and the sub with 300 watts.

Tone controls for the best sound

Separate high-pass filters on the front and rear channels help you sculpt the sound to get the most out of your speakers. A variable low-pass and a fixed subsonic filter help you tune the bass for your sub, enclosure, and vehicle, while a variable bass boost allows you to add some low-end punch. An optional wired remote lets you conveniently adjust the subwoofer level from your front seat.

Hooks in almost anywhere in almost any position

Kicker's Fail-Safe Integration Technology (FIT™) keeps this amp's input free from noise or interference, so you can tap into your speaker wires for a signal without a worry. A 3-second turn-on/turn-off delay eliminates system pops and other noises. The CXA660.5T comes with hardware that lets you mount it vertically, so you can put it in a location that takes up very little floor space and looks cool too.

Product Research

Features

Overview: The CXA 660.5 5-channel amplifier is effectively three amps built into one chassis, two full range 2-channel amps labeled Amp 1 and Amp 2, and a mono amp labeled Sub. Each pair of full range channels is bridgeable, so it can be wired as 5-channel, 4-channel, or 3-channel. Kicker uses a Class A/B design for the full range channels and Class D for the subwoofer channel.

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output. The criteria for measuring amplifier power uses a DC input voltage of 14.4 volts and the RMS power output is measured over a frequency range of 20 Hz to 20 kHz (for full range amplifiers), with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples).

CEA-2006 Specifications:

  • Power Output:
    • Full Range Channels: 65 watts RMS x 4 into 4Ω
    • Subwoofer Channel: 150 watts RMS x 1 into 4Ω (25-200 Hz)
  • Signal to Noise Ratio: 75 dBA (measured at 1 watt into 4Ω)

Other Specifications:

  • Power Output:
    • Full Range Channels:
      • 2Ω: 90 watts RMS x 4 (14.4 volts, =1.0% THD+N)
      • Bridged (4Ω): 180 watts RMS x 2 (14.4 volts, =1.0% THD+N)
    • Subwoofer Channel:
      • 2Ω: 300 watts RMS x 1 (14.4 volts, =1.5% THD+N)
  • Signal to Noise Ratio: 90 dB (at rated power output)

Controls:

  • Input Level: 2-position switch; select high (speaker-level) or low (line-level)
  • Input Gain Control: independent rotary gain controls for the front (Amp 1), rear (Amp 2), and Sub channels; continuously variable from 250mV to 10V with the input level switch set to low; 1V to 40V with the input level switch set to high
  • Crossovers: separate crossover controls for the front, rear, and sub channels; front and rear rotary controls range from Off to 200 Hz (high pass); sub rotary control from 50Hz to 200Hz (low pass); the slope is 12 dB/octave for all three
  • Fader: 2-position switch; turn on when using dedicated front and rear inputs; leave off when only using one pair of inputs
  • Sub Input: 2-position switch; Sub when using a dedicated subwoofer input, Amp 2 without a subwoofer input
  • KickEQ Bass Boost: increase the subwoofer channel bass level between 0dB and +6dB via the rotary control; centered at 40Hz

Subsonic Filter: The amplifier's sub channel features a non-defeatable 25Hz Subsonic Filter with a 24dB/octave slope. The Subsonic Filter rolls off extremely low frequencies that can't be cleanly reproduced by the amplifier and subwoofers. This reduces distortion and helps the amp run more efficiently.

Mounting: The CX Series amplifiers can be mounted vertically, if desired, with the included mounting brackets. When mounted vertically, the dimensions are:

  • Height: 6.75"
  • Length: 14.125"
  • Width: 2.375"

Auto Turn-on: The amplifier has two methods of turning on: +12V and DC Offset. The preferred method is to run an 18-gauge wire from the remote turn-on lead of the source unit to the Remote (REM) terminal on the amp. When a +12V signal is detected on the wire, the amplifier will turn on. If your source unit lacks a remote turn-on lead (a factory head unit, for example), you can choose to turn on the amplifier via the DC Offset method. When a DC offset is detected (>2.5 volts) on the speaker-level inputs, the amplifier automatically turns on.

Wire Connections: The CXA660.5 has set screw terminals for power, ground, and turn-on lead (REM). The power and ground terminals will accept up to 4-gauge wire (recommended), and the turn-on lead will accept up to 8-gauge (18-gauge recommended). The set screws are loosened/tightened with the supplied 3mm Allen wrench. The speaker outputs are slotted, screw-down terminals, which will accommodate bare wire or spade connectors. The speaker slots are 0.335" wide.

External Fuse: The amplifier does not include a built-in fuse, therefore an external fuse should be placed on the power wire, within 18" of the battery. It is recommended that a 4-gauge amplifier wiring kit and an 80-amp external fuse be used when installing the amplifier.

Input Signal: The CXA660.5 accepts either high (speaker-level) or low (line-level) input signals on the three pair of RCA inputs (Amp 1, Amp 2, Sub), selectable using the input level switch on the end of the amp. When using a speaker-level input signal, add the optional Kicker KiSL speaker-level to RCA adapter. The input sensitivity is 250mV-10V (low) or 1V-40V (high).

Optional Wired Remote: The optional CXARC wired remote can be added to remotely control the subwoofer channel output level of the amplifier. The CXARC's control knob can be mounted near the driver's seat, and the control's cable extended to the amplifier location.

Certified Power: Each amplifier is tested when it comes off of the assembly line. Tests are run for Total Harmonic Distortion, Signal-to-Noise Ratio, Protection Circuit, and Total Power Output. A Certified Power certificate with model and serial number is included with each amp with the measured power output figure, and a pass/fail grade for the other tests.

Customer Q&A

Q
Using this amp with hi-level inputs in a Tacoma. The front channels off the stock HU give around 12V and the rear channels give around 8V. I am using front channels for amp1 inputs that power the door speakers (this works great and the sound is excellent). The rear channel is the input for the sub amp and it works, but it is not very loud. I have to have the gain all the way up on the sub amp and the bass boost up a lot too. I also have a remote bass knob on this amp too. The bass is there, but it just seems to not be as loud as the amp1 output. The subwoofer I'm using is the Kicker 48CWRT104 at 2 ohm. My door speakers are the Kicker 46CSC6934 and Kicker 46CSC674 also at 2 ohm. Could this issue be caused by the low voltage of the rear channel input from my stock HU that is causing the low volume on the sub? Also, the manual says you can run the outputs of the amp from one input, but does that include the sub amp output? So if I used only the amp1 input, would my sub amp be able to use that input as well?

Q
Will this work with a 2004 4runner with JBL factory head unit? I have already upgraded the front and rear speakers to kicker 4ohm front and back and am running a 8in kicker sub.

This sweet Kicker 46CXA660.5t CX series 5-channel amp is a great choice Pierson. This amp does have a speaker level input capability when using a pair of the Kicker speaker-level to RCA adapters, so you could replace your existing JBL amp with this Kicker for a massive improvement. This would not perform any processing on your factory JBL radio however, to do that you would need to add something like this Audiocontrol LC7i in the link below. This connects to your factory system and processes and restores bass before the signal gets passed to the Kicker, this can make the entire setup sound better. I'll shoot you an email with the amp, wiring, and processor for safekeeping! https://www.crutchfield.com/p_161LC7IB/AudioControl-LC7i-Black.html

Q
Can you run 4 speakers at 4 OHMS and 1 sub at 2 OHMS at the same time or do it all have to be on the same level of OHM?
[ spencer  May 23, 2022 ]
1 answer
A
Thank you for reaching out to us and that is a great question! You can absolutely run your full range speakers at 4 ohms and run the subwoofer at a different ohm load at the same time without any problems.

Q
Is this compatible with a Kenwood radio system that was added to my 1994 Chevy Blazer about a year ago?
[ Hayes  Apr 21, 2022 ]
3 answers
A
If your Kenwood radio has a sub out line in the rear of your radio and yes this set up is compatible with your Head unit. With the sub out line in your head unit you would just need to install the amp to power, acc and the sub out line from the head unit. Without the sub outline in your head unit you will need to split off your existing speaker to this amp and back to the speaker.

If you added the Kicker 46CXA600.5T, it will completely under drive the sub. You will need an amp with at least 500+ watts to keep up with the high/mids from a 65watt rms 4 channel system. Underpower = distortion
[ BRETT  Apr 21, 2022 ]
A
This sub is useable with any amp worthy of the power the sub can supply. It's never bad to have more amp than sub to minimize distortion the amp can cause by pushing too far. Underpowered amp = distortion The sub will take 1000 watts peak power, 500 watts ish continuous
