Mount a Kicker CX amp vertically to save space

The CX Series spans all kinds of systems, whether you're just trying to get a little more out of your factory radio or you're ready to blow the doors off with a completely aftermarket setup. Either way, the quality of your sound is at the heart of the CX Series. Sleek, simple styling and installation flexibility all round out the amplifiers' functionality.

Kicker makes your installation simple, but gives you plenty of options. Make it easy on yourself when plugging in with Kicker's KISL so you can take high-level signal from the headunit's speaker outputs straight into the amp's RCA input. Also, most models are just more than two inches thick and included brackets allow you to install these vertically. If space is at a premium in your ride, the CX series gives off plenty of power while saving you some room.


The CXA300.4 will make sure your cabin speakers have all the power they need. This Class-D 2-ohm stable 4-channel amp is built to handle 75 watts at 2 ohms for 4 channels, 40 watts at 4 ohms on 4 channcels, or 150 watts at 4 ohms for 2 channels when bridged, and the subwoofer channel can pump out 300 watts at 2 ohms.

With a total power output at 600 watts, 3-way protection circuitry and a pulse width modulated power supply, the CXA300.4 will power your speakers for the long haul.

Under the hood

The CX Series has a lot of built-in technology to make sure your system just keeps going for the long haul. With litz-wound transformers to maximize power transfer while minimizing power loss, high current switching, buffered RCA outputs, these amps are built to put out lasting, quality power.

These amps also include their own crossovers and an adjustable KickEQ Bass Boost. A 3-second turn-on delay helps eliminate any additional interference that might affect your system.

Power a sub or a whole system with Kicker CX amps

But these amps also have Kicker's Failsafe Integration Technology inside. That means they can take signal from any audio source and run it straight into the amp. For you, it means no need for line-out converters, step down modules, processors or less conventional wiring to complete your system. Kicker's FIT eliminated the need for additional equipment that could introduce additional noise to your signal. It even works well with factory amplified systems from other premium brands.

For a potent, versatile power solution for your sound system, pick up as many CX Series amps as you need here at Sonic Electronix. Add one, or however many you need, to your cart today.

Great amp

The following review is for 46CXA3604T, which is a part of the bundle you are viewing.

Been wanting to try out some Kicker products for a while. Planned to just add a sub, but decided to add more power for the other 4 speakers as well. Great sound, and plenty of power on tap for my small extended cab truck.
