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 CXA300.1 puts the thunder in your bass. This Class-D 2-ohm stable single channel amp is built to handle 300 watts at 2 ohms for 1 channel, or 150 watts at 4 ohms.

Like most of the amps in the CX series, it's easy to control your bass output from the driver's seat. Pick up a Kicker CXARC wired remote bass level control, plug it in, and optimize your sound easily.

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.

Pretty Good for the Price

The following review is for 46CXA4001T, which is a part of the bundle you are viewing.

Overall, the amp is super solid and seems to be built rather well. Having a rated power certificate in the box was also helpful to see that it actually is putting out the claimed RMS power or above. Currently using it to power a single CompR 12" and it hits hard with the gain barely over 1/3 and no bass boost. Only complaint is that the power and ground inputs are not designed for bare wire, you'll need to buy a U or spade connector to reliably attach your power and ground.

Kicker amp

The following review is for 46CXA4001T, which is a part of the bundle you are viewing.

This is my first kicker amp and love this product and was easy to hook up. I have had other amps and wasn't satisfied on how you had to hook the amp up because the controls you had to use an Allen wrench to loosen or tighten the controls. Kickers product a flat head or a Phillips screwdriver will work on their amps to hook it up and made it easy and fast to hook up! I would recommend this product to anyone else for a small amp that just brings the power to your subwoofer!

Under rated quality amp for the price

The following review is for 46CXA4001T, which is a part of the bundle you are viewing.

This cx 400 is amazing! On the higher end of resistance its minimal, push a c10 or c12 but bump it down and let it go to work. 2 c10's at 300 at 2 ohm, you'll feel it knock, drop it to 1 ohm, good god, I set the sensitivity to run 500 rms, per the rated rms of 533w on kickers birth certificate, this little guy moves single p3d2-12, pounding so hard my rear view mirror shakes to the point you can it rattling the windshield. I recommend this to anyone who wants a lower total rms output or a bi-amp system (given youb match up your impedance and wattage (rms) of chosen sub. I messed up my original purchase, got a JL 12W0 crank it up and live loud

Shipped from the manufacturer in a timely manner, took 3 days instead of the proposed 2 day guarantee, but overall still a great transaction.

Small and powerful

The following review is for 46CXA4001T, which is a part of the bundle you are viewing.

This amp is great. I have it mounted behind the backseat and it takes no room at all. It's got pre-amp and output RCA connections so I have my stereo amp getting signal. You can only use fork terminals with the connections but the connections are solid. Unlike some amps. Two speaker outputs for easier wiring if you are using 1ohm which I have two 10" Kicker DVC 4 ohm subs running at. Overall 5 out of 5 would buy again.

High Quality Amp at a Great Price

This amp is a great match for a Kicker CompR CWR104 (43CWR10). The certificate that came with my amp says it is certified for 329W RMS and it powers the sub perfectly at 2 ohms. I'm impressed with its power rating because it is such a small amp. The Hi-Lo Input Level is a nice feature as I am using the Kicker KISL converter to get signal from the factory speaker wires. The remote bass is another great feature as I am using the Kicker CXARC Remote Control Bass Knob. It's very nice to be able to adjust the bass on the fly depending on what I am listening to. I highly recommend this amp for its quality and RMS power, especially for the price. Nothing but the best from Kicker...
