Product Highlights

Description

Authorized dealer

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.

CXA1800.1

The CXA1800.1 puts the thunder in your bass. This Class-D 2-ohm stable single channel amp is built to handle 1800 watts at 2 ohms for 1 channel, or 900 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.

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.

Replacement amp.

The following review is for CXA1800.1, which is a part of the bundle you are viewing.

I bought the Soundstream t6000.1 mono amp first. Got the amp a few days later and ugggg something was wrong. Talked to the team at Sonic Electronix and they got me to send the amp back for testing. Sure thing something was wrong with it. I ended up upgrading to this Kicker CXA1800.1. This amp is a little beast. It is pushing my 2 T5 12" subs like a boss. The amp runs powerful and cool. I am a happy dude. Just want to say thanks to the team at Sonic Electronix. They took care of my problem quick and painlessly. ????????????

I recommend this amp. The one o got was on sale and I believe discontinued but the new one is this and more. The kicker is not playing when they make their products, I paired mine with 2 kickers comp r 12's in the ported factory box. Man, I can't say enough about the quality.

It's great but not a 1800, it's 3600 watts. It should have been, that's what I paid for anyways.

Kicker CXA18001 (43CXA18001)

This is by far the most powerful amplifier I've ever bought...& for good reason, too! I need all 1800 watts to power 2 12" L7S Solo Baric's! And believe me, this amp more than delivers unbelievable chest pounding bass! Had to upgrade all of my power and ground cables but it's been worth it! Highly Highly HIGHLY RECOMMEND THIS AMP!!

Disappointment

I have two 12in Rockford fosgate T1D2's that are 800 rms a peace 1600 total. I bought this app thinking it's enough wattage to run these Subs and it barely moves my subs. I upgraded my alternator and all my wires and with the big three. And it still barely moves them

Ehhhhhhh

Bought this amp cause I’m a kicker fan and wanted to run 2 cvx 10’a at 2 ohm. Amp says it’s 2 ohm stable. Never had the amp over 50% power and it blew in a year. Sounded good while it lasted but didn’t last long. Sonic is always 5 stars in my book. But this amp a solid 3. My opinion anyways.
