Kicker CXA400.1 (46CXA4001T)

This CX-Series Mono Amp is now one-ohm stable, giving you even more power and wiring options for your system! This Class-D CXA400.1 features a variable bass boost with KickEQ, giving you as much as a 6dB of extra bump. A powerful 12dB crossover and 24dB subsonic filter is included, letting you quickly tune your system to perfection. Use the full-range outputs to expand your system with other bass amps, or a full-range amp to complete your system. CX.1 Amplifiers accept up to 40 volts (400 watts) of speaker-level input signal. This kind of flexibility both makes line-out converters unnecessary and optimizes your sound quality at the same time!

Pretty Good for the Price

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.

Small and powerful

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.

Great transaction

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

Under rated quality amp for the price

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

Kicker amp

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!
