    Reliable and dependable

    I purchased this unit to go along with a 10” Kicker subwoofer. It works great! Setup is always a challenge for car audio, but in this case the clear instructions helped make it a straightforward process. The amp is easy to adjust with its frequency and loudness adjustments. I have had this unit installed in my 1979 Toyota Corolla a while now and it has never let me down. It provides plenty of power to the subwoofer and allows me to feel the thump of the bass as I drive - even over a loud exhaust system.

    Kicker amp and sub

    I had this amp installed the other day with the 12’ down firing sub from Kicker. It sounds amazing and delivers great bass. The amp was installed under my front passenger seat and you can’t even notice it’s there. There is a big difference from hearing the demo audio system in the store than from hearing it in my car. I 100% recommend

    Great amp for tight space.

    Great amp to drive a single 10 woofer (massive audio shallow mount). Have this in a Tacoma for my daughter and it sounds great! Its compact in size to fit under a bench seat in a standard cab without compromise to power. Highly recommend.

    Awesome little amp!

    Kicker has been a great brand for decades and are still on it. This little amp pushes my bridged SVC 12" sub easily. I haven't tried it with a DVC and don't really feel the need to. For my application this amp is perfect! It's small (to fit in the recess in my trunk) and powerful. Do yourself a service and get this one instead of a cheapo. You won't regret it.

Questions & Answers

  • I have one JL 12 in. w3v3-4 subwoofer in a ported box. how well will this amp work with this sub? thanks you for your help.

    According to the JL Audio website, "the JL 12W3v3-4 is best used with amplifier power in the 150W - 500W range" and their power meter shows that optimum power would be about 250 watts RMS. The KICKER CXA400.1 amplifier will produce 150 watts RMS when connected to a single 4-ohm load speaker as you specified. If you are looking for great sound and performance without maximum SPL (loudness), the CXA400.1 will work fine. If you desire more SPL with the single 4-ohm speaker load you currently have, you may be better suited to use a KICKER CXA800.1 instead as it will provide 300 watts RMS in to a 4-ohm load. If you have further questions, please feel free to reach out to KICKER Technical Support. Email: support@kicker.com Phone: 405-624-8510, Mon-Fri, 8:00-5:00 Central time.
