Upgrade to louder deeper bass with our plug and play kicker key amplifier upgrade kit. If you own an Acura sedan from the years 2004 to 2020 it might be possible you are not satisfied with the factory subwoofer output. This plug and play amplifier captures the output of the factory subwoofer and amplifies it with seven times the power resulting in bass that is three times as loud.
This PNP amplifier upgrade relies on the output of the factory amplifier to be in working condition. If the factory subwoofer of your Acura does not work it may be possible that this amplifier will result in no audio. Please make sure your factory subwoofer and amplifier are working before buying.
When installing this amplifier a new power line from the amplifier to the battery is required. Another power line from the fusebox to the amplifier is required. You will also need to secure and ground the amplifier in the trunk(see image for best location). The speaker connections are plug and play. You will not need to wire tap or wire splice and of the factory wiring. The installation is simple, first run the wires to the necessary locations then disconnect the factory subwoofer connection and connect it to the amplifiers t-harness. Then connect the other side of the t harness back to the subwoofer and your upgrade is complete.
When installing this amplifier on the factory radio the amplifier is tuned accordingly and will begin working to its full potential right away. If you are using an aftermarket radio with this amplifier tuning will be required. Also if your aftermarket radio was installed improperly you may need to run a set of RCAs from the amplifier to the back of your aftermarket radio (RCAs are included). This amplifier supports an external bass knob but it does require an additional purchase. On your factory radio the factory subwoofer settings will still control the bass output as normal. On your aftermarket radio the control of the subwoofer will vary by your installation.
