Kicker DXA 250.4 Car Amplifier User Manual

The DXA amplifi er has dual input sensitivity differential RCA inputs which will receive either high or low level
signals from your car stereo’s source unit. A high-level signal can be run from the source unit’s speaker outputs
to the stereo RCA input on the end panel of the amplifi er using the KICKER KISL as shown (make sure you set
the DXA amplifi er’s input level switch to “HI”). Alternatively, the signal can be delivered to the amplifi er using the
low-level RCA outputs on the source unit. Set the input level switch on the end panel of the amplifi er to “LO”.
Keep the audio signal cable away from factory wiring harnesses and other power wiring. If you need to cross this
wiring, cross it at a 90 degree angle.
Install a fuse within 18” (45cm) of the battery and in-line with the power cable connected to your amplifi er. If you
ever need to remove the amplifi er from the vehicle after it has been installed, the ground wire should be the last
wire disconnected from the amplifi er--just the opposite as when you installed it.
