AMPLIFIER: Kickers DXA250.4 features separate controls for the front and rear channels so it can work with a variety of different speakers or subs. High-pass filters clear out rumble from small speakers so they can play more efficiently, while low-pass filters adjust the frequencies going to your subs, so they'll play bass cleanly. Bass boosts on the front and rear channels. The DXA250.4 4-channel amplifier can send 30 watts RMS to each of your front and rear speakers from a compact chassis that'll fit into a lot of places in your vehicle. This amp delivers around three times the power of a typical factory radio, so it'll add a lot of clarity and punch to your music. You can also use the front channels on the DXA250.4 to power your front speakers, and bridge the rear channels together to power a subwoofer with 125 watts RMS.
