Kicker Amp Reviews – KXA400.4
The KXA400.4 model of the Kicker KX Amps will power your car’s speakers 50 watts x 4 at 4 ohms, 100 watts x 4 at 2 ohms, and 200 watts x 2 mono at 4 ohms. It’ll always stay cool because of it’s high-mass heatsink, high-tech components, and Class-D amp technology. If you’re building your system slowly, start your system off with a pair of subs, using the amp 200 watts x 2 until you purchase the rest of the system, then use the amp for your speakers.
You’ll enjoy clean sound with Kicker’s Fail-Safe Integration Technology which protects from any noise or interference your car may make. The KXA400.4’s gains are hidden behind a closing door. You can adjust the high and low pass filters for any kind of speaker, use both filters to create a bandpass.
Kicker has made adjusting your gains a breeze. They have test tones on their website you download and play them in your car while tweaking your amp. Turn the gain up until it’s red light comes on, then slowly turn it down until the light comes off, the amp is adjusted perfectly. The red across the top is the amp’s LED.
