Are you looking for a full-range car amplifier that is compact and can pack a lot of punch? The JL Audio 400/4 is maybe what you are looking for. This 4-channel car amplifier can easily be installed anywhere inside your vehicle as it does not need much space to power up your vehicle's audio system.
The JL Audio 400/4 also comes with a 3-way protection circuitry that protects your amplifier from thermal, overload, and short circuit problems. With JL Audio's NexD Switching Technology, the amplifier can deliver superior power output with reduced distortion. It also has Differential-Balanced Inputs, eliminating noise from your connections and setup.
Thanks to its Class-D amplifier, the JL Audio 400/4 can handle a power output of 75 Watts RMS at 4 ohms and 100 Watts RMS at 2 ohms per channel. It has a signal-to-noise ratio rate of 108 dB and a frequency response of 12 Hz to 22 kHz, which really allows the amplifier to go loud with minimal distortion while still being able to deliver an extensive full-range frequency performance.
Although the JL Audio 400/4 is a four-channel amplifier, you can set it in a two-channel mode, allowing you to power up a pair of subwoofers while delivering 200 Watts of continuous power output. Lastly, it has variable high and low-pass filters to filter out unwanted frequencies, resulting in a more defined audio quality while protecting your speakers from blowing off.

Perfect for my 6.5 front and 6x9 rear speakers. Does the job well. Actually, it gives more than what I expected. For its price? It’s worth it. You can never go wrong with JL Audio.
Can’t complain. Very affordable amp, compact and gives clean power. JL Audio has yet to disappoint me.

Best 4 channel amp
JL AUDIO amplifiers are totally the best! I always a great experience with their amps so I did not let go of the chance to get a new one at a very low price. With its ability to deliver 100 watts per speaker, it really does not break a sweat pushing my system to high volume levels.
Powerful multi-amp from JL Audio! Its capacity to deliver 100 watts RMS per channel is really more than enough to make my audio system sing and shout! You can also try out different settings with this amp but I don’t understand anything of this yet.
Running my front and rear speakers on the amp. So much power for the size. A true class D amplifier! Sound quality is top notch, and its the cleanest thing I’ve heard in a long long time. Controls like the filters also makes the sound much more better.
Hands down one of the best 4 channel amp in the market today. Crisp and clear sound, and its powerful enough to run my front and rear speakers smoothly. Totally impressed with what this amp can deliver
