JL Audio VX400/4i 4-Channel Amplifier with Built In Digital Signal Processor (DSP)

JL Audio's VX400/4i Amplifier

Sometimes, beauty's only skin deep and other times, it's what's on the inside that counts. But when you find something gorgeous inside and out, you never pass it up. JL Audio's brand new VXi amplifiers are designed not with a balance of beauty and function, but an abundance of both. You get amazing sound and looks.

JL Audio's VX400/4i 4-Channel Amplifier mixes beauty and function

The VX400/4i 4-channel amplifier has a built in Digital Signal Processor (DSP). Instead of concealing the controls behind a metal plate, all the tuning is right at your fingertips. Just connect with the free TüN app.

Once your installation is finished, you can tune from anywhere, and you can change your settings without getting out the tool kit. Adjust the parametric EQs on each channel, the gain and more through a phone, tablet or computer.

But who says looks don't matter? JL Audio placed all the connections on the VXi amps on one side, cleaning up every installation. The chassis hides all the mounting hardware. The logo badge rotates in 90-degree increments, depending on how you need to mount it, and you can change the LED backlight color to match your system. What are you waiting for? Get your VX400/4i now and hit Add to Cart!

JL Audio VX400/4i 4-Channel Amplifier has all the connections on one side.
