JL Audio's VX800/8i 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. JL Audio's VXi Amplifiers do just that.

The VX800/8i 8-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?

great amp

The following review is for VX800/8i, which is a part of the bundle you are viewing.

absolutely the best-sounding amp I've ever had complimented my JL speakers and subs. The best thing about this amp is how small it is.. it takes up LESS space then 2 4 channel amps !!!!! built-in DSP speaks for itself!

Great amp but……

The following review is for VX800/8i, which is a part of the bundle you are viewing.

The only thing keeping this from 5 stars is the cheap plastic connector for the digital input. Mine broke day 1 and now I get intermittent sound. You would think something so critical would be reinforced or build into the housing better especially on a $1,700+ amp. My pac pro even has something more robust and reliable.
