Tweak the sound to high-fidelity 
If you're a sound tweaker like me, you'll love JL Audio's TwK 88 System Tuning Processor for all the powerful and detailed adjustments it can apply to your vehicle's sound system. With JL Audio's TwK-TüN app on your laptop or tablet, you'll gain access to real-time tuning that can really dial in your system, including 10-band equalization, variable high- and low-pass filtering, and time delay/alignment on every channel.
It's as easy or complicated as you want
JL Audio has given the TwK 88 three Project Levels of tuning complexity (Basic, Advanced, and Expert) so you'll get fantastic sound no matter how much experience you've had tuning an audio system. The Basic Level guides you through the setups, options, and simple adjustments to achieve great sound in about 10 minutes. The Advanced Level adds extra crossover features, limited-parametric equalization, and delay/time alignment — for a tune-up that takes about 30 to 60 minutes. The Expert Project Level gives you free rein with fully manual adjustments and assignments, fully-parametric EQs, and advanced signal diagnostics, so you can take as much time as you like to play around with the sound.
Versatile connections and controls
Digital inputs and outputs ensure the cleanest, highest-quality signal connections for your TwK 88 processor in a high-definition audio system. You'll use the wired dash-mount remote to control master and subwoofer volume, select user presets, and check on the operational status of the TwK 88 so you'll know what's going on from the driver's seat.
