Fine-Tune Your Vehicle's Audio to Perfection!

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.

Three Project Levels for Every Sound Enthusiast, from Novice to Maestro!

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.

 

 

Elevate Your Audio Experience with JL Audio's TwK 88 and High-Definition Digital Connectivity!

Digital inputs and outputs ensure the cleanest, highest-quality signal connections for your TwK 88 processor in a high-definition audio system.

  • Good if it works. Had it professionally installed a one night the temperature dropped and battery was low. Apparently these have a known issue that if battery goes low, processor wont hold programming. Only had it for few months, and drove the car a few times. I wanted a refund for item, but apparently its only a factory warranty. Waste of money. Had to have professionally uninstalled and replaced with another brand from another company. Wasnt going to drive the car around for weeks waiting for repaired junk. Who wants something that doesnt work that good. I was a repeat customer, and not pleased with decision,
