I bought my 2014 Hyundai Veloster Turbo used and prior to my ownership it actually was in the care of a Hyundai executive for a year and by the time it got to me, I felt like I got quite a good deal as it was certified pre-owned (meaning it kept its 10 year/100,000 mile powertrain warranty) and because it came with lots of attractive features at a low price. My Turbo came with the uplevel 400-watt Dimension audio system and it was a perfectly serviceable unit with great sound quality if it did seem to lack a little bit in the power department. I like my music loud. Wait, what did you say?
So when JL Audio offered to turn my car into a project vehicle I said sure, why not? Actually, I never believed that they would send me just three days later so many boxes of their equipment that my UPS man intentionally stacked the boxes in front of my door so I wouldn’t be able to get out unless I brought them all inside.
Of course I did that and immediately I headed off to my nearest authorized JL Audio retailer and installation center Viejo Auto Stereo in Mission Viejo where the staff was the picture of helpfulness, full of good advice and always willing to answer my questions. And they did an amazing installation job, somehow they managed to hide everything that would be a dead giveaway to thieves that the car had an expensive audio system inside.
Here is a list of some of the major components that went into our system which continues to provide some of the crispest, clear and potently powerful audio that we have ever experienced even in insanely expensive luxury cars with impressive brand name up-level audio. JL Audio just shows you don’t need to spend a fortune to drive around in a true automotive audiophile’s environment.
C5 Speakers: These JL stalwarts have a level of smoothness and transparency usually reserved for high-end silk dome tweeters combined with class leading woofer performance which combines to create a refined yet dynamically capable audio system.

SB-HY-VELOSTR/10TW3 (Custom sized to fit “Stealthbox)
Hyundai’s funky Veloster defies categorization and offers a great combination of style, practicality and clever packaging. The custom designed JL Audio stealthbox features a potent 10-inch subwoofer housed in a compact, sealed, fiberglass enclosure that fits neatly into the passenger side rear corner of the trunk. The form-fitting design conserves your valuable hatch space while still permitting full access to the spare tire. A clean-looking steel mesh grille protects your investment from loose cargo.
What Comes with the built to fit your car “Stealthbox?;Contains one 10TW3-D4 subwoofer in a sealed enclosure. 400 watts of power and wired for 2 ohm mono, it installs in passenger side of the rear cargo area meaning pretty much no cargo carrying ability at all was lost with the installation of this JL Audio system. And considering how many boxes it came in, that is astonishing.
Connecting to OEM Head Units
As automakers continue to leave behind standard audio head units in favor of integrated touch screen design with all manner of complex connectivity, JL Audio decided there was a need for a high quality integration solution. Their goal was to deliver their usual world-class audio without interfering with the original functionality of the in dash audio/infotainment control unit. It is called the “Clean Sweep.”
CleanSweep OEM Audio Interface with Automatic Digital EQ, 4 channel Inputs + L-R Aux Inputs / 4 channel Outputs to give you aftermarket premium sound while retaining all of the features and functionality of your normal head unit.
Unlike primitive line-output converters that only reduce the level of factory audio signals (which many competitors still use), the CleanSweep® CL441DSP employs a powerful DSP (Digital Signal Processor) to automatically analyze the frequency response of a full-range factory audio signal and then applies 30 bands of powerful equalization to each channel. This counteracts any factory equalization and provides a clean, flat signal so your aftermarket amplifiers and speaker systems sound their best. This means you can use your factory volume control(s) or the included Master Volume control when listening to the factory source unit as well as any other controls on your dash.
The CL441DSP also provides a stereo line-level Auxiliary Input so that you can easily add an additional source to your audio system and with the addition of a CL-SES Source Expander Switch you can add up to three source units. The CL441DSP employs Automatic Signal Sensing to provide remote turn-on and turn-off functionality for your JL amplifiers as well.
This is the codename for the JL Audio Monoblock Class A/B Subwoofer Amplifier which is both a rugged and reliable Class A/B using a robust MOSFET power supply design that delivers rock-solid bass performance without breaking your budget.
This amp is targeted specifically at subwoofer applications, the JX250/1 includes a low-pass filter with continuously variable cutoff frequency selection from 50-200 Hz. It also features a variable bass boost at 45 Hz. with up to 12 dB of boost and an optional remote boost control. Dedicated hi-level inputs are included, in addition to conventional low-level RCA inputs, this all makes it easy to integrate JL Audio’s amazingly high quality products with a variety of OEM and aftermarket head units.
