LE Loaded Enclosures: All About That BASS, No Trouble

DD Audio Product Spotlight | WRITTEN BY KEVIN DOYLE | 20 November 2017

The easiest way to instantly improve your vehicle’s sound system is to add sub stage reinforcement. As easy as it may be, there are still a few obstacles people run into when they consider quenching their thirst for better sound through more bass.

Luckily, DD has developed the LE Series of pre-loaded enclosures. The LE Series clears the road to audio bliss for these deprived, yet hesitant individuals.

Obstacle 1: It’s too expensive.

With the LE Series starting at just $199, it leaves room in your budget to get a matching DD Audio amplifier and door speakers. If you want even more savings, present this 10% off coupon to your DD dealer for a discount on qualifying upgrade options.

Obstacle 2: It’s too much hassle to put together a properly designed sub system.

DD has done all the enclosure design and matching work for you. The LE pre-loaded enclosures use the DD Box system which was developed to work specifically with DD subs. Unlike the wimpy economy subs most other companies preload their enclosures with, the DD Audio LE Series is equipped with one of our 500 Series subwoofers. The 500 Series subs have a 1200 Watt burst power rating and feature Dual Voice Coils. This allows the LE enclosures to handle some real power, and they can be wired at 1 or 4 Ohm from maximum flexibility when finding the perfect DD Audio amp.

Obstacle 3: It’ll take up too much precious cargo space to get some actual hard hitting bass.

By using the DD Box system, these enclosures have been intelligently designed to produce big, accurate, bass from a compact space. The smallest footprint in the series is just 5×16 inches (LE-S), which leaves you plenty enough room for groceries, luggage, or whatever else you need to toss in the cargo area (see photos below).

Performance aside, the LE enclosures look awesome! They boast an embroidered DD Audio logo on black carpet and protective bar-grill. If you’re ready to Upgrade Your Sound™, hop into your nearest DD Audio authorized dealer and have a listen. Most people are impressed by the power these babies pack. Find your local DD dealer.

Install Highlight: 2015 Cadillac XTS


Most mobile audio fans at some point wax poetic about what we would do if we had no real restrictions for a build, but the true fact is that most of us have glaring restrictions that keep us from realizing those goals. Luckily for us, there are those daring souls who put it all out there, reach for the stars, and achieve the greatness that motivates us all to do better than we have before. This build is a shining example of what is possible when the right ideas, equipment, and talent all collide in a beautiful symphony of resplendence.

For most folks, just having a 2015 Cadillac XTS is already a victory of sorts. It’s the kind of car that says, “Hey, I’ve made it. I have ARRIVED.” Now, take that same vehicle, drizzle it with a stunner of a two tone Kandy Brandywine paint job, making certain not to leave out the tasteful adornment of the trim as well, set that monster on 26” Forgiato’s (color matched, of course) and you’ve set the bar pretty high for your infotainment upgrades to live up to. This is where the hardworking team at Xtreme Audio and Performance in Ocala, FL, come into play.

They were able to stuff a monster system in this boulevard beast, worthy of the vessel that would contain it. From the custom enclosure to the fabrication of the door panels to the expert upholstery work, the results speak for themselves (look at that headliner!). The talented crew at Xtreme Audio was able to cram in the following DD products to get this bad Caddy rockin’.

3 – Shuriken SK-BT120 battery
1 – LC6i Audio control
1 – DD X1 Signal Processor
2 – DD M2 Amplifier
2 – DD C3d Amplifier
1 – DD C5d Amplifier
4 – DD 3512 Subwoofers
10 – DD VO-B3 Tweeters
10 – DD VO-M8 Drivers

When asked about how he learned of DD as a brand, owner TJ Lafferty recalled having heard the brand mentioned amongst his group of 12v minded brethren and so, he figured he would give them a shot. He has never had to look back and even features DD Audio as his go-to gear at his second location. He went on to say that the combination of quality product and satisfied customers made DD Audio his choice of gear, including in his own personal vehicles.

Remember, if you are like most of us and dream of a system on another level, check out some DD Audio gear at your local dealer, and if you are fortunate enough to live in central Florida, go see the experts at Xtreme Audio and Performance and let your dreams run wild!

Tech Talk: A Beginner’s Guide to Car Audio Competitions

Tech Talk | WRITTEN BY AARON TRIMBLE | 24 October 2017

The 2017 Car Audio Competition Season is drawing to a close. This month USACi, IASCA, dB Drag, MECA, MidwestSPL, and others are all holding their finals. As of writing this article, both USACi’s finals in Wichita Falls, TX and Unified Finals in Louisville, KY have concluded. A few late season finishers like Midwest SPL are hosting their finals this Halloween weekend. However, after attending the first two finals, it can be said with great confidence that attendance is up, and not just at finals either. Attendance even at smaller regional shows is starting to pick up again. There’s a buzz in the air and it’s not just in the Demo Arena!

What does this mean for the “scene” though? It means that there will be a lot of new blood coming into the lanes for 2018. Enthusiasts; license plate rattler’s and traffic light bumper’s from across the country are revitalizing a sport that used to overload exhibition halls and race tracks only a few years ago. It’s an exciting time in car audio competition; new innovations and technological advancements are making it easier for novices to compete. Innovations in tandem with technological advancements like clamped power classes make it much easier for new competitors who don’t have cheater amps or a billion watts of power to be able to compete at a more reasonable level without automatically being thrown into classes way out of their league.

Some of you reading this may be car audio junkies wanting to get into the sport. It can be intimidating to try and slog through which organizations you should compete in, or which class your car fits into. Some of you may be afraid to compete because you don’t think that your two 12’s and your 1000 watt amp will be able to be competitive. These are reasonable concerns to be sure, but if you plan correctly, you can have a blast as a rookie competitor. In this month’s Tech Tip, we’ll help you navigate the competition byways to make sure you have the most fun possible when you compete in the lanes.

Car Audio Competition lanes

Steps for competing in the Lanes

Maybe you’ve never been to a show, or maybe it’s been years since you’ve competed and now you’re coming back to see that the entire landscape of car audio competition has changed. Whatever the reason is, there are few things that you can do to make sure that you get the most from a show.

1. Organizations

The first thing any prospective competitor should be nailing down is what shows are coming up. Determining what is available in your area is a good way of gauging which organization to compete in. This is not to say that you can’t compete in IASCA if 90% of the local shows in an area are USACi. However, if you have an interest in going to championships at the end of the year, you will need to accrue points in order to be invited to the end of the year finals. This is true for every major competition organization, so if you do happen to have a majority of your local shows hosted by a particular group you may want to read up on them to decide if they are a good fit. Each organization has a variety of competition formats, so there’s generally something for everybody.  We’ve included links for a few of the major organizations at the bottom of the article where you can find out about local shows and scope out rules for competition.

2. Formats

Once you’ve determined what’s in your local area it’s time to decide what you want to compete in. Are you interested in chasing numbers with sine-waves in a peak SPL style competition, or is being crowned Demo King in a musical average contest more your speed? Burp and music are the two primary competition formats. Burp cars are built around achieving the absolute peak volume possible from a system within the parameters of the class. You are generally given 30 seconds to play a sine wave of your choice through your car’s system. Whatever the peak value that the microphone picks up is, becomes your score. In musical classes, you’ll be running your system while playing a song (generally of your choice) and the microphone will measure a running average score. Your average score at the end of the run will become your score.

There are also formats that are unique to specific organizations. For example, in dB Drag you can compete in Bass Race which is a competition of skill and familiarity with your system. In Bass Race you choose a class. These classes range from 119.9 to 159.9. The class you choose determines the score you need to shoot for on a musical average. It’s like a “The Price is Right” competition style. You must average as close to your class number as possible without going over and being DQ’d. In USACi, there is a format called port wars. Port wars operates in much the same way that a burp or SPL peak class works, with the exception that the microphone is physically placed in the port. The scores are generally much higher than in normal SPL formats. There are also some torture formats like MidwestSPL’s Kaos. In Kaos, you’ll run your system to the ragged edge for 90 whole seconds to achieve the highest musical average possible. Torture style classes can be very dangerous for equipment, so if you choose to compete in these formats be sure you know your system and how much in can take. Nothing ruins a show like having to rebuild woofers at the end of it.

3. Classes

Now that you know what you’re interested in competing in, it’s time to decide what class you fit in. Showing up to a show on a whim is fine, but if you want to be competitive in your class it pays to know where you fit in. If you’ve got four 15’s in the back of a Tahoe, you should expect many of your fellow competitors to have a lot of power to accompany that. Large cone area classes generally allow for more alternators and batteries and/or more power, whereas smaller cone area classes generally limit the amount of power you’re allowed to use. Lower power classes generally limit the amount of vehicle modifications that you’re allowed to perform. For example, in a Basic class, you’ll likely not be able to remove seats or reinforce panels to increase your score. In Big classes with lots of cone area, you may run into  walled cars where the backs of vehicles are sacrificed to make giant walls of woofers and enclosures that occupy the entire cargo sections of a car. Be sure to read up on the rules for classes in the organization and format you choose to run in.

4. Your First Show

Once you know where and how you’re going to compete it’s time to go to a show. Don’t worry about winning the first time. Go to the show and learn how to compete. Watch other competitors do their runs, and don’t be afraid to ask questions if you don’t understand something. Learn what your competition is and when it’s your turn to compete, see how you stack up against others in your class. Getting an idea of how to run in the lanes, learning how to roll into a burp or knowing when to start a song in a music format can make a huge difference in scores. A car that can beat you by a couple decibels can still be beat if you time your run better than your fellow competitor. Even if you walk away from the event without a trophy, you’ll have a better idea of how to approach the next show.

6. The Next Step

The next step is to get louder and to do that there’s a wide variety of ways to succeed.  The easiest way to get louder is to buy bigger gear. Just make sure that the new batteries, bigger amp, bigger subs, or whatever else you choose to invest in are still compliant with the class you want to compete in.

Now, if you aren’t made of money, there are far more economical ways to improve your scores. You can work on your install. Things to consider are building a new enclosure or modifying your current enclosure or you can also put some sound deadening into your vehicle where panel flex is noticeable to reduce acoustic loses. If you’re looking for something even less expensive or potentially even free, you can search out a TermLab. A TermLab is the piece of measurement equipment that all current competition organizations use to evaluate scores at a show. Often times you can rent time with one at your local Car Audio Shop for a small hourly fee, or if you’re in luck you have a friend or a fellow competitor who’ll let you rent or use theirs.  Either way, having a TermLab available to test and tune your vehicle with can return massive gains in output. Acoustics are fickle. Even minute changes in the vehicle like changing the position of your seat or folding down a sun visor can change a score by a few tenths of a decibel. A tenth of a decibel can mean winning or losing at a show, but it’s too small of an increment in output to be able to physically hear, so having a TermLab available that can detect these small changes is tremendously helpful. You can also try things like moving your enclosure around in the vehicle to see if you can gain output that way.  Often times there is an optimal spot in a vehicle where the enclosure is able to load off panels in the vehicle in such a way that it increases your score. Be creative and have fun finding new ways to get louder, because at the end of the day, it’s all about fun, right?
