Install Highlight: 1994 Fiat Panda

DD AUDIO INSTALL HIGHLIGHT | WRITTEN BY LEWIS JACKSON | 10 JANUARY 2018

As many of our loyal fanbase knows, DD Audio has long since been a staple in competition here in the states. That is where we made our name, and still hold our own despite the onslaught of potential competition. Just as that bass bug spread domestically the rest of the world has felt it too, just ask our man, Luuk Tissingh, from Car Audio Shop Mag ‘t wat Harder in the Netherlands!

In his shop, which opened in 2012, he and a customer embarked on a project with their 1994 Fiat Panda, aiming to build a demo monster to show what they could do with our products. To say they hit the mark would be an understatement! By the time they finished it, they had a music machine capable of doing a whopping 159dB all day with the door open, giving anyone within earshot a heavy dose of VO goodness.

Those lucky enough to have experienced this animal in person were blown away, not only by the volume and pressure it is able to generate, but the quality of the sound as well. It’s easy to see why with an equipment list like this:

It is only fitting, since Luuk first became familiar with our product in the dB Drag lanes back in 2005, that this little gem is slated for a rebuild to compete in EMMA competition this season. We look forward to seeing what kind of DD gear you stuff in it this time, and best of luck in your classes! Thanks again to the great folks at Car Audio Shop Mag ‘t wat Harder for sharing this with us, and keep up the great work!

Dealer of the Month: Green Toad Audio of Conway, Arkansas

Shop Name: Green Toad Audio
Shop Location: Conway, AR
Owner’s Name: Jeremy Smith

DD: How long have you been in business?:
Jeremy: One year.

DD: How did you get started in car audio?
Jeremy: The staff has always been audiophiles, so car audio was a natural addition to our full service automotive repair shop. My service advisor grew up in LA where his dad was a master audio installer, so he was instrumental in setting up our shop.

DD: What made you decide to do car audio for a living?
Jeremy: Our shop Green Toad Tire & Auto has built a name for drivability diagnostics and a commitment to honesty, integrity and perfection. In our city, there was a virtual hole in the car audio market for someone to become a premiere audio retailer/installer. Couple the two together and car audio just made sense.

DD: Does your shop specialize in anything specific?
Jeremy: We are known for high quality installs and only using top of the line equipment.

DD: How long have you been a DD Audio dealer?
Jeremy: Four months.

DD: Where did you first hear about DD Audio, and why did you decide to become a DD Audio Dealer?
Jeremy: When we ultimately made the decision to add car audio to our services, we wanted to sell and install the best. With that decision, becoming the DD Audio retailer was an easy one because DD Audio is synonymous with being the best in performance for competition and daily driving. Being the audiophiles that we are, we have all heard DD Audio at sound competitions, so our love for their sound began years ago.

Cheers to a New Year – A Message from the CEO

Another year in the books and thanks to our customers continued support DD Audio had a great year and we’re excitedly looking forward to 2018.

As consumers, we’re quickly immersing ourselves into an order via keyboard/keypad era, but DD Audio is confident the world of brick and mortar based custom car audio shops will continue surviving due to the fact the more complicated a major purchase is, the more expert guidance is needed. This expertise comes into play when deciding what will best meet a customer’s needs, helping if something goes wrong or when a customer just wishes to change something more to their liking. This expertise and personal attention is what will continue to bring people into shops to explore their options and then build their dream systems.

We enjoy being in the people business and working with passionate car audio fanatics everyday, that’s what being in the specialist market means for all of us. We’ve worked hard on building a staff and culture to not only listen to what customers need, but to work together on the products that put smiles on peoples faces. This is the bottom line, and what gives us an advantage over personless product acquisitions.

To help with those smiles, our audio elves have been hard at work gearing up for the year to come. They’ve been checking their lists and measuring twice and what they’ve come up with is gonna be nice. We have more power coming your way along with new woofer looks and models. It’s going to be a good year for drivers and riders.

Thanks for letting us be apart of your systems’, having a little extra fun on your way somewhere makes the world a better place.

Happy New Year!

Tech Talk – Check Your Space Before You Buy Your Bass

Tech Talk | WRITTEN BY AARON TRIMBLE | December 2017

Sure, that pair of 18’s will totally fit in your Honda Del Sol! Of course you can fit a 9512 under the seat in your Ford Ranger! Don’t worry, we’ll cut the box for your 15 in half to fit it in the trunk of your new Camaro! Yeah, some of these examples might be a bit hyperbolic, but the DD Audio Tech Support team does get some doozies. Today we’re going to look at what you can do to fit the biggest woofers in your car without sacrificing performance by forcing a woofer to go in an enclosure that’s just too small.

We’re going to assume that you want to maximize the performance of the space you have in your vehicle. After all, if you’re just looking for a little bass in your Tahoe, a pair of 8’s is still going to fit without having to sweat the numbers. With the handy dandy DD Box Size Graph we can determine what will fit.

We’ve gone through and outlined three DD employee vehicles with unique challenges to show what will fit in a car. For the sake of simplicity, these builds will assume that the car will remain stock and nothing in the vehicle will be removed.

2015 Subaru Impreza Sport Wagon

2105 Subaru Impreza Cargo Area

This guy is a basshead, he’s totally cool with giving up his whole cargo area to feed the beast, as long as it fits under the cargo cover. Now, there’s two ways to look at this vehicle. From wheel well to wheel well the trunk width is 42”, but you can only maintain that width for 14” of depth because the rear of the trunk tapers down to 36.5” at the hatch opening. If we only build the enclosure to be 36.5” wide we can increase the depth of the enclosure to 22” in depth. For either approach, we can build the enclosure as high as the cargo cover which is 15.5”. We’re going to construct this enclosure out of ¾” MDF, so we’re going to subtract our material thickness from all sides to get a realistic gross volume to work with.

Option 1:
External Dimensions – 42.0” x 14.0” x 15.5”
Internal Dimensions – 40.5” x 12.5” x 14.0” = 7087.5 cubic inches or 4.10 cubic feet

Option 2:
External Dimensions – 36.5” x 22.0” x 15.5”
Internal Dimensions – 35.0” x 20.5” x 14.0” = 10045.0 cubic inches of 5.81 cubic feet

Option 2 in this case allows us more airspace and is a dimension that allows the enclosure to be slid into the cargo area without having to fold down the seat and wrestle with it like Option 1 would. The other main difference with Option 2 is that we will be forced to fire the woofers up and the port up or to the side, vs being able to run everything firing back like we would be able to with option one due to the proximity of the enclosure to the rear hatch. So, 5.81 cubic feet is our gross airspace, from this we’ll need to subtract bracing, woofer/s, and port displacement. Those of us who’ve been on the DD Support pages will remember our easy displacement values, if not, you can read all about them on the DD Box Design Page. Those values are .82 and .77, the values are not absolutes when dealing with strange dimension enclosures, large bracing or excessively low tuning, but they’ll get us in the ballpark. So, if we multiply our 5.81 cubic feet by .77, we get an estimated 4.47 cubic feet. Now that we have loosely estimated our net volume we can use the Box Size Graph to figure out what woofers to put in our Subaru.

4.47 cubic feet is good for:
4 x 8” Subs
3 x 10” Subs
2 x 12” Subs
1 x 15” Subs

Selecting subs is as much preference as it can be performance. Yes, three 10” woofers is the most cone area, but if you don’t want to spend the money on three woofers and instead want to buy a single higher powered 15”, that’s a great option too. The problem arises when you look at your boot and say, “I want two 15”s in there!” Let’s look at another vehicle.

2017 Mazda CX-8

2017 Mazda CX-8 Cargo Area

The CX-8 is a 7 seat, third row SUV. With the third row up, there’s less than 10” in depth. However, the owner of the Mazda says they want to really get some wind moving back there. So, we’re going to do our measurements with the third row seat down, which extends the depth to up to 36” deep! In this example we will again be using ¾” MDF for construction, and just like the Subaru, this car has a couple different ways we can approach the space. The space between the wheel wells is 40” and the opening at the hatch of the vehicle is 42”, so we’ll work with a fixed 40” width. The height and depth are our variables here. If we want to go for the full depth of the boot, we can make the enclosure 36” deep and 13” high before its corners will begin to hit the hatch when it’s closed. Alternatively we can decrease the depth to 32” and increase the height to the top of the second row seat (16 inches) which also allows us to fire the port back without and port loading issues.

Option 1:
External Dimensions – 40.0” x 36.0” x 13.0”
Internal Dimensions – 38.5” x 34.5” x 11.5” = 15274.9 cubic inches or 8.84 cubic feet

Option 2:
External Dimensions – 40.0” x 32.0” x 16.0”
Internal Dimension – 38.5” x 30.5” x 14.5” = 17026.6 cubic inches or 9.85 cubic feet

Option 2 is going to be the best option for us here since it’s larger and still allows us to fire woofer(s) up and the port back in a classic SUV style enclosure. Using our .77 to give an estimated space occupation for woofer(s) and port, 9.85 cubic feet gross will become 7.58 cubic feet net.

7.58 cubic feet is good for:
6 x 10”
4 x 12”
2 x 15”
1 x 18”

With this much space there’s a lot of different combinations of woofers that can be made. For example, DD 12’s work well in enclosures from 1.75 to 2.75 cubic foot enclosures depending on model and applied power. So, in 7.5 cubic feet, depending on performance goals you could do three or four 12” subs. If the debate was between three or four 12” subs, there may be some mitigating factors to consider. If you’re going to be using an M3c (3800 watts at 1 ohm), you could best capitalize on this power with four 2500 series 12’s (3200 watts RMS) or three 3500 series 12’s (3600 watts RMS). The 2500’s will save you $100 or so and have more cone area, but the 3500’s have larger coils and can come with ESP upgrades, so it’s a matter of weighing what is important to you. Let’s examine one last vehicle.

2007 Honda Civic

2007 Honda Civic Cargo Area

The Civic is a little more challenging. The owner is fine with taking up a fair amount of the space in the trunk, but would like to retain some space for groceries. So, in this vehicle after a little discussion we’ve determined that the enclosure needs to leave at least 12” of space towards the bumper. This means that there is a maximum of 16” of depth in this install. The wheel wells are 40” but the trunk tapers at the rear to 32” to pass through to the cabin when the rear seat is folded down. If the enclosure is 32” wide it can fit inside the taper and take advantage of the full 16” depth, it will however be limited to 14” in height. If the enclosure is 40” wide, it will lose 3” of depth, but gain 2” in height. This enclosure has a lot more variables.

Option 1:
External Dimensions – 32.0” x 16.0” x 14.0”
Internal Dimensions – 30.5” x 14.5” x 12.5” = 5528.1 cubic inches or 3.2 cubic feet

Option 2:
External Dimensions – 40.0” x 13.0” x 16.0”
Internal Dimensions – 38.5” x 11.5” x 14.5” = 6419.9 cubic inches or 3.72 cubic feet

In this application, because of the depth limitation, there isn’t a significant difference in overall volume. When we look at estimated net volumes we’re comparing 2.46 and 2.86 cubic feet respectively, which is about a 14% difference in size. 14% in this case isn’t going to allow us to do a 15” woofer in either option, nor is it going to allow us to go from using two 10” subs to three or anything like that. Because the volume differences do not provide any significant improvements in cone area potential or in listenable performance we can opt for the more convenient enclosure; both to construct and for the owner to use and move around. In this case we’ll use Option 1 because it will be both a more efficient use of wood and it will easily slide into and out of the trunk without unnecessary maneuvers like having to slide it in sideways then right it once it’s in the trunk.

2.46 cubic feet is good for:
3 x 8”
2 x 10”
1 x 12”

The Civic is a prime example of a vehicle where someone might get over zealous. Yes, there is more room available in the trunk and if owner of the vehicle wasn’t concerned about being able to still use some of their trunk, we’d have had almost 5.85 cubic feet of estimated net volume. At that point you could squeeze in an 18”. However, an 18” would only be able to fit on the top of the enclosure which would be about an 1.5” from the top without accommodating for a double baffle that a woofer of that stature would necessitate. It becomes impractical. Knowing what will fit in a vehicle, and what should fit in a vehicle can mean the difference between boinky, hollow bass and something that can play deep and sound full like it should. So remember, check your space before you buy your bass.
