C5 owners have incorporated various upgrades to their cars
interiors. C5 interior mods typically revolve around the many add on
products that are available from the big catalogue companies. The Holy
Grail of C5 interior mods is the installation of a C6 style DVD
navigation system. The reason that an in dash DVD/GPS system was not
offered in C5’s is that the technology was not incorporated into a
Corvette until 2005 under C6 option U3U.
In 2006 Dennis Dummer founder of Double D
Mods in Kieler Wi. decided that he wanted
an in dash navigation system for his 1999 Corvette. He did some
research and found there was nothing available for a C5 that would
allow for the installation of a 1.5 din head unit with built in NAV. A
din is an International ISO standard which defines a standard size for
car audio head units. The standard was originally established by the
German standards body Deutsches Institut Normung, and is commonly
referred to as the "DIN car radio size". Audio head units generally
come in either single DIN (180 x 50 mm panel) or double DIN (180 x 100
mm panel) size. The US standard for a DIN radio is generally considered
to be approximately 2" x 7" and the Double DIN sized radio is a 4" x
Dennis found out that some people had
already done this mod and decided
to give it a try. He purchased a C5 dash bezel off EBAY and transformed
the stock C5 1.5 din radio bezel into a double din radio bezel.
His next step was to head over to a friend
that was an experienced
audiophile. Greg Temple, who was the audio guru helped him install a
Kenwood head unit and managed to replace the entire system. Through
trial and error Dennis learned the ins and outs of Corvette double din
Another good friend, Nouman Saleem, asked
Dennis to make a custom radio
bezel for him but with some different changes. After working on this
project word slowly started to spread on Dennis’s new product. In 2008
Dennis decided to go into business. This was the start of Double D
Over the next two years Dennis fabricated
specialized Corvette dash
bezels on a part time basis in his basement/shop. He made the decision
to leave his full time sales position with a Food Services company and
take the chance on doing this as a full time career.
Dennis found a 3000 sq ft shop facility a
couple miles from home that
was perfect for what we wanted to do. He signed the lease and the rest
is history. Double D Mods has been steadily growing. New items are
constantly being tested and added for sale on his companies’ website.
Double D became a fully Authorized audio dealer for multiple companies
that offer a complete out of the box, install ready package.
The company also offers items such as
wheels, apparel and radar
detectors. Double D is also a well known distributor as a Corvette
source for OBX headers. They are always looking to add more performance
oriented items to their product line and pass the savings to their
Double D Project Car
Dennis was always a big fan
sixties Mopars having owned a
few of them over the years. Dennis wanted something more current so he
decided on a C5 Corvette. He searched for a couple months and finally
decided on a low mileage 1999 Coupe. The C5 had no modifications and
only 23k miles on the odo. After a short time Dennis was bitten by the
mod bug and the fun began.
An extensive list of upgrades to the C5
include upgrading the cars
running shoes with a set of 19 inch Boze Forged Tach Wheels wrapped in
Hankook Ventus rubber. Stopping power is provided by a set of drilled and
slotted brake rotors
by Roylaty Performance. The calipers were also powder coated in red to
match the exterior.
Exterior body modifications include an RK
Sport Ram Air hood that was
custom painted by Lens Paint n Place in Kieler Wi. This is the hood
design that wowed the crowds at the 2008 SEMA show in Vegas.
The hood lines give the C5 a very slick retro look
A radical set of GT Factory Vertical Doors really sets this C5 apart
from the crowd.
The front facia air intakes were fitted with a set of very cool
looking black powder coated screens from Racemesh.
All C5 owners know that the car is prone
to bottom scraping while
entering or exiting a driveway. In an attempt to alleviate this
embarrassing situation a set of Fat Daddy frame savers were installed
on the car.
The engine bay was given some bling with
stainless items from American
Key City Kustoms in Hazel Green Wi
airbrushed the hood liner in classic flames.
Performance upgrades include a set of OBX
long tube headers and BB
catback bullet exhaust system. The LS1 breaths little easier
compliments of an SLP Blackwing cold air intake system. The engine also
gained some extra horses with a revised ECU tune from East Coast
The Holy Grail
Installing a C6 type DVD/NAV unit in a C5 is a major improvement to the
fifth generations interior. The C5 interior is already
one of the best Corvette interiors ever offered by GM. The DVD unit
enhances and updates the C5 overall image.
DD Mods offers a modified and very cool
Hydrocarbon carbon fiber C5 bezel.
The unit is finished in a half leather wrap by Carskinz, Elemental
Designs. Custom AV units feature a JL Audio e 6450 amp, Infinity 6012si
rear speakers, and are powered by a Pioneer X920BT Double Din NAV DVD
The finished product will make you the envy of every non DVD
equipped C5 owner. Many C6 owners will admit that the C5
more styling appeal than the latest rendition of the Corvette. The
addition of a slick carbon fiber console and dash really drives this
C5 like most project cars is a work in
modifications will include turbo or super charged forced
and a LG Coil over suspension. Planned interior mods include
leather seats. The exterior will be upgraded with a Tiger
Dennis asked us to include thanks to all
the people that made his dream
possible. The biggest thanks goes to his step son Dallas for helping in
the fabrication and order fulfillment of these custom parts. Dennis
will be loosing him to the US Navy this year.
