Hey Guys. It's been a while since I've posted anything, or even been on the forum. I'm going to try to post up some builds on a bit more regular basis.

Here's the first one:

In August 2015, we were contacted by Focal America to see if we were available to build a car for them. It's always a good feeling when a manufacturer recognizes the quality of your work and wants you to build their next demo vehicle. Later, we found out that we would be building the first car in the world to have the NEW Focal K2 Power speakers and NEW prototype Focal FPD Amplifiers. We were honored and excited! We have been unable to share details of the build publicly until after the NEW speakers were unveiled to the rest of the world at the Consumer Electronics Show in January.

Here's the car.


When any build like this comes in, the first thing we do is take a look at the factory audio signal and determine the best approach to integrate the new equipment. Fortunately, like many Nissan and Infiniti vehicles equipped with the factory BOSE audio system, the signal between the headunit is balanced, low voltage, volume variable and pretty flat.

Rear Signal


Front Outputs with 1k Sine Wave. Over 3v unclipped, not bad.


Here is the unboxing of the prototype Focals. As you can see, these were not in retail packaging.












On to the Build Pictures.

We'll start in the front and move back. We modified the factory ash tray to mount the Mosconi RC-Mini Controller. We also remote mounted the LED clipping indicator from the amplifier remote sub level knob next to the cigarette lighter socket. We used Molex Mini Fit connectors to maintain remove-ability and serviceability of the panel.







On to the doors. We did a lot of acoustic treatment. The Speaker Mounting Plate adapters are made from Sintra (expanded PVC sheet)

Since we were significantly increasing the amount of power for the midbass in the doors, we wanted to upgrade the speaker wire. Rather than drill holes in the factory Molex plug going to the doors and eliminate the serviceability of the vehicle doors being easily removed. We source the correct molex plug pins to add our new speaker wire through the plug, and maintain the original vehicle functionality.


































We also slightly modified and opened up the factory grill and gave the door panels a complete acoustic treatment.

Here is the wiring throughout the vehicle.



















The A-Pillars presented a challenge because they have defrost vents and the ducting to supply it. We slightly modified and resealed the duct, but kept everything 100% functional. We also did the tweeter on a slightly different angle than the mid to try and get them a bit more on axis.














The A-Pillars were wrapped in suede along with the headliner.

In addition to using prototype speakers for this build, Focal also provided 3 new prototype amplifiers for this build. The new FPD Series amps look similar to the previous generation FDP amps on the outside, but they have made several improvements on the inside. We prefer to use metal to mount and secure equipment, and utilize factory mounting points whenever possible. The forward mounts for the amp rack are factory and we added two 8mm rivnuts for the rear mounts. Servicing the amps was also very important. The the top amplifier is easily removable to allow access to remove the bottom amplifiers.
