Custom-Installed Electronic Upgrades

Professional Mobile Service – We come to your home or office

Highest Quality Workmanship Created with Passion

This business is a natural outgrowth of my love of automobiles and electronics. I never feel as if I am actually “working”, so my customers always get the highest quality workmanship.  I treat every car as if it were my own.  I have been doing this since 1982 and I love what I do.  One of my customers says my approach is “persnickety” and “fastidious”.

– David Gold, during a recent interview

K40 & Escort Radar and Laser Warning Systems

Custom-installed, highest technology systems to protect you from radar and laser-based speeding tickets. Damage-free, hidden installations both inside and outside your car!

Rear Seat Entertainment Systems

Imagine total silence from the back seat on long trips! That’s the reality with our custom-installed systems. Leather is a perfect match for grain, color, even stitching color!

Remote Start

Cool down your car in summer! Heat it up in Winter! We are Authorized Dealers for Compustar and iDataLink, the most sophisticated and reliable remote starters made. Ask about Drone Mobile – control your vehicle with unlimited range from a smartphone!

The owner, David Gold, has been an FAA-certificated Airframe & Powerplant Mechanic since 1979. He performs all of the installations, which means you get consistent high-quality results. And he has an old-school customer service policy of treating customers the way you deserve to be treated. He is the only person who will ever touch your cars. Here’s a summary direct from David:


Think SPF: I make your time behind the wheel SAFER, more PRODUCTIVE and more FUN through technology upgrades and training.
I provide custom installation of automotive electronics as a mobile service, performed at the customer’s home or office. I am a K40 Premier Installing Dealer as well as an Escort Authorized Specialist, and can protect your car from radar and laser speeding tickets in all weather conditions, day or night. I cover the entire East coast of the USA from Maine to Florida, and as far West as Texas.

I also love to install Bluetooth telephone systems, GPS navigation, color rearview cameras, blind spot warning, night vision, heated seats, remote start and more. I also have fully-equipped workshops in Charlotte, North Carolina and Greenland, New Hampshire as an alternative to working at your home or office.

What Our Customers Have to Say

“This radio upgrade is awesome. “

This radio upgrade for my daughter’s Subaru is awesome. Since it has much more power, it sounds better and she stays safe with the ability to keep her iPhone out of her hands while driving. She can receive phone calls without touching anything thanks to Auto Answer! If my daughter is safe, I’m happy.

Jim Petrucelli

“Great professional service with attention to detail.”

David was great, he installed a remote starter and it came out awesome. He even picked up the car, did the installation, cleaned it and refueled it before returning it. Great professional service with attention to detail. My mother is now so happy to have a remote starter in her car, it is all she talks about. I will be recommending David to all my friends and family!
