The Owner

Chuck Priebe is a single oilfield dad and Chuck loves car audio.  

The bass bug bit him in high school, back in the 90’s. Since then, he’s had multiple builds, ranging from mild to semi-wild. 

Chuck’s current bass ride is Project Heavy Duty, a 2015 Dodge Ram 2500 Mega Cab with serious bass.

The Story

Chuck was drawn to car audio in high school. His peers heavy bass systems inspired him to build his own. 

He wanted to be the loudest in Elk City, his small town of 3000 people in Oklahoma.

After his friends opened Advantage Audio, he had them build several vehicles, which he took to car shows. 

Then Chuck got married, had kids, and took a 17 year break from car audio. 

When he showed his son some old vehicles and competition stats, the bass bug bit a second generation of Priebes. 

The kids are driving now and both of them have audio systems in their vehicles, which they built together.

Car audio is turning into a family affair, which is exactly what he hoped for!

Chuck’s daughter is competing in her first SPL competition this weekend. Wish her luck, high Db’s, and low bass.

After seeing the potential in his dad’s truck, Chuck’s son asked if they could complete together, the ultimate father-son activity! 

His son wanted to know how much they could get away with in his dad’s Ram, which sparked a fire in Chuck. 

The Builder

Chuck reached out to long time friend and builders, Lance Pitzer and Chris Gerhold of Advantage Audio in Elk City, Oklahoma.

Lance and Chris put over 400 hours into Project Heavy Duyty. 

The most challenging part for Chuck was deciding which subwoofers to use and how much space to give up in his vehicle. 

After careful consideration and deliberation, Chuck chose a blow-through enclosure, as it made room for a large subwoofer box without sacrificing cabin space.

The Gear

Chuck settled on two DD Audio ESP D-4 9518’s in a 36 cubic foot, 6th order blow through enclosure. His back ports are tuned to 26-28 Hz and his front port is tuned to 60Hz. 

There are two S1-2250.1 Monoblock Amplifiers powering his windy build. 

For the door speakers, Chuck chose Focal Audio, which were installed in the factory door panels. He is using a Mosconi one 130.4 multiple channel amplifier.

The total cost for Project Heavy Duty was $11,000.

To support the current needs of his truck, Chuck has two Odessy Extreme Batteries and a Mechman 370 Amp Alternator. 

Project Heavy Duty has the Big Three on both batteries, with two runs of 1/0 AWG from the batteries to the amplifiers, as well as two runs of 1/0 AWG Ground Wiring.
