This month in Street Trucks Magazine, Nathan “Stewart” McGregor’s fully restored, 2007 Chevy SIlverado 1500 was featured on the cover, fully equipped with MB Quart car audio products. This article, written by Mike Alexander, covered this beautiful, custom truck in full detail, showing how Stewart fully transformed this truck. Stewart’s truck was also shown at the SEMA 2015 show in Las Vegas, NV. You can read the full blog on that here.

“Nathan “Stewart” McGregor (aka Peabody) is one of the elite few highly motivated truck enthusiasts, and he’s rediscovered time and time again what it means to tether one’s heart to the industry,” said Alexander.

This truck was completely updated and redone with all new suspension, an Italian Black Mamba leather interior with black suede inserts, and a completely shaved, debadged, smoothed, and bead-rolled body. Stewart also installed all MB Quart car audio in the truck to give it the best sound possible.

He equipped the truck with MB Quart Discus 600.4 amps for the highs and mids, MB Quart Discus 2000.4 amps for the subwoofers, four 12 inch MB Quart MSI-304 subwoofers, and 3 sets of QS216 Speaker Systems 6.5 inch components. Each set is comprised of a pair of 40mm WideSphere™ Teteron silk dome tweeters allowing flawless reproduction of sound and improved durability. The midrange are handled by a Nomex composite cone with a cast aluminum basket all controlled by the Q Control crossovers with attenuation for the tweeter and the midrange.
