Jonathan Kim turned to his brother Chris, an experienced installer, to tackle the job of outfitting his 2000 Silverado. They began by choosing Sony's CDX-M670 head unit as the center of the system. This versatile Mobile ES receiver features 5.5-volt front, rear, and subwoofer preamp outputs, subwoofer level control, a built-in 7-band equalizer, and a very cool-looking Active Black Panel detachable face. To fuel those long drive music marathons, the two brothers installed the Sony CDX-715 10-disc changer in the center console between the two front seats.

Chris dropped the 6-1/2" quartz-injected poly woofers (from the Infinity Kappa 60.2cs component system) into the factory door openings, building custom mounts for the 1" ceramic-composite dome tweeters. A pair of Infinity Kappa 462.3cfp plate speakers replaced the factory 4"x6"s in the rear doors. Dynamat Xtreme was used to eliminate potential resonance in the front and rear doors.

The Kenwood Excelon KAC-X501F amplifier (75 watts RMS x 4) powers the Infinity speakers in the front and rear doors. The adjustable high-pass crossover (set at 120 Hz) filters out unwanted low frequencies and keeps the sound from the Kappas crisp and clean at high levels. The Kenwood Excelon KAC-X401M mono subwoofer amp sends a roaring 600 watts x 1 (at 2 ohms) to two Audiobahn AW100S 10" subwoofers for some massive bass (from 80 Hz down).

Q-Logic's QL-C1GTXAMP custom amp rack and two QL-C1GTX110 custom-fit enclosures hide the mono amplifier and the two Audiobahn subs under the rear seat without losing any passenger space. The 4-channel amp was installed on the floorboard immediately behind the front-passenger seat and a carpeted custom enclosure was built to hide and protect the amplifier. The crossovers from the Infinity separates were installed under the front passenger seat.

Stinger power and ground leads, battery and ring terminals, battery covers, and distribution blocks are used for all power connections, while the audio signal travels through Rockford Fosgate interconnects. Chris ran 0-gauge power cable from the battery all the way to the distribution block on the Silverado's rear wall, with 4-gauge leads to each Kenwood amp. A Precision Power 1-farad Capacitor keeps the KAC-X401M sub amp fully fueled with extra voltage.

The truck has competed successfully in USAC Sound Quality (SQ) competitions. Chris (with Jon's help) did all the work on this totally professional installation, and some upgrades to the system are already in the works. We haven't been filled in on the details, but we hear the back seat's getting a little worried. Jon and Chris, thanks for letting us check out your sweet-looking Silverado!

The Active Black Panel face on the CDX-M670 CD receiver flips out to reveal the CD slot and silver control panel. When the face is up, all receiver functions are controlled by the remote.


The center console flips up to reveal the Sony CDX-715 10-disc CD changer. Its Custom File feature lets you title up to 110 discs.


Chris Kim installed the Infinity Kappa 4"x6" plate speaker in the rear door. The Dynamat Xtreme reinforces the door metal, improving speaker accuracy and eliminating rattles.


With the rear seat removed in this under-construction photo, you can see both Kenwood amps and a custom-fit Q-Logic enclosure housing an Audiobahn sub.


The finished product — the rear seat flips up to reveal both Q-Logic sub boxes, Q-Logic amp rack, and the Kenwood amps. With 600 watts pushing the two Audiobahn 10" subs, it's gotta be tough on hitchhikers!
