One look at John Wittenzellner's Honda Civic will tell you — here's a man who takes his automobile seriously. The exterior makes a powerful statement — from the exquisite blue paint job to the striking custom wheels. It's no surprise, then, that the Civic's sound system reflects the same attention to detail and performance.

Sony's CDX-6700 CD receiver, with its top-of-the-line tuner, three sets of preamp outputs, CD/MD changer controls, and built-in high- and low-pass crossovers, serves as the heart of John's system. The CDX-727 10-disc CD changer (mounted under the trunk floor in the wheel well) provides instant access to hours of tunes. John installed two Polk Audio EX2550 5-1/4" component systems — one in the front doors and one on the rear deck — for crystal-clear imaging throughout the vehicle (the Polk 2-way crossovers are mounted in the doors and under the rear deck). An Infinity Kappa 54a 4-channel amplifier sends 50 watts RMS to each woofer/tweeter combination. The CDX-6700's high-pass crossover eliminates everything below 120 Hz from the Polk speakers.

Two Q-Logic hatchback boxes sit in the trunk, each housing a 10" Rockford Fosgate HE2 DVC (dual voice coil) subwoofer, handling frequencies from 120 Hz down. The Infinity Beta Digital 100 amplifier sends 200 watts RMS to each of the subs (whose dual voice coils are wired in parallel for 2-ohm impedance). A Lightning Audio 1-farad Strike Cap maintains a smooth flow of power to the Infinity amps. To minimize the possibility of noise problems, John routed Stinger HPM Series 4-gauge power cable down the right side of the car, StreetWires speaker wire on the left side, and Stinger Dream Series patch cables in the center. All power distribution components (distribution blocks, terminals, etc.) are Stinger HPM Platinum.

The Strike capacitor, distribution blocks, and two Infinity amps are mounted on an upholstered board, which is attached to the rear seat back. When the seat drops down, the amps are visible and the subs fire directly into the cab. Cool system, nice ride. Thanks, John, for a look at your sublime Civic!


John Wittenzellner's 1993 Honda Civic.


Sony's CDX-6700 reigns supreme over the Civic's system, with its three sets of preamp outputs, D Bass low frequency enhancement, and built-in high- and low-pass filters.


The Polk EX2550 5-1/4" component system gets plenty of juice in the front doors, courtesy of the Infinity 54a four-channel amp.


John installed Polk's sweet-sounding 3/4" silk/polymer composite tweeters on the Civic's side panel, with the 5-1/4" woofers in the factory openings on the rear deck.


Infinity's Kappa 54a and Beta Digital 100 amplifiers make Martha Stewart proud — excellent color-coordination with the Lightning Audio Strike Cap!


The two Rockford Fosgate HE2 DVC 10" subs soak up some rays with the trunk open. The amp board is visible in the background (back seat is up).
