Photo 2/17 | Sound Logic Polk Audio System Door Panel Removal | The process began at Audio Innovations, in Glendora, California, with removing the truck's door panels, which are held in place by three 10mm bolts: two beneath the armrest and one in front of the handle. The door lock tabs were also popped out using a small flathead screwdriver, then the panels were set aside.
Photo 3/17 | Sound Logic Polk Audio System Original Speaker | Here's what the original paper door speakers looked like—pretty pitiful. The tan plastic bracket could now be unbolted and the speaker wires snipped, freeing the speaker from the door.
Photo 4/17 | Sound Logic Polk Audio System Removing Stock Speaker Cones | In order to fit the new Polk Audio speakers to the Silverado's doors, we needed to reuse the tan plastic portion of the stock speakers, so the stock speaker cones had to go. The cones were simply peeled back by hand and thrown away.
Photo 5/17 | Sound Logic Polk Audio System Cut Bracket | To make room for the deeper Polk Audio speaker magnets, the center portion of each bracket was cut out using an air saw. Then, the raised outer rims were sanded smooth with a rotary sander.
Photo 6/17 | Sound Logic Polk Audio System New And Old Speaker Comparison | With the brackets modified, the new speakers were screwed securely in place using a power drill. Here's how the new component speaker looks compared to the old Chevy coaxial.
Photo 7/17 | Sound Logic Polk Audio System Stripping Speaker Wires | Since we're not pushing crazy amounts of power through our system, we opted to reuse the truck's original speaker wires. The ends were stripped, and spade connectors crimped on before hooking up the new speakers.
Photo 8/17 | Sound Logic Polk Audio System Bolting In New Speaker | With the new door speakers connected, the brackets were simply bolted back down. The StP sound deadening from LMC Truck we applied before upgrading to the LMC Truck carpet should help focus the sound inward, as well as road noise and vibration.
Photo 9/17 | Sound Logic Polk Audio System Unbolting Old Rear Speaker | Moving on to the rear speakers, the plastic panels behind the doors were removed, as were the upper seatbelt mounts. Then, the speakers themselves were unbolted, disconnected, and thrown away.
Photo 10/17 | Sound Logic Polk Audio System Connecting New Speaker | The new Polk DXi460p speakers were connected to the original wiring with spade connectors, then screwed in place of the old factory speakers.
Photo 11/17 | Sound Logic Polk Audio System Power Wires | Before installing the amp, power wire was run from the fuse box to the rear of the cab, as well as RCA cables to convey audio from the head unit to the amp's inputs.
Photo 12/17 | Sound Logic Polk Audio System Installing Amp | Fortunately for us, the seats were already out of the truck from the carpet upgrade, so we had easy access to a mounting point behind the passenger seat. After marking and drilling out holes, the amp was screwed in place.
Photo 13/17 | Sound Logic Polk Audio System Braiding Speaker Wires | Speaker output wires were run up through a slit in the carpet, braided, and stripped before tightening them into the amp's outputs with a small hex key.
Photo 14/17 | Sound Logic Polk Audio System Connected Amp | With all the wires connected, the amp fit perfectly behind the passenger seat. After turning on the ignition to make sure it was getting power, we moved on to the subwoofer.
Photo 15/17 | Sound Logic Polk Audio System Mounting Sub | Mounting a sub box inside a standard cab truck can be tricky due to limited space. Initially we considered mounting the 10-inch DXi woofer in this MDF box in place of the center bench seat, but it looked awkward and made the sound muddy.
Photo 16/17 | Sound Logic Polk Audio System Custom Subwoofer Box | After a little head-scratching, Audio Innovations owner Joe Provenzano ended up custom-fabricating a box that fit seamlessly inside the center bench seat's foam cushion with the subwoofer facing downward. Not only does it look completely stealthy, it gives the system a healthy dose of thump.
Photo 17/17 | Sound Logic Polk Audio System Head Unit | Here's the head unit we chose to feed our new Polk Audio system, a 6.1-inch touchscreen Pioneer AVIC-D3. With the new head unit, 500-watt amp, four two-way speakers, and a custom-mounted 10-inch sub, our project Silverado sounds truly incredible. The new sound system has crisp highs, thunderous lows, and plenty of power to shake our standard cab Chevy all day long. What more could you ask for?
