Alpine's big-time upgrade for your GM truck

How great would it be if someone took the guesswork out of installation and offered a top-notch speaker system perfectly suited for your GM truck? Well, Alpine's done it. Their phenomenal Restyle line, which started with custom-fit navigation receivers, now includes "everything-you-need" sound systems. Upgrading the audio in your GM truck just got a heck of a lot simpler.

Deluxe sound

Alpine's PSS-31GM speaker system gives you an impressive speaker system that requires no custom installation work at all. Thanks to special brackets that adapt the included 8" woofers to fit your 6"x9" factory door locations, you'll gain an especially powerful 3-way component system for your front doors. The 3" polypropylene midrange drivers fit into factory door locations, and Alpine includes two speaker pods loaded with 1" silk dome tweeters for superior highs. A pair of 6-1/2" full-range polypropylene-mica speakers fit into the rear doors.

The package also adds a custom-fit, space-saving 10" sub that delivers strong low-frequency punch, and a 5-channel amplifier that powers all the speakers. This system will really rock, whether you're using the original GM radio or an aftermarket car stereo.

Blend it in

Alpine designed the Restyle line for drivers who want to improve their sound while maintaining the factory look of their vehicle. The PSS-31GM system upholds this approach by giving you streamlined tweeter housings that match the style of your GM interior. Mounting brackets are also included for fitting the system's speakers into the factory speaker locations and using the factory grilles. The direct-fit sub enclosure is perfectly tuned to your pickup and designed for installation behind the rearmost seats. Once the PSS-31GM system goes in, you won't even know it's there... until you crank up the volume.

Features

Overview: Part of Alpine's Restyle speaker line, the PSS-31GM sound system upgrade kit is designed for select 2014 and up Chevrolet Silverado and GMC Sierra trucks (Double Cab and Crew Cab models only, not compatible with factory Bose systems). The package includes 6-1/2" coaxial speakers for the rear doors, 8" woofers for the front doors, 3" midranges and 1" tweeters for the dash location, and a 10" Zero Space subwoofer that gets mounted to the rear wall, all driven from an Alpine MRV-M500 5-channel amplifier.

Wiring: The PSS-31GM system includes a T-harness that plugs in between the factory wiring and the factory radio or aftermarket radio adapter, providing a connection to the factory speaker wires. A 17' extension from the T-harness gets run to the Alpine amp providing the speaker return lines back to the factory wiring in the dash along with a remote turn-on wire. A pre-formed set of 6 RCA cables provides the signal from the radio to the Alpine amp. If installing with a factory radio, a 10-pin pigtail at the radio end of the T-harness provides the speaker level signals to run to a line converter (sold separately), and then to the RCA lines back to the amp. Each speaker location includes a wiring adapter to interface the factory wiring to the speakers. A separate 3.5' section of 14 ga. speaker wire is included to run from the amp to the subwoofer. The amp wiring kit includes a 4 ga. power wire with an inline fuse holder, that gets run to the battery, and a 4 ga. ground wire for powering the amp.

Note: If installing the PSS-31GM with a factory radio, a line output converter and a pair of RCA Y-adapters will be required, or 4 pairs of speaker extension wire will need to be run from dash to the amplifier's speaker-level inputs!

Door Woofers: Included for the front doors are a pair of Alpine SPT-80W woofers that are part of the 3-way speaker system for the front of the vehicle, providing punchy solid bass. Wiring adapter harnesses, for adapting into the factory wiring, are provided along with inline low-pass crossovers. Mounting brackets and hardware are included for installation.

Dash Midrange/Tweeters: The PSS-31GM speaker kit includes a pair of SPT-30M 3" midrange drivers and SPT-10T 1" silk dome tweeters for the dash location. The included ALP-31GM-POD tweeter pods are designed to relocate the new tweeters from the "A" pillars to the dash, as well as provide a new speaker grill for the mid-drivers, which re-use the factory location. The tweeter pod's shape and mounting location are optimized for the best sound imaging and clarity. Crossovers, for both the mid-drivers and tweeters, are provided along with speaker wiring harnesses that adapt directly into the factory wiring. A template is also included for installing the tweeter pods on top of the factory mid-speaker grills.

Note: Drilling and cutting the factory grill is required for installation!

Rear Doors: A pair of SPT-70, 6-1/2", 2-way speakers are provided for the rear door location. These also include their own mounting brackets along with wiring harnesses to adapt directly to the factory wiring.

Amplifier: Power for the speakers is provided by the included Alpine MRV-V500 5-channel amplifier. This Class D digital amp is part of the 4th generation of V-Power amplifiers with 80% efficiency and reliable performance, all in a compact chassis. The included amp wiring kit provides 4 ga. power and ground wires along with a 6-channel RCA cable assembly for running to the amp. A bracket and hardware is included to mount the amp to the back wall underneath the rear window.

  • Power Output:
    • 4Ω: 40 watts x 4 channels + 150 watts x 1 channel (<0.07% THD+N)
    • 2Ω: 60 watts x 4 channels + 250 watts x 1 channel (<0.09% THD+N)
  • Signal to Noise Ratio: 81 dBA (1W into 4 ohms)
  • Bridgeable: Both the front and rear sections of the MRV-V500 are bridgeable, allowing the amplifier to be used as a 5-channel, 4-channel, or 3-channel amp.
  • Speaker Level Input: A speaker level input harness is included, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs. The 8-pin harness has inputs for front and rear speakers.
  • Auto Turn-on: If using the speaker level input, an automatic circuit turns the amplifier on when it senses an input signal.
  • Controls: The front, rear, and subwoofer sections of the amplifier (labeled CH 1/2, CH 3/4, and Sub W.) have independent gain and crossover controls. The subwoofer channel also adds a Bass EQ switch:
    • CH 1/2:
      • Gain: rotary dial; continuously variable from 200mV-4V using the preamp inputs or 500mV-10V using the speaker level inputs
      • High Pass Filter: On/Off
      • Crossover Frequency: rotary dial; variable from 50 Hz to 400 Hz
    • CH 3/4:
      • Gain: rotary dial; continuously variable from 200mV-4V using the preamp inputs or 500mV-10V using the speaker level inputs
      • High Pass Filter: On/Off
      • Crossover Frequency: rotary dial; variable from 50 Hz to 400 Hz
    • Sub W:
      • Gain: rotary dial; continuously variable from 200mV-4V using the preamp inputs or 500mV-10V using the speaker level inputs
      • Low Pass Filter: rotary dial; variable from 50 Hz to 400 Hz
      • Bass EQ: rotary dial; variable from 0-12dB; boost centered at 50 Hz
  • Connections:
    • Battery: set screw terminal; accepts up to 4 gauge wire
    • Remote: set screw terminal; accepts up to 8 gauge wire
    • GND (ground): set screw terminal; accepts up to 4 gauge wire
    • Speaker Outputs: 5 pairs of set screw terminals; accept up to 10 gauge wire
    • Line Inputs: 3 pairs of stereo RCA jacks
    • Speaker Level Input: Molex plug input for supplied 8-pin harness

Subwoofer: Included with the PSS-31GM speaker kit is Alpine's 10 inch Zero Space Subwoofer in an assembly that comes with a specifically tuned enclosure for select 2014-up Silverado and Sierra trucks. The subwoofer assembly attaches to the back wall behind the rear seat so it doesn't take up any usable space under a seat. It's tuned for deep bass and creates low-frequency extension by coupling the enclosure to the cabin vents behind the seat.

Note: Minor drilling and modifications to the rear vent are required for subwoofer installation. Also, a rivet tool (not included) is required for this phase of the install.

Q
Will a capacitor be needed when a.c. night high output demands?

Don't think so. Its preformed well the whole time I've had it. I do have a diesel with two batteries. So that may make a difference. But it's only 350 rms 5 channel so sub only uses 150rms.

If your truck's alternator does not offer enough amperage for the Alpine amp, you may need to upgrade the electrical system: https://www.crutchfield.com/learn/learningcenter/car/stereo_power_ups.html?search=headlight For additional assistance and personalized recommendations, feel free to contact us directly by phone or through our online chat service: https://www.crutchfield.com/support/ContactUs.aspx

Q
Crutchfield says this will work with factory Bose system while everywhere else says not compatible. Does this work with the Bose system?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
