Alpine PSS-31GM Direct-Fit Amplified Sound System For Select 2014-Up GM Trucks
Alpine 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.
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.
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.
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.
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.
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.
