Your factory or aftermarket car stereo can get the sound system upgrade it needs in one package. This 310-watt system consists of the SPT-31GM 3-way component direct-fit speaker system, an MRV-V500 5-channel V-Power amplifier and Alpine's unique 10-inch zero space subwoofer. The SPT-31GM upgrades your truck's speaker system from a 2-way to a 3-way system. It consists of 8-inch woofers (for the front doors), 6.5-inch coaxial speakers (for the rear doors) and 3-inch midrange speakers with 1-inch silk dome tweeters (installed in the dash). Unique tweeter housings embossed with the Alpine logo protect the midrange speakers and tweeters on the dash and are optimized for the best sound imaging and clarity. The speakers and tweeters fit into the factory locations and use the factory connectors for incredible imaging and staging in your truck. All needed installation hardware like amplifier wiring and speaker adapters are included (some vehicles may require custom tweeter installation). The SPT-31GM may also be purchased as a stand alone speaker system.


The subwoofer assembly comes with a specifically tuned enclosure for the select 2014-up Silverado or Sierra. It attaches to the back wall behind the rear seat in the truck 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. Rounding out the system is an MRV-V500 5-channel V-Power amplifier. Don t let the MRV-V500 s small size fool you. This 310-watt amplifier produces clean, efficient power even during extreme power demands.
