In recent times Alpine raised the roof as far as custom aftermarket car stereo is concerned, with the unveiling of the Alpine X009-GM. The 9-inch in-dash navigation system was purposely designed for the 2014 and up Chevrolet Silverado 1500 and the GMC Sierra. This radio does not only replace and substantially upgrades the factory unit but offers features not available in any vehicle trim as far as the Chevrolet server auto and the GMC Sierra is concerned.
With that said, Alpine has now announced a new custom speaker Creek kit specially designed and optimized to fit these trucks. If you’re not a fan, you’re going to love both the radio and speaker kits if you’re not even become an Alpine car stereo follower for life.
The new speaker kit part number SPT-31GM is a 3-Way Speaker System designed to fit the 2014-up Chevy Silverado or GMC Sierra (it is not compatible with models equipped with the Bose factory system).
The Alpine engineers must love GM trucks because this kit looks and sounds great. The SPT-31GM transforms the already pretty good sounding truck’s speaker system from a 2-way to a 3-way system using 8-inch woofers for the front doors, 3-inch midrange speakers with 1-inch silk dome tweeters for the dash, and 6.5-inch coaxial speakers for the rear doors.
The speakers and tweeters are custom fit to the trucks factory speaker locations. All the necessary hardware and mounting adapters are included in the kit; this includes custom angled tweeter brackets designed to deliver the best possible sound reproduction regardless of what music you listen to.
The SPT-31GM is not cheap cost wise but then again how much is a factory car audio premium sound system for a GMC Denali? If you like Chevy trucks and you like your music loud and claim this combination of custom fit, custom designed head unit and speaker combination are guaranteed to yield the best performance ever. And in the event, you want a little more punch! Nothing is keeping you from adding an external amplifier, additional subwoofers to the system. The Alpine X009-GM comes with three sets of 4-Volt RCA opening a whole new world to system options.
