The Alpine PSS-21GM 2-Way Direct Fit Sound System upgrades your truck's sound system while using the factory speaker locations. It is compatible with your factory or aftermarket car stereo as long as you don't have the Bose factory sound system. This kit includes 6.5" speakers for the front doors, 6.5" coaxial speakers for the rear doors, 1" pod-mounted silk dome tweeters, a MRV-V500 5-channel V-Power amplifier, and a 10" zero space subwoofer. Unique tweeter housings are optimized for the best sound imaging and clarity. The speakers and tweeters fit into the factory locations and use the factory connectors. The 10" zero space subwoofer doesn't take up any usable space as it attaches to the back wall behind the rear seat. It is tuned for deep bass and creates low-frequency extension by coupling the enclosure to the cabin vents behind the seat. The 240W amplifier produces clean, efficient power even during extreme power demands. This system is backed by Alpine's one-year warranty.
