Firebird factory subwoofer system NICE!!!
Firebird factory subwoofer system. These sytems were a very rare option on 84-88 cars and most people don't even know they exist. The system consists of two ported boxes that mount in place of the rear 6x9's. These boxes hold a 4x6 inch speaker along with a subwoofer. It also has a dash mounted on/off switch with a gain control. This system also includes the wiring, amp, and stereo faceplate with the "Performance Sound" badge. These systems are very hard to find and even harder to find with good subwoofers because the factory subs tend to deteriorate around around the edges. These have replacement subs with rubber surrounds so they work great. Don't miss out on this chance to buy this very hard to find system. $150
