Mach amp, part# F7DF-18C851-LA, and a set of G3 mach tweeters for sale. Will be tested today. Tweeters include the crossovers, plug, and about 2 inches of wire. Pics to follow. Send a PM or post here if interested. Want to see them go as a set unless 2 people can callaborate and seperate.Tweeters won't mount correctly in a G4, but the RCU is a direct swap.
