The 18T805 was used as premium sound option with the ECU2F type radios, New in 1986, was a new amp design for only the Merkur & Scorpio cars. The amps were 4 channel output. This amp was pretty reliable, unless someone shorted a wire or speaker. With the correct wiring and plug diagrams. Still have a pretty good stock of audio output IC's. Most common issue is a blown 10amp GMA type fuse in the back near speaker output plugs.
