1986 LeBaron convertible, 2.2L T2 with A413. 1989 J convertible dash and console modified to fit.
It would be in the trunk according to my AllData. It amplified the door and rear speaker circuits, dash speakers were not amplified. I am doing a similar upgrade to my 1986. It used the older Infinty Speaker mounted amps and trying to find 4 good ones is mission impossible. I salvaged a system, less speakers, from a 2001 Sebring convertible, it is a full 6 channel amp with a top down equalizer mode.
