Got a question. My ‘88 t-top didn’t come with the performance sound option. I’m not sure if it was available with that option.. my map light “cover” has a hole where the “slider” would be but it looks like it was made to only work with an earlier set up with the three buttos to turn on a light. Is the sub control put somewhere else? Was the map light cover modified to work with the sub system? I can’t find anything about it at all. Thanks for any input.

*I am asking because I want to install the performance sound system and don’t know how the factory did it.

Many T-Top GT's came with the performance sound option. You will need to cut the corners off of the maplight with the slider controls so the trim cover will fit. You will then need to carefully remove the bezel that says "Performance Sound" from the original maplight housing. Now screw the T-top trim cover to the maplight housing and glue that "Performance Sound" bezel to the trim cover. You are done!

So that is how it’s done. Thanks for the info!! I try to keep the interior looking as stock and original as possible, totally ‘80’s
