Hopefully someone can help. I have a 1993 Ls400 with a (stock) pioneer radio w/cassette player. no cd or cd changer. I would like to put a different radio in there, but i do not know if the amp is built in the head unit or if it somewhere else in the car. Do i have to install an additional amp if my new head unit does not have a built in amp? where is the best location to install an amp?

Also, i just changed the the antenna mast and i noticed, where the signal wire plugs in, there is also an additional plug- that looks like a coaxial next to it that is not plugged into anything. what is that (for)? Thanks for your help.

It has a built in amp for the door speakers and a separate amp for the sub.

The coax cable was for an optional dealer installed phone. There were two different phone systems available in 1993 - fixed and portable. The other end of the coax is above the headliner at the center top of the rear window. You can see it if you take a peek.
