Putting info in the sig helps with what car is this for ...

I think the T/A's have the VSS running through the computer

does VSS even matter if he is running a mechanical TH350?

I'd be concerned an amp in that spot may overheat from lack of air.

I mean to the speedo if it is driven by a VSS. Which I'd assume is gone anyway

Should be fine as long as it's not a huge amp. My last Jeep had a 200w 4 channel and a 100w mono sub amp both shoved under the backseat for years with no issues. Should have about the same amount of room and slightly better circulation under the dash of a 3rd gen.
