Giveaway: rear speakers from '94 Civic Si (Hatch back)
 

I got an incredible deal on a pair of refurbished Sony speakers, so I
now have a pair of stock 5 1/4" speakers from my '94 Civic Si that need
a good home. These are the ones that go in the side panels in the rear.
The Honda part number is 39120-SR0-A01. The speakers will definitely fit
'94 and '95 Si. Honda EPC does not show rear speakers in '92 or '93 Si
or in CX, DX or VX for any year It looks like you need both a bracket
and a new inner panel to fit rear speakers in these cars.

Regardless, these speakers can be yours for the cost of shipping.
