6.5 inch round speakers
4x6" in the dash and 4x10" in the rear
I have a 93 roadmaster and I'm trying to put a radiator in, so what size line wrenches do i need to connect the oil cooler
5x7 no bigger no smaller.
The size of the door speakers are 5.25. I have just moments ago replaced mine. This is the dimension of the Concorde is the infinity system.
All four speakers are 4x6. I just ordered new 4x6's for my 93 GMC Sierra, and that is the stock size.
The 93 Camry has 6 1/2 inch front speakers while the rear speakers are 6 x 9.
The door speakers in Geo Prizms From 1993-1997 and possibly newer are 4in. and the rear speakers are 6.5in.
Sell It!!
You can call or go into a GM dealerships service department and they have all the specs on your Roadmaster including the maximum size of rims you can put on without messing up your spedometer..etc.. Hopefully this helps.
The 1993 Nissan front speakers measure 3.5 inches in diameter. The rear speakers measure five inches by four inches. The dashboard speakers measure 2.5 inches in diameter.
The front speakers are 4.75" (yes, a non-standard size) and the rears are 7.0" (you guessed it, another non-standard size). 4.5" aftermarket speakers will fit the front with some additional foam baffling round them to make them air-tight and 5.25" and 6.5" speakers will fit the rear with a Scosche adapter bracket.
