The 1998/1999 GRX
actually has 6.5" speakers in each of the four doors. They are Clarion 4 Ohm dual cone units that are rated at 30W (peak) and 15W (nominal). The problem with these speakers is that the diaphragm that supports and centers the main cone perishes with age, leaving the cones unsupported and the armature free to touch the coil. This leads to horrible sound distortion at all but the lowest volumes.
The parts manual does show that some models have 5.5"/6" speakers (possibly the GLs?).
When I opened up my passenger side front door recently to fix the central locking (see here
), I decided to replace my old knackered speakers as well. I bought four two way 6.5" Kenwood speakers (30W nominal rating). Although the Patrol's speakers are 6.5" units, the pitch circle diameter of the mounting holes is just a tiny bit smaller than that of the aftermarket speakers, but the speakers still fit with a bit of fiddling and gentle persuasion. The sound quality is quite good, but is definitely not in the professional audiophile league. Then again, that was not what I was after...
