hi just planning ahead (sell waiting for mortgage) what size speakers fit in the front of a 300 got some 6" at home had 3 cars ago wont fit any others cheers jay

Also what size are the rears? Sorry for the thread hi jack mate :p

The rears are 6X4 mate, dont know about the fronts, I have 6X9 in the front of mine.

I just fitted some infinity referance 6.5" components in the front of my car, altho they were slightly big and i had to remove the bracket from the door and do some slight mods, not a massive job tho, and sound soooooo much better than the stock speakers, I would have thought 6" would be a more or less direct fit, nissan use 3 hole mounting tho, and its usually 4 so you might have to re drill holes.

 

as for the rears mine already had some JBL 4x6's fitted in a proper adaptor bracket, not sure what the originals would have been

I have some £20 ebay Alpine 6x4's in the rear. Problem is with non factory ones (which are awfull) is that the mounting holes are off. But i was happy to mount mine with two per speaker holes across a diagonal.

thanks cant wait till i can get a z mrtgage taking forever noone wants my bmw
