240sx speaker sizes....
 

1989-1993 Fastback
Front- 4x6
Rear- 4x6

1989-1993 Coupe/1994 Convertible
Front- 4x6
Rear- 6.5

1995-1998 Zenki/Kouki
Front- 6.5
Rear- 6.5

These are the stock sizes of the speakers in the 240sx. There are ways to fit bigger speakers into the cars however. Heres a link on how to put bigger speakers in the doors of an s13. For the rear (at least in hatches), if you have a dremel or something similar, you can mount larger speakers in the hatch cover, like this:

s13 240, when u had ur 90` 240sx, what kind of intake did you put on it, a short ram air with a extension for cold air, or just a short ram? im lookin for one, and i have the same exact car as "tara" rest her soul. just wondered if it was a injen, k+m, what kind?

I still have my '90 240sx, Tara is a really good friend of mine who passed away in Jan.

The intake is an OBX short ram intake, I didn't use the OBX filter though, I had a K&N on there before and stuck with that

links and pic dont work, still got them..?

im going to upgrade my speakers soon on my fastback, so i'd REALLY like to know what i can do before i drop money on something ill replace in a week...

I'll try to find it again.

i also would like the links please i have garbage in there now.. lol

**edit: Ok, basically here is what you will need to do to fit bigger speakers in the front of the s13**

Step by step front 6.5" setup:

1. Take off your door panel.
2. There should be a black plastic enclosure in which the stock 4x6 fits, remove it.
3. In 1/4" plywood (or whichever material you use) trace that enclosure with drill holes AND speaker hole.
4. Cut the speaker hole and plywood.
5. Replace the black plastic enclosure with the plywood part you just created.
6. Connect and mount you 6.5" speaker on the plywood.
7. Turn on your radio to check if the speaker works properly.
8. Make sure window still functions properly and is not hitting the speaker or wires
9. Pop door panel back into place.

should look something like this when done:

That looks like a pice of art well done!!!! I will try it and see if I can do it.

some1 sticky this good stuff, i will do this with my new dremel tool score! good post as always my friend.

edit: what thickness of plywood????

Does anyone on this forum have 6x9's in the trunk of their s13? if so please post up some pics and state if there were any problems with it etc.. thanks.

S14 Note
 

FWIW, the S14 speaker sizes are technically 6.75" or "oversize" 6-1/2's

Certain brands of 6-1/2 will work, but the best fit is with 6-3/4

I just did custom 6x9's in the side panel of my s13. I can get pics in a few days (I'll be out of town until Tuesday) if anybody wants them. They sound so nice where I have them. Great bass.

hey s13 240... what tool did you use to cut the hole in your rear hatch cover? im gonna put my alpine 4x6's back there cuz finding speakers that fit factory locations is a ho. damn nissan's funky speaker locations!

haha, when I did that I used a drill and a handsaw, took forever to do it that way and make it look decent. I'm gonna do it again but this time using a dremel which should make it a hell of alot easier.
