Hey, I just got a '90 240 and after much frustration I rewired the wiring harness that the previous owner hacked to death to get my Kenwood KDC-519 in there. Anyway, I turned on the system and not suprisingly it had some of the ****tiest speakers I've ever heard. I took the door panels off and found a set of DEI Studio (seriously old school) aftermarket component speaker setups in there. I was wondering what size speakers can possibly fit in there to replace em. I've got some 6" JL TR600-CXs in my Honda that i'm thinking of swapping in there if they'll fit. But other then getting more components to fill the hole I was wondering if like some 4x6s or 5x7s would fit in there. If anyone could help thatd be great.

 

All of the ones you have will fit.
The 6" will need work. Other than that, go for it.

 

Hey I just got a 1990 240SX and was also looking to upgrade my speakers to a little better then stock. And thus far I have found that the sizes are as following

Front Door: 4"x6"
Rear Deck: 6-3/4"

Saloon

"Racing: Because baseball, basketball, football, and golf only requires one ball!...and soccer well......we all know about soccer ;-)

1993 Mitsubishi Eclipse GSX
1990 Nissan 240SX

 

Only coupes are 6 3/4" in the rear, hatches are 4x6.

 

thanks for the help

 

i just put boston 6 1/2 speakers in the front of my 90 hatch. Dont get 4X6 or 5X7 neither will compare with coaxile or component circle speakers. My bostons are awsome

 

if u want to be 100% sure about what will fit in there stock and what wont....go to www.crutchfield.com

 

i wonder if 5 1/4 will fit up front.. my speakers are crappppppyy

 

im my hatch i put some pioneer 4x6 in rear and SPL 4x6 in the doors....sounds way too mid/hi range but atleast i have music. i can have a box sliding around in my hatch...
so atleast i hve music

 

I had those same Pioneers in my old 240. Pretty damn good considering I got all 4 for $75, but I know what you mean they don't do low frequencies too well. The Alpine 4x6's I have now though, do pretty good with bass.

 

those are the same speakers i looked at today .. but they are 50 a pair.. but they will do i think.. i dont really care about having the best sound system..

 

I have MB Quart 4X6s front and rear. They work great, excellent quality.

 

I have a 92 coup and i have those same pinoeers in the doors, and I have pioneer 6.5's in the back

 

it sucks how 240's come with that plastice mount for 4x6 speakers, i just removed it and used a piece of would cut to the same size as the platice thing and mounted 6 1/2 bostons up front, they can produce noice that not even the highest end 4x6 could. I have 6X9's and 2 12's my system is one of the best i ever heard because i have great high in the front, great high's and mids from the 6X9's and great bass from my subs. Do not just buy what speaker will fit in a stock 240, becuase our cars are so easily costomized that any speaker size could fit anywhere in this car. I have my 6x9's mounted in the cieling right above the back seet. THe angle of the ceeling points them forward a little and the sound is amazing. think outside the box.

 

wut brand are u speakers?
