I have a 2003 WRX sedan. From some reading around, the OEM fronts are 5.25" and the rears are 4". One of my rear speakers isnt working anymore and my friend has a pair of OEM 5.25" speakers (from his suby) lying around. will i be able to just drop in the OEM 5.25 into the rear or will it require a custom spacer (ie., those offered by iaperformance)? i'm just looking to replace the broken speaker with whatever is lying around (free). figure i can do this over the weekend when im bored, but will need to know if it'll fit or not. if i have to buy a custom spacer just to fit the OEM front 5.25 into the 4" rear, then i guess i'll go on with life on 3 OEM speakers.

thanks in advance!

 

Where is Rosemead? I have a pair of OEM rears that you can have. The fronts might fit with slight modifications, but they are a midrange only, so no tweeter I believe.

 

Rosemead is about 10-15mins east of downtown Los Angeles........

 

The front speaker is a 6-6.5 inch but is very shallow. Most people simply trace the stock speaker outline onto a peice of 1/2" or 3/4" MDF or other material and cut out a speaker adapter that will bolt into the factory hole and give you enough clearance to mount a more robust driver. The rear is an odd 5" size that most people replace with a good 4" or not at all. I know many people with really good front speakers and some type of sub and no rear speakers at all. I prefer a strong front stage.

There have also been several vendors over the years that have made custom speaker reings as i discussed above if you don't want to make your own and generic round speaker rings can also be used but require drilling new holes into the doors sheet metal.

Cheers

 

This thread is almost a year old, I'm sure he got it figured out by now.
