will 6X9's fit in e36
Can the stock e36 rear speakers be easily replaced with a pair of 6X9's ?
I don't want to do any cutting, but don't mind drilling for mounting screws.

If you DON'T wanna do any modifications than NO it will NOT fit!

5-1/4" are the only size that fits!

Justin e36 05-21-2006 02:32 PM

if you don't mine drilling / mounting screws + nuts, then yes it fits no problem.

I've seen adapters, or you can easily make adapters out of MDF for the parcel tray.

I don't mind drilling, but do not want to cut anything. (in case I want to return to stock)

Sounds possible. Thanks for the reponses.

Maybe just a single 10" that I have kicking around. Not really looking for a bass machine, but nice clear sound.

paul christians 05-25-2006 06:38 AM

has anyone done this before, and are there any sites that explain how to? Because I have a pair of 6x9's infinity kappa's that I would love to use rather than have them sitting around in my garage.

Justin e36 06-07-2006 01:29 PM

Infinity Kappa? Yummy... some of my favorite car audio speakers of all time.

How do it is fairly simple.

1. Remove your stock speaker boxes
2. Trace the shape of the box onto the MDF. Cut it out.
3. Mark the mounting screws for the stock box. Drill those holes out.
4. Trace the shape of your 6x9's in the middle of the cutout, along with the mounting screw holes.
5. Cut out the hole for the 6x9's, and drill out the screw holes.
6. Screw (nut & bolt?) the 6x9's to your MDF bracket.
7. Mount the bracket w/ speaker to your rear shelf.

This will make a free-air bracket. If you have subwoofers in your trunk it's advised to keep your rear speakers in a box to allow them to play in a separate airspace. Also test the excursion of your speakers to make sure it won't hit the bracket. The thickness of the MDF can act as a buffer to space out the speaker cone from hitting the rear deck under extreme use.

Here's what a store-bought adapter looks like:

if ur gonna have a sub, dont bother replacing any speakers unless they are really ****ed up and the cones are ripped. i got a 10"sub in thursdays and my deck has a featuer where i can turn off the base to the speakers and make it only go to the sub. this way the speakers produce only highs which even for old speakers is easy.

Even if you don't have a sub in the trunk, is there any advantage to placing 6x9's into an mdf enclosure when mounted under the deck. Will it improve sound at all?

Justin e36 12-03-2006 07:48 AM

Yes definitely helps to put it in a sealed enclosure---the back pressure will help tune the sound of the speaker, and will help reduce excessive vibrations which cause distortion, and can cause the surround to rip eventually.
