e36 rear deck speakers

So the factory ones are 4-inch with a 1-inch tweeter next to it in that black nokia-stickered black plastic enclosure. I'm thinking of trying to fit a 5.25 in there.

Does that box allow for trimming the opening to accomodate the 5.25? Should I even bother trying or just go with a 4-inch coaxial/component set?

There are many options available for the rear deck, you can fit a 5.25" back there easily, I believe ChalzBmr has done this with a custom enclosure. There are also brackets available for 6x9's, and custom enclosures for a 5.25" and have ports on the side for moving air from the trunk into the cabin.. (for your subs).

You really do know your options on this car!! Wicked.

Accoustically, 6x9s suck.

So a 5.25 wont fit in that OEM enclosure even with some trimming, huh?

If I was to go custom enclosure, then it would be the 5.25 option. Tell me more about this custom enclosure with ports on the side option... I have an alpine monoblock feeding some 10s that were way louder in my last car

yes 6x9 do suck, you can go with 1 of 2 setup here (1) 5.25 or (2) 6" in the rear. With some work but no big deal in it.....

Yup, my personal preference is a 5.25 + port. Right now I have the upgraded baffle boxes in my rear deck from a 98 318is convertible... a nice stock upgrade, considering it was a free.

If you do want 6x9's, you just have to make a basic adapter plate out of wood.. very simple, here's an example:



or you can buy a plastic one if you have money to burn:



This is the adapter plate you want though, 5.25 + 1" tweet.



I can't find the 5.25" enclosure with an air pass-through port, I had a link to it somewhere in this forum, but I can't find it now. I believe it was available through cruchfield.com

Your other option is just ot get the adpater plate above, use a 5.25 two-way, and leave the tweeter open, or add a PVC tube pass through to your subwoofer box.

Remember that if you do have subs in the back, you're going to want your rear deck speakers to have their own enclosure to keep their air-space separate, otherwise they will sound distorted everytime the subwoofer thumps and forces the speakers to move up from the shared air space, especially if you have a ported box that isn't only pushing air, but sucking too.

hope this helps.
