Has anyone replaced the rear door speakers on their '05 Sedan. Needed to know if they need the 1" spacers like the fronts. Thanks!!

 

Anyone?????????

 

Yep, use the same spacers. Infinity uses the same speakers front and rear. The only difference is that the rears do not have a seperate tweeter.

 

The '05 sedan rear speaker is exactly like the front in that the speaker/spacer is one piece.

What I did was cut/break the old speaker out of the spacer (with a plier) and put the new speaker in place of the old speaker. And then used the 4 screws to secure it.

I was able to install the Infinity Kappas in the rear using this method. So you don't really need to buy new spacers. Plus, they fit better since the new 1 inch spacer would leave a small hole in the door.

 

is this the same for the coupe too?? 03 coupe

 

same spacers, but the rears do have a little more clearance if you have a very low profile speaker, you may not need spacers

 

How much better did your system sound with these. I am assuming you had the stock head unit, with or without the bose. Let us know. I hate the factory system and cant put the cash toward the whole head unit/ac controller deal Thanks
Plus what were the exact model speakers you got, and about how much are they?

 

I've had the pleasure of owning a 2004 Coupe, and now a 2005 Sedan and I've done some serious re-work of the stereo system in both vehciles, here's my two cents...

The rear speakers in the coupe are the same as the front, but the paneling behind the speakers (solid panel) does not allow for a very deep speaker. I used a hammer and smashed in the paneling to fit my Infinity Kappas. You can create a spacer, but it still won't work unless you trim down the inside of the rear quarter panel... there's just simply not a lot of room. I recommend running a shallow speaker. P.S. The speaker location is CRAP too... you can't hear it that well as the front seats block any direct sound, and it's almost a waste in the coupe. I removed the rear deck 6x9s for a port from my trunk to let the bass in and WOW, that made a difference.

As for the sedan, then rear doors are EXACT matches to the front, and the speakers fit in just fine. The rear are just a little harder to work in, being that the pillar is in the way and the door is a little less accessible for custom work. I made MDF rings for spacers front and back and they worked like a charm. I used the 5/8" mdf for mine. Just thought that the 3/4" was too bulky and would have made it REALLY close.

I've got pics if you need them, might be useful. Good Luck.

 

the most important thing IMO is that you make sure the foam ring around the speaker grill in the door is making a good seal with the front of your speaker. This is how you get good sound. You want the foam to still touch and seal correctly. Many people do not take the care to do this because they don't know what kind of effect it has on the sound.

 

Is there a big - noticable difference with these speakers, if you retain the factory head unit?

 

It's a HUGE difference. I wish you could hear my car. I kept the factory deck, put a David Navone converter on it, and now run a whole new series of Alpine Amps, Alpine 12" sub, and Infinity Kappa speakers. UNBELIEVEABLE SOUND.

 

Joes954, now you got me interested. Where did you put the sub? What amp did you get, (model and watts). Were you by chance able to get a IPod hooked up to it?? Thanks for the info.

 

I'm working on getting my iPod video installed, but just for the music part (not the video).

I run the V12 Alpine amps, pushing about 500W-700W to the Type R 12" sub, and roughly 75W to each door. LOVE the sound. I am also running the 4080 subwoofer encolsure (right hear from G35Driver.com) and can't begin to explain how incredible this box is. Just looks killer, built killer, and sounds awesome. No screws to install, just fits as snug as you could imagine. AWESOME.

Here's some pics of my ride if your interested, PM me for any other questions. I have a TON more pics at home.

 

You can actually tell a difference in the bass the sub is producing with the 6x9s out, rather than in? I heard most people just disconnect them alltogether, but never thought of removing them to help the sub.

 

If they were simply disconnected, it seems like they would effectively act like passive radiators from the trunk to the cabin.
