for those with the stock 6-speaker non-jbl system who's thinking of upgrading your rear speakers, don't do it. :thumbsdow i'm too far into it to stop now and already purchased the replacements (5.25 Hertz coax) along with the already installed 5-channel amp. :headbang:

basically, you have about 2.5 inches of dept at best to work with and one mounting hole. the stock speaker is a joke. size is weird. it's about 6" in diameter with a quarter size magnet and really, really shallow. i have to do some custom work to get my replacements to fit. i'm going to mod the existing grill and just lay speaker grill fabric over it. hope this works out. :disappoin

Hello rob. Can you post instructions on the rear speaker panel removal? Is it just removing the speaker grill or does all the panels in the rear have to come out? I'm thinking of putting infinity components in the factory locations and mod the grills like you. Keep us update on your project. TIA!

the speaker grill is removable but only from the back. you have to remove the floor panel that runs along the sliding door, then work on the panel with the grill. it's just a bunch of nylon type tabs that holds everything down. the panel with the grill doesn't have to be removed completely. you just need to pop the edge near the door opening to access it.

i also replaced my front door 6x9 and factory tweeter with a set of 6.5" hertz components. that part was easy compared to the rear. :thumbsup:

thanks! i think it's going to be ok... i ended up cutting a hole on the stock grill and built a ring for the speaker to mount on. i'm going to get a shop i know shoot some fiberglass on the ring/exterior of the grill to create a small bulge, sand it down and bondo if needed. i'll cover it with fabric to finish the look. it's not going to look stock, but it'll be decent *crosses-fingers*. good thing about the rear speaker placement is it's usually covered by the middle row seats. :D

i though about finding a shallower speaker but mounting will still be an issue. using the stock ring is not even an option because of the design of the stock speaker. there's no room to work behind because it's pretty much against the metal. i dynamated the area which only made things worst. :eek:

but if anyone is up to the task, it's certainly doable but it's not a drop-in speaker to say the least. :facepalm:

...1st post you said don't do it

finished last night and pretty happy with the result. sorry, i didn't take pics of the process. :( i'll take pics of the finish product after i clean the mess i made. sound quality of the speaker upgrade is definitely worth all the hassle. :thumbsup:
...last post "worth all the hassle..."

:confused: :confused:??

Do you think it is because the sub/amp you add that made the different in sounds rather than the speaker upgrade alone?

From my experience (on recent Toyota, not old cars), speaker upgrade alone didn't really give you much.

Aside from the non-drop in issue, I didn't hear a difference with the rear speakers. I faded the speakers to the fronts and then with the fronts+rears and can barely hear them at all.

Partly b/c it's covered by the 2nd row seatings and they're usually fillers, I didn't bother replacing them.

gs3tek, are you running an amp and subs?

my main reason for upgrading the rears was to provide the 3rd row with better sound than what the stock was providing. it's also hard to hear the mids from the 3rd row. after the upgrade, the sound when sitting in the back is much more complete with my 10" sub in the rear. it was actually too loud for my taste so i turned the fader to the from up +5 (+15 being max) to balance the sound for the entire cabin.

Looks good Rob:thumbsup:

I did initially for the amp, no subs.
I was going to use 6.5" mb quart components up front but stopped b/c I got a little lazy and just went with the 6x9 pioneer coax. Provided plenty of mid bass and highs (but not bright, of course).

Plus I was going to use that components in another vehicle instead.

Here's a tweeter that I installed on the passenger front. It's not hooked up though.
I'll have to take it out and probably wrapped that in CF to cover it up:D

np.. the ring i built had to be installed in an angle to get the speaker to mount right so the back end sticks out further because of the panel's angle. if you look at your grill, the speaker is not centered. the hole si more towards the door which only made things harder because you had less room in the back.

I just finished my install on my se, focal polyglass 165v30 upfront and morel coax in rear, pioneer avh-4200dvd with steering wheel control and xm. also running one jl 12w3, all off jl amps. all wires tucked, only one slice in factory harness ( for steering wheel control), used existing xm antenna going into my xm module with adapter. Rears were a bitch, managed to have everything fix without modifying the speaker grills. Cut out the rear speaker material and modified the speaker basket to house the new coax. Car sounds amazing. We sould have a SoCal meet up. Pix will be up this weekend.

Rob.
Can you hear your pioneer sub in the trunk? Does it fit between the second and third row on the driver side? My three year old could use it as a step stool to get into her car seat.

the sub can be heard while in the trunk area. the bass output on the pioneer sub is pretty nice. i'm sure it'll only get better after it loosens up. the sub does fit between 2nd & 3rd row easily and i'm also considering this idea as well for the same reason. the enclosure design of this box is perfect for this. it can withstand pleanty of weight. initially, i wanted to stick it under the 3rd row but the brakets hanging down is going to prevent that from happening. i also tested it in the 8th seat storage area and fits nicely. :thumbsup:
