Default Rear door speaker install photos

veloLexus inspired me to dig these out and post them. Each is resized/compressed to fit under 50k, but (oh great Moderators) if the total space (or usefulness!) is a problem, let me know and I'll try to find someplace to post them on a different server.

These are photos of my rear door install (these are all of right rear door) of DEI Studio 3045s (4" 'woofer' + neo tweeter) in place of stock (non-upgraded) speakers on MY02 OBS. I next plan to dynamat (or equiv) the openings that you can see in the inside metal door panel.

Hopefully, some of these will help out people thinking about changing their rear door speaker setup.

Photo 1: Stock door panel, removed. Note cavity under armrest suitable for mounting crossover.

Photo 6: DEI 4" 'woofer' mounted in stock mounting ring. Note 3 pairs of holes on outside; one from each pair is used to screw the stock ring to the door (see later photos). The 4" DEI was almost too small for this mounting ring (hence people reporting they fit 5 1/4" speakers in back, with some enlargement of the door's metal opening); I used the sticky foam gasket that came with the speaker to bridge the gap between inner edge of mounting ring and outer edge of speaker. I also had to dig up some washers for the 4 inner mounting screws to make sure all 4 tabs of the DEI speaker were held down securely. See next photo for back view of this.

Photo 7: Back view of DEI 4" woofer mounted in stock mounting ring. Note protective rain/water shield extending out from back of mounting ring almost 270 degrees around. Note also thin strip of foam outside this shield to fill any gaps between door metal and speaker mount.

Photo 8: Closeup of speaker mount opening in rear door, with the 3 screw points circled. (The black circular pad inside the opening, glued to the outer metal panel is Cascade Audio 5" Deflex) You can also see the stock location of the OEM speaker wire.

Photo 9: 4" DEI woofer installed in door. OEM speaker wire has been pulled out and rerouted throug slit in clear plastic, facing toward back (it will plug into short pigtail with matching connector coming out of crossover mounted in door panel). Woofer wires were routed through same metal hole as OEM speaker wire, and out same slit in plastic. Disconnects were soldered on the ends, and these will plug into short pigtail with matching disconnects from woofer side of crossover.

Photo 10: View of inside of door panel with pigtails attached to crossover (see photo 9 for pigtail info). Photo 11 has closeup view of crossover and pigtails. Foam tape was wrapped around middle of tweeter wires to prevent rattling noises.

Great pics, gives me a few ideas. Thanks for posting them. Does the spray on vibration damper make a big difference. I'd like to quiet down the WRX a little bit but I thought it would be a chore. A spray on would certainly be easy and if it made a big difference I'd pull the rear door panels off as well while I'm doing the front speaker install. Did you do anything to waterproof the crossover and what's "Marine Goop"? I'm assuming I can get it at a marine store .

Thanks, Joe

Great info and pix. Now I can get going on my rear speakers project with all of this information.

Thanks.

veloLexus,

I only used the spray-on damper because I was concerned that the relatively lightweight plastic of the woofer grille/tweeter mount area might rattle (and the spray-on was fairly cheap -- looks like 1-2 cans for two coats on all four doors). I don't think the spray-on will do anything for general noise from the outside, especially after seeing the big size of the openings in the inner metal door panel! I'm going to put dynamat equivalent (VB-2) all over that inner metal door, in place of the clear plastic liner, to try to cut down on that noise.

I thought about waterproofing the crossover, but thought that not blocking its air vents was important, too. Besides, (a) it's sheltered a bit under the armrest indentation and (b) it's on the "dry" side of the clear plastic line (or VB-2 once I get that installed).

Finally, adhesives were surprisingly a major decision. It turns out that epoxies do not do that well at cold temps (under freezing), and since I'm living near the ice belt, I figured I'd avoid that. www.thistothat.com gives a fair amount of useful advice about how to glue "this to that". They recommend the "Goop" brand of solvent-based silicone adhesives as really good stuff.
For the crossover to plastic door panel mounting I chose Marine Goop. According to the package for "Marine Goop" (oriented slightly more toward wet/damp uses), once dry/cured it can handle -40F to +150F temp, and it's waterproof and slightly flexible (thus the crossover won't suddenly "snap" off of rigid dried adhesive due to shock or slight temp-caused size changes). Since the door panel was slightly curved, I just made a big puddle of way too much goop and plopped the crossover down into, pressing it hard against the armrest corner.

To attach the rubbery Deflex disks to the outer metal door panel, I chose Permatex "Pit Crew's Choice Adhesive & Sealant" which is designed to reattach loose trim as a contact adhesive. I spread some out on the metal door panel and "rotated" the Deflex disk onto it. Supposed to be non-toxic; milky white but dries clear.

I bought the Marine Goop at Home Depot and the "Pit Crew's Chioce" at my local auto parts store.

Because when NASIOC split off from the unnamed other, a lot of the old pictures were lost/dumped to save disk space. Also, new posts can't include photos anymore for the same reason (but they can include links). It's a bummer, but then again we don't have to pay for NASIOC, so it's not our decision.
