Did you find this out?
Are you replacing the AMP also or just the sub?

 

I have the Alpine SWR-843D Type R which is 4.5" deep. I used a 3/4" MDF Spacer and it still wasnt enough. I was able to cut out a small portion of the plastic waffling inside of the enclosure to get it to fit.

I would guess its about 3.5 " deep.

Keep in mind if you use a spacer, the sub will have to stick out of the rear trim panel since the subwoofer cover will no longer fit over it.

Only upgrade the sub if youre planning on doing the amp too. Otherwise its a waste of time and money.

Also, my system is an 07 ELS sytem....it may differ than yours.

 

Can you take a picture of your engine firewall where did you run power cable?

 

I will take it apart this weekend. Will check how deep is for sure. I was looking all over the place for answer and it varies 3-5 inches. I will not use any spacers, want to keep stock look.
If my bad boy will not fit, will go to best buy and buy shallow mount pioneer subwoofer.

 

from what I looked online its a Panasonic subwoofer no dimensions though.
Let me know if you upgrade the amp to, I am interested

 

i will install Alpine MRP-M500 Monoblock amp. It is small and powerful enough.

 

I replaced mine with a pioneer shallow mount 8 inch sub. The factory sub is basically the same as the shallow mount just not the same quality of course since it is factory. I tapped into the factory wiring inside the sub box to get a signal for my amp which is mounted in the rear storage compartment.

 

How does it sound? Noticeable difference?

 

Is the wiring off of the deck Speaker Level connections or LFE?

Any pictures or amp placement and what the speaker looks like? What type amp are you using for the Pioneer?

 

anyone want to tell me how they run power cable from battery to amp through firewall?

 

There is a large rubber grommet to the left of the brake pedal with some factory wires passing through I just pushed my power wire through there after cutting a small slit. Then just ran the wire under the side trim to the rear storage compartment.

 

Done

All done, sound good. Thanks for the help.

Is that the original box that your subwoofer is in or is that a customer fiberglass box?

Did you use any spacer? I'm looking at either a rockford or Pioneer shallowmounted subwoofer

 

Did you have to remove the re-inforcement walls in order to get it to fit?

I don't really want to have to take off the whole side panel and cover it with fiberglass.

 

in order to change subwoofer you will need to take side panel. There is no way to remove just subwoofer grill.

 

Also got any pic with the cover all back on.

 

How difficult was it to remove the side panel to expose the subwoofer (this vehicle has its panels better made and secured than other vehicle brands, and therefore I am unable to determine exactly where I need to pull/pry on the side panel)? I thank you in advance for your assistance!

 

anyone upgraded door speakers and tweeters? findings on improvement? depending on complexity of the upgrade, I may throw in some Boston Pros.

 

It will sound much worse. You need to change amp with the speakers.
i did try to change just speakers with 2ohm infinity kappas. No improvement just made it sound more silent.

 

did you run the included crossovers witht the Kappas?

 

no and yes, no difference in sound.

 

Can anyone tell me the colour codes for these wires, its for the stock subwoofer?

Other 2 pics is just for those who are curious what the sub and stock amp looks like.

white in the middle... i think remote, not sure, dont remember.
Blue +
Pink -

 

^^^ why would you want to turn your amp with radio???
You are good right now.
wired my remote wire from fuse box...

 

My guess is that most aftermarket stereo's shut off the amp remote wire when they stereo is turned off. I also do not see any real reason for this. Maybe we can be enlightened?

 

Ok thanks.

When I had an 04 MDX, I had BestBuy do the Amp install.
They went from behind the factory deck for the install, and they ran a remote wire from the front....end result, the Amp will shut off when the factory stereo shut off.

Why I would prefer this again?

Ideally on battery drainage when I am not using the stereo while parked, chillin, might be charging a device, etc...
Also, most times I do find myself driving without the stereo on. Now the Amp is on for no reason. Most likely the cover is down, and the Amp is getting hotter.

And I am thinking to add a second Amp, which could be more drainage, more heat, and on for no reason when not in use.

Pic shows where amp will be, and the cigarette lighter power source used as remote.

 

Hey poser did you get the sub enclosure at a audio shop? Online? . I want the same thing.

 

As you can see, zapco has a remote wire going to the front.

I found this post, speculating the colour codes for the wires.
I might be thinking of going behind the deck in search of a remote connect, and doing it myself.

Or if I get lucky, maybe the XM satellite module in the rear, I can use the power supply as a remote....I think it turns on with the deck, because a few times the channels seems to be loading.

 

Eckoluu, What are the colors on yours? I have a 2012 base model also. I'll be opening up that side panel to remove the sub inclosure in a few weeks. If I know what color it has, i'll try to find out which is which.
Thanks

 

Thank you so much
Wire color Red/Blue/Gray/Black , Sorry there should be one more wire when i took the panel out took pictures the plug. Only show 4 wire can't see the last wire sorry. Hope you can help out plz. One question i have hi/low converter can i tap in to the plug?

 

I got this from a very kind installer.
Can someone help me decipher this:

"Subwoofer (+/-)--The speaker wires are blue - grey (1); red - black (2) at the amplifier behind glove box, gray 18 pin plug, pins 12 - 3; 17 - 8 (base model). or blue - pink at the amplifier, gray 18 pin plug, pins 10 - 1 (except base model)"

What I get is this, and please anyone correct me if i'm wrong.
blue and grey are +
red and black are -

I would use blue and grey or red and black as the + and -

I think the reason for the 2 pairs of wires, is because the sub is a dual voice coil and the amp is feeding each coils separately.

Once I opened up mine, if all the wires are the same as yours, i would use the red and black, connect that to the high level of an amp and see how it sound. This is what I would.
Notice, i'm saying what I would do. I only saying this because i'm not 100% sure. But for me, experimenting with this option cannot seem to hurt.
I'm in the process of building some speaker pods so i'm not sure when i'll get to opening up the sub compartment, but i hope it's soon.

 

I ran my zero gauge power wire from the battery to the back today, and a remote wire just in case. Small progress. I'll try to wire up my amps and processor next weekend.
