I wanted to post some pix of the speakers I installed in the front doors
of my new 2010 Forester. I saw some earlier posts that the Polk db651
speakers will fit, but Crutchfield recommends the shallow version (db651s).
There is no need to use the shallower format, and a small benefit to buying
the standard version. For one, the db651 speakers include adapter brackets,
which are critical to mount the speakers properly. Although Crutchfield will
provide separate mounting brackets, there are less expensive places to buy
the speakers. There is no need for an aftermarket mount, given that the
Polk adapter does (mostly) line up fine in the latest Forester doors. Given
that Polk does not provide these adapters with the shallow db651s, and
they provide slightly less bass response, it makes sense to use the standard
version.

I did need a few extra "parts" to complete the installation. There were no
wires in the Polk box, so I used some stranded wire I already had. I picked
up a few female, spade connectors to attach to the Polk terminals. In
addition, I got some 1/4" foam weather stripping at the hardware store to
cushion the mount bracket, and keep from adding any new rattles. The
foam also helps when the wires route from behind the speaker, so they don't
have to pull past the interior of the door which houses the moving window.
As an added note, the speaker does not interfere with the window travel at
all, even without the mounting bracket. There is plenty of room for these
speakers behind and in front of the door's surface.

I did have to drill one of the mounting bracket tabs to align with the door's
existing plastic screw holes. I decided that was preferable to drilling the
door metal.

I know this has been covered before, but if there are any questions
regarding the steps, please feel free to ask. Overall, the Polks provide
a nice upgrade over the standard speakers, and a great addition to my
(also) new Pioneer in-dash DVD unit.

Photos to follow: note that these were taken prior to insulating the wires.

DVD parking brake bypass

One other modification that I made during the speaker install was a bypass
for the parking brake signal wire required by the in-dash DVD player.
I don't really plan to watch anything while driving, although the kids may
differ in opinion. In any case, I found the need to use the parking brake
a cumbersome requirement by the manufacturer. Since the DVD looks
for a ground signal to toggle off then on, after the car has been powered on,
it made more sense to use a momentary switch in-line that is normally
closed (connected). By wiring the switch in the path to ground, I can simply
press it to break the line, and when I release it will remain grounded,
simulating the brake switch itself.

This solution proved to work very well, and I prefer it to the alternate bypass,
using a 12v relay slaved to the stereo auxiliary power. Although the relay has
the benefit of needing no user intervention, I didn't like the idea that it would
constantly draw power whenever the radio was on. I like the simple switch,
and it gives me an excuse to find a location for installing one. I settled on
the existing AUX jack within the center console. It's out of the way, and
close to easy grounding locations near the actual parking brake assembly.

Opening the AUX jack box revealed enough room for a small button, and
there was enough room to pass the wires out the bottom below the console.
A bit of drilling opened up enough space to screw in the button, and it sits
nicely with the existing jack. I'm pretty happy with how it looks, and now
I get to have a secret button in my car. Who doesn't love that?

How do they sound?
Did that mod to your parking brake also allow you to use/input destinations on your nav?
Sound is excellent, even with the factory rear channel. The Polks really provide the missing bass and clarity that the factory speakers lack. Eventually, I'll put a matching set in the rear doors.

I don't have the Nav add-on, so I don't know if it would have the same effect. If it uses the same method of detection, my switch is indistinguishable from having the brake set. However, a nav has access to your current speed, so it could lock you out whenever you're moving over a certain speed.

SWEET! I live right down the road from Crutchfield and stopped in this afternoon to nose around. SO, I'm foolishly looking at Kenwood head unit and JL for powered sub, amp speakers, etc............ What the heck am I thinking cause I'm old enough to be a GRANDPA! LOL

Nice work! I really like the button idea, where did you get the button and how did you connect it? Did you just connect the brake wire from the radio to one end of the button and the other end to the ground?

It is wired just as you described. I got the button at a local electronics shop. You can use any momentary, normally-closed (n/c) SPST button. You could also use a toggle switch, but then you'd flick it off and back to on to fake the brake.

Thank you so much for this post! I am contemplating installing an indash DVD, and like you, have no intention of watching it while moving myself, but wanted it to be able to operate that way to silence my 7 year old's complaints about the Forester not having a DVD for long trips like our (replaced) Odyssey had. While not really researching it to any great lengths, I did suspect that the in-dash DVD players had a safety circuit of sorts to prevent them from being used while the vehicle was in motion. Your post "solved that mystery" for me! Now the remaining question is, what head unit do I want most ....

wow nice writeup and nice custom job on the brake switch.

Einy just for your info and for others some companies make switches to bypass the brake requirements on in-dash dvd players. I have an alpine DVD player and pac-audio makes a piece specifically for alpine's so you don't need to use the brake, of course with alpine it was something stupid like push brake, set parking brake, release parking brake and set parking brake again before you could watch a dvd.

I heard the easist way to bypass on any DVD HU is to connect the brake wire to the ground. You wouldn't have the option of turning off the DVD player while driving but it would bypass the connection to the brake wire on the car. Connecting to the ground is so much easier.

You can't just ground it

I heard the easist way to bypass on any DVD HU is to connect the brake wire to the ground. You wouldn't have the option of turning off the DVD player while driving but it would bypass the connection to the brake wire on the car. Connecting to the ground is so much easier.
This generation DVD HU won't work if the signal is constantly grounded.
It requires the signal to toggle, which is why I used a button.
Other people have wired in a 12v relay switch connected to the remote turn-on.
That just seemed like overkill, given I will rarely use the DVD mode, and
I didn't want to install something that could wear out from being used so much.

These days, the manufacturers are serious about keeping the movies out of
the driver's view. I am already planning the connection of an old screen
we have to mount in the back seat for the kids to watch.

But, the next project will be the reverse camera wired to the DVD screen.

I didn't realize that, I guess regulations caught on and tried to fix the dvd playing while driving. I'll just use your idea and connect the switch
:icon_biggrin: and end up getting the same Pioneer head unit or something similar. I installed Dual DVD Head rests, but I'm not sure if I'd connect them to the head unit since each have their own dvd players and can play off each other.

I just installed the DB651 in my front speakers and they sound great! Already ordered another pair for the rear speakers. Its amazing how cheap the OEM speakers are...

Great writeup and appreciate the info!

My 651's arrived today .... can't wait to get them installed, thus starting the inevitable "total sound system upgrade" that will follow!

I started poking around with this speaker install last night and ran into a small issue. My X-Premium came from the factory with the tweeter option, and when trying to "pull off" the tweeter housings, noted that the molded in post that secures the housing to the door panel "stretches", but won't disengage from the hole in the door panel that it is plugged in to. Evidence of this is the fact that the tweeter housing is still "engaged" in this hole, but now is loose relative to the rest of the door. Worst case - looks like I'll have to possibly buy a new pair of tweeter housings (~ $12 / each) if they get destroyed during the removal process, but wanted to see if anyone else has a better way to remove these? If so, I may be able to get away with just replacing the one housing that I already stretched the post on .... thoughts ??

einy, not sure if you stretched the post or just distorted the metal spring clip on the very end of it. Did you actually pop the entire housing off the door? If you did was the metal clip on the end of the housing post? Mine stayed in the door slot.

When I removed a housing for the first time I didn't know there was a spring clip on the end of the post that held the tweeter housing firmly to the door, and after pulling it off and realizing the spring clip stayed in the door had me using needle nosed pliers to pull the now distorted clip out. Had a heck of time reshaping it so it held the housing properly again.

That was something I don't remember anybody mentioning before when working with the tweeter housings.

Einy,
You almost certainly have not stretched the plastic, but rather have pulled the plastic post off of the metal clip in the door. Make sure the plastic tabs on the window-side are clear of the metal, and pull the sail panel straight off. You may have to re-seat the spring clip when you've done, but unless you break the tabs it will go back on fine.
