    Adding Tweeters to 2009 Base WRX

    Hi,

    I am planning on getting the Premium replacement sail panels for my 2009 Base WRX so that I can easily install component speakers. There are two questions which I'm hoping you all can help me with:

    What is the Subaru part number (local parts dept seems confused)?
    What size constraints are there on the tweeter itself (mounting size and/or speaker diameter)?

    FYI: I am considering Diamond Audio, Focal and JL Audio.

    Thanks,
    Evan

    If your going to buy the premium door sails for your base... Why buy other tweeters.. The premium tweeters should be a good compliment to any sound system... Plus it would save you money... Besides if you run JL or other high end brand of tweeter you will have to amp your output.. Yes even your tweeters will need amped.. I dont know if the imprezas come with an oem amp from the head

    Are you using the OEM head unit? If so im not sure if it supports the tweeters... I know the wiring is already there but I dont know if the base head unit sends a signal for those or not... Would be worth looking into... but you say your going component speakers all around so im going to assume you already looked into amps and other head units...

    You could always just go to a dealership and ask to see one of the premiums and get a quick measurement that way... They are a pretty tight squeeze so i dont think you will to much more room to work with aside from whats provided stock

    Hey Poohbear,

    I'm only purchasing the sail panels, not the tweeters.

    The component speakers come with tweeters, but also a cross-over unit which dictates which frequencies go to which speaker. I'll be powering these off of a Kenwood DNX6140, and since the sub is handling the lower frequencies, it should have enough juice to power the component speakers.

    I was able to order the sail panels afterall. They will be arriving in 2-3 days and came out to $16.56 each, which is approximately what I've seen others quote the parts at.

    Sail panels are the triangular piece in the front corner of the driver and passenger windows. On the 2009 Base model, these pieces are just plain plastic, while the Premium has tweeters embedded here.

    I purchased the ones with mesh so that I could install tweeters from component speakers behind them. It's a tight fit, but seems as if it should work.

    You can order them from your local Subaru Parts department. I had to try two before I found one with a competent enough tech though. YMMV.

    Thank you, that's kind of what i figured.

    Do you have part numbers by any chance? I have a base 09wrx hb as well.

    Thanks!

    Sorry, I don't have the part number off hand. Mine will be arriving today/tomorrow though, so when I pick them up I can let you know.

    Sounds good. Hopefully it can accomodate 1" aftermarket tweeter that comes with Polk components..

    Mounting the tweeters in the factory locations will not give the best sound. Having the tweeter and woofer so far from each other creates massive sound seperation (where the sound from the tweeter reaches your ears way before the drivers does). Although it is easier for installation.

    I run a car audio bay and I can put up some pics of where we installed my components in the front. Il try to do it tonight. It gives a very clean look and great sound.

    Doh! I just got a call from the parts department saying that my new sail panels have arrived.

    I was always under the impression that having the tweeters up high in the sail panel was most desirable since it allowed the highs to be directed towards your ears. In home theater, you can adjust the delay on your surround speakers to compensate for their proximity to your listening position; but the distances inside a car seem nearly negligible in comparison.

    Please post the pics when you get a chance, I'd love to see an alternative to hiding the tweeters behind the sail panels.

    the tweeters should be at the ear level for optimal sound.. I guess it depends on the music you listen to.

    As I was driving around last night, I noticed that above the woofer, the door panel is angled upwards. Has anyone placed a tweeter there pointing up?

    Im sorry but that is not correct.

    That is the worst place for optimal sound staging. Any manufacturer you talk to will tell you a tweeter should be within 6-8" of the woofer for optimal sound. The problem is having the driver and tweeter so far apart means all the treble reaches your ears before the bass does.

    This actually confuses your brain as you are trying to prosses 2 different sounds and put them together. I have worked in car audio for many years and the sail panels is in no way a good place for a tweeter. This is why a lot of aftermarket companies make kickpanel mounts for component systems.

    in my 09 WRX we have mounted the tweeter in the small angled part above the driver and it offers great sound staging. There is also lots of room to mount a crossover inside the door panel.

    nice install.

    There are really two schools of thought on tweeter placement. Even if you place them in the stock location you can adjust the crossover to improve the staging. Tweeters can also be reversed to slow them down, so to speak.

    The tweeters look really slick in the door panels! I am currently leaning towards having them installed there. Anyone want to buy replacement sail panels?

    I just hope no one spills a drink in them!
