    Question Can Polk Audio tweeters use stock crossover (if there is even one)

    I am new to installing car audio, but I am handy in general with electronics, repair and definitely car stuff.

    With that in mind, I am about to undertake the replacement of the stock 2015 WRX front speakers and tweeters with Polk Audio component set.

    I would get metra adapter, speaker adapter from subaru audio guy, and these speakers.

    My question is:

    Do I need to install Polk's cross over for tweeters, or could I reuse the existing wiring from stock tweeters (do they even have a crossover)?


    Please advise.

    you will need the new crossover... for starters I believe the crossover is ON the speaker. Secondly the stock tweeter is a 3" and therefore probably has a much lower frequency response than you would want on any aftermarket tweeters

    Do you have the stock stereo option? If so look into upgrading your HU first rather then new speakers. I went the rout of new speakers first and could have saved some time and money with just an HU upgrade.

    You may also want to contact http://ae64.com/ and speak to them. If you are going to stick with a stock stereo you may want to consider a break out harness so you can keep the original cables intact

    +1. A head unit upgrade and stock speakers provides enough audio quality improvement for most people. The WRX gets a lot of road noise, so if you really wanted to deck out your audio system, there's tons of modification required (sound deadening/dampening, amps, all new speaker wire, and some other things).

    Just a heads up, I don't know if you have those speakers already, but I believe the grill on the tweeters is not removable.

    I have the mobile monitor series and the tweeters have a similar grill and it is not removable. I don't know if that will make installation on a 2015 more difficult. It has made placement on my 2014 extremely difficult.

    The stock wiring uses a capacitor in parallel with the door speaker wiring to serve as a high-pass filter for the tweeter. You'd want to install a real crossover.


    Replacing the head unit would be a much better bang for your buck though. The stock component speakers aren't too terrible with a proper head unit powering them.
