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)?
