    Upgrading 2005 WRX sound system question

    Stock is not doing it for me (at all), I'm going to replace all of the speakers, the headunit, and put subs in the back.

    How much power can I have before I need an alternator upgrade?

    Has anyone had any experience with the Pioneer AppRadio 2?

    What speakers would you recommend for the doors?

    What sub-woofers would you recommend, and an amp to match it?

    Speakers are always a personal choice. I like alpine type r door speakers and focal. I like the pioneer app radio 2. I like alpine type r subs. The amp should always be measured to the sub you use and never more. If you have a alpine type r 10" a good class D 400watt rms would be plenty.
