I want to keep my stock head unit.

So I decided on installing new DB651's in the front and rear doors as they should work pretty good and barely fit. And I want to add a sub in the back to run off the stock head unit too. I have speaker level outputs only.

Can I run my speaker wires in parallel ( run the speakers and connect the same circuit to the amp) with high level inputs into the amp for a sub and not lose the stock head unit power to the speakers?

Or will connecting speaker level inputs from the existing speaker wire to the amp "suck the power" out of the speaker leads and kill or reduce the DB651 sound?

Should I be looking at an amp with high pass filters?

    2003 Subaru Outback= can fit replacement DB651s in frt + rear doors, want to add some bass in the back side panel. The stock "premium" subaru headunit should push the DB651s ok, and it has AM/FM/6CD changer and Weatherband- I want to keep the weatherband.

    To answer your original question, no it won't effect how much power your speakers receive.

    However, the advice given by DSkip is right on and would sound better than what you intend to do.

    You dig up a 3 year old thread to start spamming in? What an ****. BTW, REPORTED.
    If you can't hear a difference, don't waste your money.
