(((Could you clarify your comment in the above conversation with Mitch4t, where you said, "Some say front firing woofers have greater impact.))
Ok try this
Go to the wall mart nearest your home that has a Car stereo display..
Listen to the pair of 6x9 pioneer speakers and adjust to a nice volume and music you like.
Next you have a choice to push the red button add the Upper positioned Add on woofer or the Lower positioned woofer.
switch between them both
now choose the one that blends together better.
my money if you can hear goes on the one closer to the floor.
Cheers Johnnyr
