Audio Systems: re: 2007 Pacifica Subwoofer install, sorry for the confusion, response link

Question
In response to other post ('2007 Pacifica Subwoofer install'): 'allexperts' auto email failed to supply response link.

Sorry for the confusion.
Q1) Even though I do not have the oem sub/amp combo, are there signal wires behind the blank grille that I can tap to supply the signal to an after market powered sub?
Q2) If there is a signal wire behind the blank grille is the signal already crossed over for a sub (i.e. @ 80hz) or is it full range?
Q3) What is the possibility of powering an oem sub with a after market amp (install a salvage sub/enclosure but use my own amp)?
Q4) What was the size of the oem sub? If I were to install the oem enclosure could I use a third party sub for upgrade?

Does this clear things up? Thanks.


Answer
A1) No, those wires are dead without the upgraded amp/brain
A2) See A1
A3) Anything is possible
A4) About an 8 inch single voice coil. There is no room for anything larger.

Have you upgraded ALL the other speakers yet? If not, you really should. They suck.
