.. quick update..
Followed HeavyDuty's instructions, and pulled it off in less than 15 minutes..
the only rough part was matching the color coded wires with my Pioneer AvhP4100 harness, which was easy.. only the power wire's color was different.
Put all the wires together, used the same ground location that my Alpine amp was using, fired it up and Voila.. instant bass!
I spent an hour after work to properly route the wires underneath the carpet, through the sides, then up the center console where the reciever is as shown in the PDF diagram. In all, very happy with the product, and im thinking of getting the bigger 10" driver, 10100 version and giving this one to my wife. Need to beat the sub in first
Thanks for the help, cant believe even i pulled it off by myself *during lunch*, saving the labor of going to an audio shop!
