so I've looked at all kinds of info and just to add a amp the best answer i found is to wire up the LOC to the factory sub under the seat. This is an 08 with nave and Bose system. I have all my other wires ran but want to get the wiring straight.

There are two red and two green wires going to the stock sub. there are a lot of other wires going into the stock amp under the seat. The PAC piece has a 12v power wire and all the speaker wire connections and a ground. I assume I can find 12v power from the wires going into the stock amp. My main question is what wires do I need to splice into under the seat to go to the PAC? This is an OEM4 but it seems like I just run the wires to the rear left and right possibly? Looking for any insight I can get

You need to find the remote wire. Wish I can help more but I paid a guy $50 to install mine lol lol lol

the remote wire is actually an easy one for me, my main concern is where to tap into the speaker wires and which ones to tap into.

do you know if they installed it under your seat at the subwoofer or behind the radio or somewhere else?
