as you approach the rear seat, you have to remove the bottom cushion by pulling straight up on each side. This allows you to continue to run your power wire to the trunk. Once you have the power wire running the way you want it, you can replace all the parts you had removed earlier.

The next step is to find the bose amp underneath the trunk coverings on the driver's side. There are two harnesses that are running to the amp. The one you want is the blue harness. Remove that and identify your input wires:

Head output rear right + blue
head output rear right - pink

head output rear left + teal
head output rear left - purple

remote wire light blue/ silver

you need to be able to convert 18 gauge wires to an rca jack to connect to the amp. One way was to get an rca jack with a twisted pair of wires that you can cut and then splice. Another option is to get the jl line conversion that i used (pricey - $25, but i couldn't wait for mail-order). Splice them with in-line splicers available at radio shack and tape it up with electrical tape. You also want to splice into the remote wire for the amp. Although the jl amps have audio sensing power-on capability, it is unreliable (i found out the hard way) and i recommend using a direct remote power-on line.

Also, when the wires from my factory deck to the Bose amp were spliced they were cut off from the harness (i.e. so it only goes from headunit to subwoofer amp for the remote turn on and the left/right audio signal) and soldered to the new wires going to the aftermarket deck. Is this alright? Or do I need to resolder them back to the wire in the harness (so it goes from Head Unit to subwoofer and Bose amp)?

I was told by the local auto electronic sources that T Taps should bot be used so that is why I had them cut and soldered but now I really regret it .
