There are a couple of ways you could fo about doing this. One of the easiest is to buy a signal converter box from any car audio store, should be ~$10-$20, then you can splice into the connenctions going into your rear speakers. This is a fairly simple and easy way to go about doing it since most amp will be mounted in the trunk you have all the wiring back there. Only the lead and power from the amp need to be run to the front.
After that, there is another place you could mount the signal converter, directly behind the BOSE into anyone of the output speaker wires.
I don't know about the BOSE amp but thre is another type of signal converter which allows two RCA's to be plugged into one output RCA. It is a small plastic box which has three seperate pairs of RCA plugs.
I have only tried the first method which I reffered to, and I liked if not was pleased by the result. I used a Rockford Fosgate signal converter which was excellent since it had seperate gain controls. It was also pleasing to the eye, if your worried about unsightly clumps of wires.
Hope this helps.

Surge Diesal, when you said that you bought a Rockford Fosgate signal converter, are you referring to a line level converter? If you are, does it sit behind the head unit or does it sit outside the dash. I have a RF amp and one JL 12W0 and I'm looking for a line level converter. Does the brand make any difference or are they all the same? How much is the Rockford Fosgate line level converter? Thanks.

Which signal wire is which?

I tried to e-mail Russ, who created the FAQ on adding a sub to the bose (http://web2.airmail.net/scutchen/max...ht.htm#bosesub), but my e-mails got returned. I noticed in there that step 14 only glazes over "two mixed colors" for the + and - signal wires.

So which is which? I remember there being a red with silver spots, and a green with silver spots. Can anybody who's done the tap provide a little more detail? I'm so close to finishing (other than having NO time to wire it up)...

Typically Red is + and green is -, but don't take my word for it. . . If you reverse it it shouldn't hurt the speaker, it will just put the speakers out of phase with eachother therefore canceling the sound altogether. . . Or at least that is what I have been told.

You can either put the signal converter behind the dash, and run the RCA's along the length of the car. Or, you can splice it into the back speakers. As far as the wires to use are concerned, they are the sound output wires. As in any of the wires coming out the deck leading to the speakers. If you want the best temp set-up may I reccomend going down to your audio store, pick out a $15-50 converter, and hooking into the sound wires for the rear 6x9's. I tried this way out just to test out various subs, but I bought an aftermarket deck for a more permanent setup.
MAXIMIZED- The signal wires he is taking about are the ones from the BOSE amp, I think. If you take out the head unit you will notice more than four wires, but there are four running from the amp.

Thanks for the help Surge Diesal. When hooking the sound output wires to the wires going to the rear 6x9's, what is the best way to connect the wires together?
