Adding amps

[Black03]

I had a hard time finding the info I needed through the search feature.

This is for the THX/NAV head unit. I plan on pulling the stock amps and speakers/subs.

I am getting ready to add an AC digital Xover and 3 amps in the trunk. I just need some suggestions as to how to go about hooking up the RCA's to the Xover, and how to run the remote for all 4 units. I'm a little worried about trying to tap into one of the rear speakers because I need all frequencies going to the Xover, not just the mids that were going to one of the rear doors or whatever.

Is there some sort of a pigtail that splits off into RCA's that I can put on the back of the HU?

And for the remote, I'm not sure if I can split it 4 ways and still have it work properly. What do you suggest for that?

dont split it. use a relay. you will eventually burn out your deck if you split it.

I also have an 03 with THX/NAV. A remote wire that turns on/off with the head unit is a little tricky to find. It is located on the driver’s side in the trunk. It is a yellow wire that is in a connector with about 20 other wires behind the carpet near the rear on the side. If I get a chance I'll take a pic tomorrow if you need it. Also I believe there is a factory amp there that you could tie into for you Xover (not sure about that one) Since the door speakers play both highs and mids, I would use them for that portion of the Xover and use the factory sub wires for the low part of the Xover. I like scotch locks to connect to the factory wiring because they are cheap and you can undo your wiring job without cutting the factory wiring. You can scotch lock speaker wire into your factory wiring and then run that into line converter (speaker levels to RCA, I'm not sure they are called line converters). Then the RCAs to your amps. I would use a relay for the remotes also. I saw that crutchfield sold pigtails to run speaker wire from the factory wiring, but why pay shipping and go through that hassle when you can buy a pack of 20 scotch locks from Wal-Mart for like $2.00?
