sub integration on '07 yukon

I've got a Hifonics Brutus and DD 1508 that I have all set up for my '07 Yukon.  The truck has the factory Bose stereo and I'd like to add a little lows.  What do I need to get the signal to the amp?  What about the amplifier turn on wire?

Thanks in advance,

Chris

Does it have a factory subwoofer installed in the cargo area?  If so, the wires you need to tap into are located in the center console.  I do not know how to get to them,, but there is a green pair and a blue pair of twisted wires at the factory amp. 

Maybe some of our hands on guys can help you with accessing those wires.

No on the factory subwoofer.  I may try to tap into the cargo area highs and use a high to low converter.  I just don't know how to tie in the remote turn on for the amp.  I guess I could just use a switch for when I need more lows.

The factory amp turns on with data, so there is no remote wire in the truck. Your best bet would be to use the accessory wire at the ignition switch to turn on your new amp....

Thanks.  I bought a hi to low converter.  It's supposed to have the capability to turn on the amp.  We'll see.

Figured my sub integration out last month. The factory sub in in the center console, as is the factory Bose amp. If you pull out the cup holders the harness is very accessable. I tied into the factory sub wires with the PAC converter. The PAC high to low converter is wire to 12VDC continuous and has a amp turn on feature that works great. The sub sounds amazing. I wasn't sure how it would sound using a high to low converter. I'm very pleased on how well it all turned out. Here's a few pictures.
