adding amp and sub to bose system

i want to add a amp and two 12 inch subs to my bose sound system. how do i connect the rca cables and amp turn on wire to the factory deck?

If you do not have an RCA output in the back of your factory head unit then you need to hook up a line level adapter this will take speaker level output and convert it to an acceptable level for your amps RCA inputs. To turn the amp on you need to use the "remote" wire. This is the same wire that would make your power antenna go up when you radio turns on. To verify that you have found the right wire use a voltmeter to make sure that the wire you are using puts out 12 VDC only when the radio is on, otherwise you will probably end up with a dead battery.

you could also do high level input from the amp

94mx-5 explained things pretty well. I would use a line-out converter over the high level inputs. If you ever add a aftermarket headunit, you will already have your rca cables run.

After adding one thing one day, another the next, and another the next, I have found it easier on myself to start planning ahead for potential add on's. That is much more convienient than tearing your car apart, then putting it back together and just repeating the process over and over and over and over........................

thanks to all that helped me on this one-i have used the adapters a long time ago on tape decks.  the thing i am still not sure about is the remote turn on wire to the amp.  the antenna only comes up when the stereo is set to radio, not on cd.  how can i turn on the amp without a manual toggle switch to it?  thanks again..

i believe you could use the ignition wire that goes to your headunit that turns it on when the car is on...you may want to double check on the amprage though..

yeah depending on the car you can use you're ignition wire coming off the radio.....that'll keep the amp on after you switch from AM/FM to CD or DSR....if you can't get the amperage off the radio circuit you can also tap into the ignition harness, although using a fusable link would be highly recommended
