Ok so i decided against putting my aftermarket HU in and im going to stick with the stock HU and just add my subs to it, from doing some research i gathered that it IS possible to just splice into the rear speakers with a line converter and hook that to my amp. I also learned that i need to splice before the bose amp, but i have no clue on which of the numerous wires going into the amp i need...can someone help me out here with specific colors, or if someone has a diagram that might be easier..

This is according to AllData.

Left Front (+) = tan
Left Front (-) = dk grn
Left Rear (+) = brn/wht
Left Rear (-) = brn
Right Rear (+) = dk blu
Right Rear (-) = blk
Right Front (+) = lt grn/blk
Right Front (-) = lt grn

These are colors of the wire harness between the head unit and the Bose amp (so they are the input to the amp). They are basically line level signals already and should not need a converter.

Awesome! thanks for the breakdown for the wires, as for the line level converter, i know that they are line level already, but i need to convert them to RCA so i can hook them to my amp...it doesnt have a line level input on it..

But it wouldn't hurt running one IMO that way you can turn down the gains a little bit and save your amp.

If your amp has RCA inputs, they are probably line level inputs. If you use a line level converter, it will attenuate the signals even further so they would be unusable. All you need is RCA connectors spliced into the line level inputs to the Bose amp. Those connections are shielded so it is a little more work to splice into. If you are not handy with a soldering iron, you may want to get help from someone who is.

It is possible that some line level converters can be set up to pass the signals through without attenuation, but I am unfamiliar with the features of those products.

This doesn't make sense to me. If you are concerned about your amp, you shouldn't turn it up so loud. Plus, turning down the gain will degrade the signal to noise ratio, which will be minor compared to what you'd be doing by adding a converter that is not needed. If you have a decent amp, there is nothing to worry about unless you have the wrong impedance speakers.

alright im bringing back topic back up again, i am going about hooking my subs up and was wondering if you could tell me if/where there is a remote turn on for the factory amp that i could splice into, and if not, whats the easiest route to go to find a switched 12 V+
