Bose System in 2003 Yukon

I want to hook up my own Amp in My 2003 Yukon to the Bose speakers.  The speakers are a combination of 2 & 4 Ohms.  I need to know where I can splice in to the exsisting speaker wire and run that to my Amp.  I tried cutting the speaker wire before it went in to the Bose Amp but got no sound.  What can I do.  HELPMr Hexed

You need to find a wire that lies between the factory amp and a speaker, your safest bet is to go right to a speaker if you have limited knowledge and tools at your disposal. Ohm rating will not matter here. Find yourself the speaker wires that lead to one of the larger speakers in the vehicle, splice into the wires there. Do not wire into the smaller speakers as they generally have a high pass crossover and do not allow the range of frequencies to pass through that you will require, that is if you are wiring in a sub.Top Secret, I can tell you but then my wife will kill me.

Just a note that adding a higher powered aftermarket amp will make those speakers sound worse(those speakers arnt that much better then the ones that come standard with the truck). Your speakers are going to distort easily if you add an external amp of any kind. I would reccomend upgrading your speakers in the very near future if you havn't thought about it already.
