2003 silverado / need help adding amp

    Hopefully somone can help me out or tell me something.

   2003 Chevy silverado Z71 4x4  |  Factory delco 3-disc player |  6 factory bose speakers |  volume on the steering wheel |

   I'm trying to add an xplode 500watt amp to two poineer 10's. | and that's it. Taking nothing out. only adding.

I ran wires from the rear speakers into the high/low input wires that's on the xplode amp.  I then connected the speakers to the amp.  It works ok , but it was like the amp is turned all the way down. The bose are louder than the tens.  The tens were barely even vibrating. 

 I then rigged up some RCA jacks for the amp by connecting the ends of the RCA's to the rear speaker wires. "yeah I know"  but Then the amp gets full power and actually sounds loud like it should, The problem is when you turn it up.. it kicks the amp off as if the ohms are off . The xplode amp has the protection thing on it and it kicks it off.  I think it's just the crappy xplode amp myself.  I tried it bridged, parallel, series, and everything I could think of, and it still shuts off.   the bose never shut off though.  

 I was guessing that the factory amp was sending to many watts through my rigged up rca jacks causing the amp protection to kick the xplode amp off. SO I was going to run the rigged up rca jack from directly from the back of the radio. But I can't figure out what wires are the speakers.  and since it has a factory amp, it seems that the radio don't push no watts by itself, cause I connected a small speaker to every single wire on the back of it and got no sound at all.  nothing.

HOW does these bose systems work?  are they not connected up like regular speakers ?

SO what color wires are the speakers on the plug on the back of the radio. and where is the factory amp located?  Also, the color of the wires on the back of the radio are not the same color as the ones that are on the speakers.

 I've never had this much trouble hooking up one measly amp with two speakers.  I could hook an amp to a walkman before I can get this amp to work with these bose.  I'm gonna try it with another amp tomorrow also. huhhuh "that is"... an amp that don't have no stupid protection crap on it like the xplode amp.

You need to getthe proper adapter to do what your trying to do.

PAC makes a good peice, I think its called OEM-1. Its designed for adding an aftermaket amp to a factory Bose system.   Soundgate makes one too.    If you get the rite addapter, your problem will be solved

  Will this one work:   Ford/Jbl and GM / Bose  Speaker Level Converter.  This 4-channel converter lets you connect after-market amplifiers to a factory car receiver that doesn't have preamp outputs (RCA-type connectors).

 I figured it needed something like that.    

But I still don't get why the amp will work with the high/low inputs wires on the amp, but yet it's seems turned all the way down that way.   Thanks for the reply.  I might try that walmart one if my buddy hasn't carried all the stuff back already.  The one at walmart looks like it would work.
