So you really think his JVC unit is better connected to all 6 speakers then just powering the front and rear door ones and letting the Bose amp run the ones its built for?

 

this is what you will want to do exactly. Heck try it both ways if you want but that little 10 year old amp is garbage and by doing it this way there is no need to run new wires from the deck-use stock.

 

I appriciate everyone trying to help out here. When I get home from work I am going to take a few more pics of what I have done and what exactly I have in the trunk so I can maybe help clear things up. I have installed a bunch of car audio / video stuff in the past but it has all been done on domestics and this is my first experience trying to install a non-domestic. I think something was missing from my kit is the reason I just ran wires back to the stock speakers themselves. I plan on changing everything out before too long with aftermarket speakers, high level amp and probablly a sub or two. For now though I just want music to play through the rear speakers as they are. Of course I don't want to blow the HU (even if it was a $60 JVC..lol). Thanks for the help.
