replacing rear monsoon speakers help??

[tjclt250r]

my 98 t/a has monsoon,i took of the sail panel grilles,and no speakers in there,so i ordered some kenwoods from ebay......my harness was already modified for 2 wire hook up,i put the speakers in and barely anything comes out....i know that they are crossed over from the factory.....so i guess my question is what wires do i need to splice to make this work? i just want to put the kenwoods in with the 2 wire hook up and have them put out bass as intended......please help?

you talkin about the ones in the back seats? those are dual 4ohm wired to 2 ohm. you probably have the wrong speakers. check the audio/electronics section on here for more info.
