Stereo & Electronics - aftermarket HU. using stock monsoon system (problems)

ok i got a alpine HU, i am friends with a guy that works at the local car audio store and i have done alot of car audio in the past, and he told me what to do with this monsoon stuff.. well the problem is...i got the wiring harness and installed it like anyother cd player.. and it works great BUT....only the front speakers and the hatch speakers are working and the bass is no where as loud as it was..when i was doin the install i noticed there where 2 plugs on the back of the factory HU. one with the mess of wires like normal. and the other with like 5 or 6 wires..i called my friend and he told me to hook the remote wire out the the aftermarket HU to the blue wire on the wiring harness that, thats what tells the subs to come on..well the to backseat speakers are still not working.. and he couldnt figure out what that one harness it for..my guess is either the sub speaker wires or the factory cd changer controlls.....if it involves me spending more money to get them to work right then fugg it i just wana know what to do to get it sounded like it was and to get all the speakers to work..sorry for the novel! please help! :bang:

The other plug is for the CD changer. You should probably just get the right wiring harness and you will have no problems. It worked for me and just about everybody else, and it's only like $15.

yeah i just went out there and fucked with it and got it working right thanx sorry for the long post for me to fix it alone lol...
