My Bass no Boom???

[sort_o_sane]

Ok i don't know whats going on but here's my issue and hopefully someone can see the error since i can't.

07 yaris LB w/ Stock HU
I ran wire from the rears to a line out. This then ran to the amp. Everything was fine until i stupidly blew all 4 cabin speakers being a dumbass and showing off.

Replaced the 4 speakers (still the same wires to the line out, in the same configuration it was before) and now i have got to fade all teh way to the rear to get my subs to "Thump" but when i have even balance between front and rear they don't exist. WTF?

Now if our grand "Leaning ECU" comes into this topic as having learned i have bass and wants to kill it, i'm going to burn the car.

If need be i can get pics of everything, but i am not sure that will help. Everything is connected as it should be, amp is fully powered and like i said i get bass, i just have to fade all the way to the rear to get it.
