    Contrary to what you signature says. Read the manual and find out which of the wires from the HU are powering the speakers.
    Switch the fronts and rears. (Front left plus into rear left plus, front left minus into rear left minus should be 8 wires total to switch)

    Not trying to be mean there, sorry if it came out that way. There are good reasons to read manuals lol. Also do a google search on the wire harness you are using to figure out the colors. You can always buy a new wireharness from Advance auto or autozone in you cannot find the color charts.
    am I the only one who has an owners manual or two somewhere in the stack of bathroom reading material?

    I edited the image to show where the only main set of wires on the back of the head unit are connected. Besides the subwoofer out, up there
    on top of the HU (in that photo) there are no "Front left plus into rear left plus, front left minus into rear left minus" connected at all.

    There are two wire harnesses that connect the outputs from that circled area to your car. One connects into the deck and is connected to an aftermarket wire harness which has a connection that is compatible to your vehicle.

    Step 1
    Go into your car and carefully disconnect the two wireharnesses from the cars stock wiring. It should be a white or black connection. Don't cut any wires at this point, simply disconnect the harness from the cars wiring and you may have to press down on the connector to be able to remove it. Bring it to a place where you can see the color of all the wires easily.

    Step 2
    Read the manual and determine which wires go where and switch the fronts and rears (speaker outputs) between the two wire harnesses by cutting them. Strip some of the wire on each end and connect them with wire connectors (avaliable at autozone, advanced auto) or at a bare minimum electrical tape. Leave all the other wires intact.

    Step 3
    Reconnect the deck and wireharnesses to the car and observe. Do all of this with the battery disconnected until you are testing the deck.

    If you are not comfortable doing this take it to a car place and replace the deck. I doubt you will be able to find a car audio place that will charge you a reasonable amount of money to trouble shoot this.

    Re: Rear Speakers not as loud as fronts?

    @West thanks. Like I said more than anything the rear speakers sound, muffled as if they are not getting enough power. Since nothing has changed with the wiring, this sounds like an issue with the head unit. It could be the wiring or it could be from having the wires cramped together in the harness with the head unit that are the cause for the ''loss of power'' to the rears. I'm going to get it taken care of tomorrow. The people at one of the shops I go to know me, they won't charge anything to diagnose the problem. To fix the problem, sure. If Im lucky I will be able to get away without buying a new head unit.

    "Hot as a mf", as you explained, is NOT usual. Yes they get warm, but not so hot you can't touch them.

    I suggest that you disconnect the rear speakers at the HU and see if the HU runs cooler. If you have a short in the rear speaker wires somewhere it would explain why they sound crappy. I also suggest swapping the front and rear speakers at the HU... if the fronts get crappy then the HU has issues.

    But wouldn't the Big 3 upgrade put extra pressure on the head unit to perform?(0 gauge for christsakes)
    No.

    Re: Rear Speakers not as loud as fronts?


    Well.

    I did not end up taking the system to my dealer yesterday to diagnose any problems. The reason is, after I (1) removed the 16 pin clip from the back of the head unit, (2) cleaned the connectors (3) checked the fuse (4) put the wires back carefully in the harness so as not to have the HU mash them= the problem seems to have disappeared. I think the way the person who put my HU in my previous install was not, careful enough to make sure the wires were secured from resting against the HU. I noticed the connect one of the sub outs rca's appeared marred. It had to have come from heat dissipated from the back of the HU. New upgraded wiring should keep this problem from occurring again. Actually I plan on doing the entire car soon. Thanks for the suggestions brother(s).
