Rear speakers sound horrible after installing a D3.

^ Just be careful of that control module underneath the stereo on the hump in the dash. That's the airbag control, if memory serves. You don't want to set those bad boys off.

Well I got mine sounding better, it was all in the sound fields and EQ.

I think I will get a Y-splitter though because if you are right we are not getting bass from both left and right sides.

I am going to research that some more before I do it but i think you might be right.

Ok CatchMeIfYouCan631 is right, some information I found on this issue on the mustang forums:

 

* Shaker/Skipper 500 is a 6 speaker setup (4 speakers + 2 front subs);

* each front sub is powered by it's own amp;

* Shaker 500 has only ONE set of sub outputs (i.e. two mono subs running off one set of inputs);

 

-->This<-- PDF shows the Shaker 500 connection diagram.

Pins 1 & 2 on connector J4 is the mono output of the bass on the Shaker 500, for the Shaker 1000 the rear subs would be 5 & 6 though not show here.

 

If you look at THIS schematic you can see how the the front sub amps are tied toghter.

 

So there are two options here.

1. Get a Y-cable that is two male to a single female and tie in the white RCA connector from the Merta harness and tape off the red one.

2. Find the amps and run seperate feeds for the left & right to get stereo bass and only use the Metra harness to turn on the amps.

 

From what i am reading the amps are behind the drivers side kick panel.
