Ok I had infinity speakers installed in the front and back, a rockford fosgate 4 channel amp, a rockfordfosgate self powered 10in box, and 3.5in rockford fosgate speakers in the front aswell.. all this conected to the t harness that I.A sells.. now where the t harness is connected there are alot of adapters and splitters there to connect everything.. so it looks messy .. my problem is the sound seems off and not even.. doesn't sound like the left side speakers are as loud as the right side.. the 4 channel is hooked up to the 6.5s and the 6x9s.. anyone have any ideas on how I can clean this up??

Rockford Fosgate Punch P132 3.5-Inch Full Range Coaxial Speakers

Infinity Reference 9632cf 6x9-Inch, 300-Watt High Performance Two-Way...

Thats a brief description of the list I had installed.

 

Check the phasing is correct. Plus to plus and minus to minus on all the speakers. It just needs one speaker to be connected out of phase and the sound shifts.

Which car have you put this in?

 

In the 2009 mini cooper

 

You can use the SpeakerPop app to test the polarity of the speakers (iPhone). I know they have it for Android as well just not sure the name of the app. I installed 2 speakers the other day and I kept feeling something was off. All the stock speakers were giving me "+" with the app. The new ones were giving me "-". I switched the polarity and now the feeling I had is gone
