Hello,

I have recently changed the stock speakers to Hertz ECX 165.5 and the audio is worse for some reason. The highs are very distorted, even at low-ish volume (28-30 out of 42 if I remember correctly). It distorts so much that it's like someone talks in a bad mic where the "s" hurts. The bass and meds are fine. If I want to make the highs bearable I have to put the equalizer with the highs way down -- unacceptable since the sound is completely changed.

Is it because the stock HU is bad ? someone told me plugging a good dac-amp on the aux input could make the sound better, is this true (and obviously using it instead of bluetooth)? If not, is there anything I can do besides changing the HU? It's pretty expensive and most of them look really bad aside from the expensive touch screen ones.

Thanks

 

sorry, I messed up. this is for a Lancer ES 2011. Can this be moved?

 

If you have an aftermarket HU and amp this info from Rockford is a help

The info in here works for any aftermarket HU and amp not just Rockford

 

This method works very well as well

Did your ES have the optional Fosgate setup or just the base radio?
