Well I was out in my garage just hooked up my ipod to my new headunit and was playing around with it when all of a sudden my mid/highs get real quiet and my bass got real loud, I have pioneer rev 6.5 components running on a crunch100.4 amp set in 2 channel mode and my subs are two 10 pioneer premier championship series dual 2 on a audiobahn amp.( forgot model) And the headunit is a sony xav-7w flip out.
I tried to see what it was so I turned the subs off and faded the volume around and it plays fine out of the passenger side speaker but is real quiet on the drivers side. I tried fading it all the way to the drivers side but it still is quiet but it also still plays the same out of the passenger side. What should I do to trouble shoot this?

 

sounds like you some how knocked the eq on the ipod on to the mega bass or whatever that setting is called

 

disconct ipod and then try it... sometimes when a song is recorded it is setup to play out of certian spearks like front left front right for example... also some are recorded where there is still music but the bass drownds it out ... disconect the ipod try it like that and if anything disconect the rcas that run to your sub amp and conect them to your highs and mids amp... sonys are notorius for there rca outputs to go out... pm me with any questions and ill see if i can help anymore...

 

went back out to my car and popped in gone in 60 secounds seems to be working fine now. Just my stupid ipod acting wierd. But the bass is still louder then normal.

 

you could have setting on the flip out that switches from cd/fm/and dvd mode it adjustes to the tones of the stuff playing...

 

It might never thought of that lol.
