I am having problems with this (junk) infinity stereo . The volume **** goes up to 40 and at 20 you could barely hear it, and at 40 not very loud... Is there an adjustment on the stereo or the amp... Does anyone know where the amp is....Does anyone know if there are rca jacks to add an amp... Please help

 

Sounds (no pun intended) like you have a problem with your system.

20 on mine is quite loud. 40 is almost painful. I tend to have mine on about 12.

Can you take it to the dealer to have a look?

 

kyzersosei, You may have a bad amp. Mine works just like english_bob explained.
