    Low level RCA outputs or.......? tuning help

    Alright guys, my old Sony deck decided to short out one of the rca outputs.
    So I hit up bestbuy and got me a new deck. Pioneer Deh-x5600hd. For some reason, both of theses rca outputs (one set) are quieter than one rca out from the sony.

    I got it to about the same level, but I have maxed out the settings on the headunit sub out gain and the gain on the amp. The volt out is supposed to be the same. And no, the sub out or rca out is not turned off.

    Does anyone know how to fix this?



    Head Unit: Pioneer Deh 5600hd
    Fronts/ Rears: Stock ATM
    Sub: SQ Hdc3 d2 15
    Amp: Powerbass Asa 1500.1dx
    I think it looks pretty

    What's your volume at



    "When I listen to a stereo loudspeaker playback in my room and an auditory scene has formed in my mind, how would I know that what I hear is an accurate replica of an auditory scene that could be had at the recording venue? Or more generally, that this is an auditory scene that could have existed at all?"

    My volume is set to 50/60.
    My sub output on the headunit is 6/6 and the gain on my amp is all the way up.
    I checked my rca cables and they are fine.
    I'm thinking the pioneer deck just has very low rca outputs?

    Why 50?
    You setting gains with dmm?

    You've probably damaged the preamp section of your amplifier. Disconnect the channel that was bad on the old head unit and see if the amp has more output. But before you do that, turn the gain back down to where it was. ;-)

    Re: Low level RCA outputs or.......? tuning help

    I use 50/60 because that is about the level before the headunit clips at a noticeable level. Everything above that starts distorts then clips and sounds bad.
    I dont usually set my gains with a dmm because I dont really find it to be accurate. And I dont have an oscilloscope.
    I have tested both sides of the rca sets on the headunit and the amp, and they seem to both be working normally?
    The amp has no noticeable difference in sound level between which rca input I test when I tested them. Both RCAs connected is louder than one RCA out of the set.

    Do you think I should open my amp up to look for shorts? (I dont really think there is a problem there)
    Or do you have any other suggestions I should do?
