Quick question: When ur speakers are wired in stereo instead of mono, are they supposed to hit at different frequencies? Mine do. One is lower and one is higher.
Speakers? Are you talking about subwoofers or mains? If subs and you have two, one conencted to each channel of a stereo amp and they sound different, then either it's the setup or the woofers. Are both channels of the amp receiving exactly the same signal? What are you using for a crossover and how is it set? Is there any electronic processing in the signal chain? If the problem is in the speakers, are they both connected in exactly the same way to the amplifier with equal lengths of speaker wire? Are the voice coils wired in the same ways? Are they both in equivalent enclosures? Do they "share" airspace in one enclosure? They might just be cheaply made and have different sounds one from the other. If you're talking about mains, the same observations apply.

Support the12volt.comNope, they shouldn't. Only thing that would cause that is if you have music playing where the music is actually set up to play one thing on the left and one thing on the right (this is what "stereo" really means).
If you were using an RCA output that wasn't mono (in other words, not specifically for subwoofers) then the RCA output may be stereo. This would cause your problem. Try different songs. If they always do this, you may have a bad voice coil in the speaker, you could have a pinched RCA cable somewhere, you could have a problem with your amp somewhere...the possibilities are endless. Probably the speaker though.
If your RCA output is not made for subs, then it's usually best to try and wire the speakers mono to the amp (bridged), otherwise the speakers will hit at different times on some songs and they will be half as loud at some points!! Best to use mono, but make sure your amp can handle the ohm load first!!
