Again Sry, for my english, it's not the song, it something else, i thought it was the RCA cables, and i changed it for Monster Cables, but the problem persists; its a very strange problem, the audio sounds well, but in some point (not always the same point) the bass decrease, and its with various songs, i cant figure out how to describe it; it just like if you were listening some song, and suddenly your bass go out, but after a few seconds it returns, and after a few more seconds, it go out again, and like that :help:
I dont know how to describe it, just a thought do u thinks it has anything to do the Remote wire?, or the Ground wire? i know both AMPS r not turning off, they remain always on, so i dont know what else might be.
THANKS FOR ALL YOUR HELP, and Happy Holidays!!

checka ll your wires.... its not the remote if the amps stay on. i'd check on the power, ground, speaker wires.. make sure there all securely screwed in.

and i changed it for Monster Cables

Those cables would sound the same as say wal-mart RCA's, your just paying for a name right there.

the bass decrease, and its with various songs, i cant figure out how to describe it; it just like if you were listening some song, and suddenly your bass go out, but after a few seconds it returns, and after a few more seconds, it go out again, and like that

What kinda car are you driving? If say you have a honda civic, with an 80 amp alt, When listening to your system does your lights dim badly? If so, I'm sure those two amps are pulling about that much. You should upgrade your electrical system. I'll let you know that sony isn't to reliable. You might want to lose that inferior equipment.

Hmmmm, something telse me its a bad grounding point. Where is your ground wire connected, and how?

after you run your system for a while and the bass decreases check and see if your cables are hot like the ground at the grounding point. if its hot then you have a bad ground.

That or just shake the wire as your listening, and see if the sound changes.

Does the bass totally turn off, or just decrease in volume?

could be improper impedence at the sub amp also.....if the impedence temporarily drops below that of the amps ability it could do what you are describing........
