Audio Systems: wiring problems, rockford amp, fosgate amp

Question
Yes my name is bon myers the question i got is i have a 1993 cadillac sedan deville alot of our local audio shops will not mess with cadillacs well the problem is about a week ago me and my brother in law hooked up my system which consists of a 10" bandpass alpha sonic sub 600 watt rockford amp a (dual) name of cd player we have hooked everything up right so we thought but now my battery keeps drowning over night could this be caused from my 12 volt from my amp connected to the factory wires instead of to the battery itself hopefully you can help me thanks BON MYERS

Answer
well first off. when you say "The 12 volt to the amp", I think you mean the positive and negative power wires to the fosgate amp? you connected them to the factory wiring?  that's going to be bad on so many levels!  the fosgate amp will draw ALLOT more power than any factory wires can handle so you MUST run a fat (8 gauge or so) power wire to the car battery and a matching (8 gauge or so) wire to the body of the car for ground.  it must be grounded properly (drill through car in solid metal, sand off paint, use heavy bolt etc)
now the amp has a wire on it usually called "remote".  this wire is what triggers the amp to turn on and off.  if you wire this to a source of constant positive power, then the amp will never turn off and drain the battery.
the new dual headunit that you installed should have a remote wire on it that you can run to the amp and connect it to the remote on the amplifier.

your amp should have a little power light.  watch this when you shut the car off,  the light should go out after a min or so.  if it doesn't, its staying on and that's why your battery is dieing.
