    I use a 12V 3A AC to DC adapter.

    Leaving the complete system wired (6 speakers, three amps, one equalizer and one receiver) would like to play music through it while in the garage with the engine off.

    Could fade out all but one pair of speakers. A 1 amp maintainer would produce 12 watts so 6 watts a speaker (maybe allow for some current loss). The door speakers are supposed to produce 91dbl at 1 watt so there would be enough volume. But IhadA70z28B4 pointed out dc from a charger is not always clean. If there is any chance of damage to the components then I won't do it

    The car battery will smooth out any current fluctuations and hash. Listen close for any 60hz hum, if none you should be good to go.

    Running amps is the issue, especially if you have a sub. I wanted to run a big car amp I had in the house for a home sub but a proper DC power supply was real expensive.
    Sounds like it is time to hit up some local garage sales, get a "garage receiver" and a couple of speakers.
