Danny,

I would look into the purchase of one of those small standalone recording mixers such as the little Behringers for this purpose rather than go through remixing every song just to make the laptop work. For one thing, you know the songs are already mixed correctly and therefore they won't be once mixed to be louder on that lappy. For another, the sound may be loud enough once that's done, but the gain staging will still be wrong, can't avoid that with what you intend to do.

You can find one of those little mixers for under $30 these days.

The reason I suggest the use of the little mixer as a Line Amplifier into the PA is that a standalone Line Amplifier costs a lot more than the little mixers do, likely because of supply and demand issues. But the mixer can indeed be pressed into service to do the same thing as the Line Amplifier.

Another device that could be used here is the Active Stereo Graphic Equalizer, such as were popular as home stereo and PA devices. Most of them can deliver 12 to 15dB of gain, which should be plenty.

Adjust the signal, not the separae files, as it is the signal which is down, not the files.
