JL reps have told us that their HD amps are the platform for data communication. There is some discussion privately about how BIG this will be. Both for JL and/or their dealers to see what the amp has been through (when that kid leaves the shop and goes for a screwdriver to crank the gains up), tempuratures, moisture, etc. Also-would make it easily possible to "lock" the amps-similar to what Directed dealers can do with the Bitwriter on the DEI (Viper, etc) alarms.
It would hopefully be tunable, adjustable, etc through use of a USB connection to a laptop. We'll see. This is VERY close on the horizon...
