This looks interesting!

This looks like an interesting option for those with non-removable OEM stereos who can fit the empeg (or other audio source of choice - if you must slum it) elsewhere.

It performs reverse-equalization to OEM outputs after being fed a calibration signal (disclaimer: I've not used one - this is regurgitated marketing spiel from the above link) and has a switchable (via toggle/master volume knob control) AUX input.

It sure was new to me, apparently out this month. Glossy marketing goo here.
