JBL soundsystem help needed

[nhalljr]

I have a 98 Mark VIII with the premium sound system (JBL speakers, Cassette, CD changer in trunk, etc.) What I need to know is if this car has an external power amp. I am changing out the headunit and the new headunit has both speaker outputs (to attach directly to speakers) as well as preamp outputs (to use with an exeternal power amplifier - like the 95 Cartier Town Car).

Anybody know if the Mark VIII LSC with premium sound uses an external power amp system?
