Hi -

Just traded by 2002 4.4 on a 2006 4.4... however, the audio quality in my 02 seemed much better. Both have DSP (the 02 didn't have NAV), and both spec sheets pulled at the dealer have Premium HiFi listed as options

Notably, the bass and midrange was tighter on the 2002.

In speaking with the dealer, he said there is actually an audio option BEYOND Premium Hi-Fi that added more concealed door speakers, rear speakers amplifier output, and subs. He believes that my 2002 indeed had the Premium-PREMIUM Audio (even thought its not on the spec sheet), and not just the Premium Hi-Fi.

Am I making any sense?

My 2006 indeed has the 2 sub speakers behind the passenger trunk panel.

GOAL: to determine if there is indeed a more premium audio option. If not, I will assume that something is wrong with my current system.
