Well! I almost have the system finished in the wife's car.
I just got done putting in the head unit
AVX –P7300DVDIt’s a CD/DVD/TV tuner

It motorizes out when the key is turned on

And I also installed the control unit
AVM-P9000R(Dolby Digital/dts surround ) AM/FM tuner also

The amp went under the seat,notice the 4ga power & ground

There is a 10” Rockford Fosgate woofer.

There are Eclipse 6.5” in the doors along with tweeters in the front pillars,
I also put in a center channel speaker below the headunitThe 9000 brain has true Dolby/DTS digital 5.1 through fiber optic cable (6 channel)

All I have left to do,is upgrade the subwoofer amp and the rear speakers need to be upgraded.But I’m pretty happy with it now. !
(btw,I put it all in myself)
