I ... NEED... to upgrade the audio in my 1999, 911. Unfortunately, i only
have room for 4 x 4" component speakers, an amp and a deck - no room for a
sub. The advice i have so far leans towards a new Deck, Amp and Front two
speakers. But i was thinking of keeping th factory deck and adding an
Audison Amp with four Focal 100KP speakers.

Any comments or advice?

thanks,
gp
