I know a lot of people don't like Sony, but what do y'all think of the following setup (on a budget):

Amp: Sony XM-DS1300P5 400W RMS x 1 @ 2 Ohms

which will push:
Sub: Sony XS-LD125P5 12" 400W RMS

Also, I'm replacing the factory speakers with:

6.5s: Sony XS-HD160G 50W RMS
6x9s: Sony XS-HD690G 60W RMS

I'm leaving the factory AM/FM 6-disc CD changer head unit because it's just soooo nice looking & convenient. We'll see how the factory head unit sounds with all aftermarket speakers, sub, and amp.

I've already installed the 6x9s and they sound much better. I've also already wired the amp. I'm just waiting for the sub enclosure to arrive to hook it up.

I'll be installing the 6.5s one night this week. I took the door panel off to check it out & didn't see how the speakers were mounted. There were no screws. Are they just snapped in place by the plastic encasing that the speakers are in? Do I just pry them out?

Has anyone else replaced all the factory speakers & added an amp & sub without changing the head unit? If so, how does it sound?
