door speakers/amp

02 prizm prolly same as 98-00 rolla but not sure. How do you take out the front door speakers? I popped the panel and it looked like i needed a real small philips head for 3 screws but i wasn't sure.

Also I have 2 12's. 1200watts peak. powered by a 2 channel 400 watt amp. I was thinking about getting a 1000 watt amp but then I thought maybe I could get a 4 channel 2000 watt amp and only use 2 channels and it would be powered by 1000 amps and leave the other 2 channels open? Then if i want to get a bigger system, i could jus hook up the rest instead of getting a new amp again?
