I would like to know what type of amplifier I need to get if I want to power 4 speakers (2 front and 2 rear) and one alpine type 4 10 inch subwoofer. The 2 rear speakers are alpine type s series sps-600c but I dont know what the front speakers are. The rear speakers have a 240 watts power peak and 80 watts rms. The subwoofer has a 600 w rms and 1800 w peak power. I have no idea anything about car system.
