This is more for an opinion than an answer, but how much power is too much on a car audio system? I have a 1200 watt sony system and it has enough power to shake my street. 
What's your guy's opinions?
man if you got the money there isnt such a thing as too much. i mean obviously over 15000 watts is a lil intense but some people want it. if you have no limit on money go really big. i can tell you right now that sony anything sucks. if you think that is hitting really hard then you've never heard a real loud system. go out and buy some solo x 12's and fully power them with 5000 watts rms and then tell me bout your sony xplodes. but if you dont want to be upgrading the alternator and the battery and stuff like that and just want to stick with just buying subs and an amp...stay under 900 watts rms just to be safe. its said if you go over your gonna need to be upgrading wires and electrical stuff so it all depends on your pocket book
