From a newbie starting point, is there a guide to how much amp power for say a single 12" is a good starting point? I've had 400rms before and could have done with more, will 800rms be noticeably better? Need to jump to 1500rms?
If my alternator and car is fairly new and decent, when do I start needing to do extra power upgrades/capacitor etc. would this be around 1500rms+ generally?
Lastly, if I got an 800rms amp, and the single sub is rated around 600rms this sounds like it should still be ok if gains are set correctly? Would I configure the amp gain to 800rms or limit it to 600rms?
