[QUOTE="Jeffdachef, post: 8179228, member: 650438"] realistically your car's stock alt should handle up to 1500-2000 rms if you have upgraded your big 3 (adding bigger earth wires in your engine) and add an AGM battery in the back or upgrade the one in the front. A daily system is not going to pull that much amperage all the times and AGM batteries have enough reserve capacity to keep your voltages moderately high and safe. Unless your competing in SPL then thats a different story. Plenty of people have ran 2k systems on stock alts with no trouble at all as long as your voltages are high and stable you should be good. That being said with the amount of space you said your going to use, i wouldnt go for subs higher than 1000 rms since those tend to want more RMS than needed and need big enclosures. The amp is pretty important, make sure you have a bigger budget for your amp rather than dumping it all on subs. Also your going to need sound deadening for sure. [/QUOTE]
