When do you have to start considering an HO amp?

[taosd 10+ year member]

I am going to be getting a new vehicle ( a fairly new vehicle, made in the past 4 years, a mid size sedan or an SUV) in the next little while, and I want to run an amp that puts out about 1000w RMS (thinking of getting 2 JL 12W6v2s and a Memphis st1000d or a JL 1000/1.) I will likely also, down the road be making a carputer using a tablet PC. finally, I might, down the road, install aftermarket speakers into the doors, and utilize a four channel amp that will put out around 70 - 90w RMS per channel. My question is will I require an HO alternator, or even come close to requiring an HO alternator? I really don't want to cross that line of requiring an HO alternator.
