Electrical draw question

[Peter Coomaraswamy]

I am hoping to mount some Bluetooth nav/music/phone components plus two gauges in my coupe. The gauges will be permanent but the tablet, phone, ipod and JBL speaker will be removable. I have most of the look and feel "mapped" out in my mind but these devices require power and I'm wondering if I can use a single hot/ground such as a lighter socket to power all components, and the only reason I mention the gauges is that if I were to operate all these devices with the lights on-as in evening cruising-with the A/C going- would I create an excessive drain on the alternator/battery? If so, is there an up-graded alternator I should install and will the standard 650 CCA battery be sufficient?

I'm not a very "electrical" person so I hope I can understand any responses.

Thanks in advance,

eBay has upgraded alternators with 80 or 100 amps, an auto electrical shop can probably do the same thing. Be aware that our coupes came with an upper M10 mounting bolt, sometimes before the b35 it switched to M8.
