Power off the battery.

[TheDanger2801]

This may be a dumb question but, I currently have 2 halogen fog lamps and my sub woofers amplifier both tapped off my battery. The fogs are wired with a relay taping the battery and the headlight wire and the amp is directly off the battery with a inline fuse. I plan on putting two 100 or 130 watt lights on my ladder rack just wondering if i can wire them the same way i have my fogs wired with a relay to the battery and the headlight switch or if that is to much draw from the battery?

i have 4 kc's and a 200 watt amp and mine is ok you just have to watch running them at idle for long periods. you can always get a bigger alternator for about 200$
