How many watts can I run on a stock electrical system on a civic?

Looking to run 250 watts total for my comp speakers(hsk 165s), and possibly 500 watts to a subwoofer in the rear(hertz hx 300 or jbl gti). Should I be ok with my current setup?

I'd say yes, probably pretty easily. What year civic? I'm running around 900 off my stock 4cyl accord (02) and have no problems at all.

I've ran more on stock electrical with no problems. You'll be fine.
