Ok so my buddy has an 2.0 fared cap and he bought it from craigslist it powers up fine. But his lights still dim while hitting hard with the subs wired to 2 ohm .. he didn't get the charging bulb when he bought it. So he just hooked it up.. could this be why its dimming because he didn't charge the cap?? I read u can use a turn signal bulb to charge it..
