Hey people with subwoofers!, Does this happen to you too? Options

Okay so Im driven home and its night and so of course I have the head lights on... Anyways, Im driving home and I throw in some music and a song starts up and the subs do a quick low rumble...

I driven a long and when that first beat struck, I noticed that the head lights dimmed with the beat... Then after that beat, the head lights went back to normal... I was like "Huh, thats weird..." and I threw in some rap CD that has a ton of bass bumps in it... The head lights dimmed with the beat...

The dimming is very slight too... I've never noticed it! But awhil back, a head light went out, and when my dad fiddled around with the head light, it lit up... Im thinking that the subs could be messin with the wiring or bulbs in the head lights... Or maybe my subs are a lil more powerful than i thought...i dunno

But yeah.. Has anyone else had this happen?

You do NOT need a capacitor, that will not help you. As shadow said, it will just cover up the problem for a while, and in the meantime will be a waste of your time and money. You need to make sure that your amplifier is grounded properly, and your grounding points in your engine bay are close to perfect. You shouldn't have a ground that reads more than 0.5 ohms; if one does it needs redone. If that does not help then upgrade all your grounds to at least 4g wire, and make sure the connections on the terminals are solid. If it is still bothering you then you need to finish with the big 3 and beef up the power cable to the alternator.
