I have a alpine headunit with 2 JL audio subs and a pioneer amp when i turn up the radio I notice my headlights and dash lights have slight pulsating look and I know some people with say to throw a capacitor in it but I've done research on capacitor I've read many thing that say there just not worth it anyone got any suggestions or thoughts? (And I don't want to turn the radio down)

No one should tell you to add a Capacitor. There is a few things you can do till the problem gets fixed..

1. Turn down your Gain on the Amp.
2. BIG 3
3. Upgrade Stock battery to a Larger AGM battery
4. Add 2nd Battery
5. Upgrade Alternator

But before you do anything. What Amp do you have? Whats your Gain at? and how are your Subs wired?

Post up what Amp you have and what Ohm your Subs are wired.

The BIG 3 is...Try the first 2 first. Cheap and easy..

1. Upgrading your Battery Ground by adding a 1/0 Ground.
2. Adding a 1/0 Ground to your Alternator.
3. Adding 1/0 Power from Alternator to Battery

You can either buy this kit..

or Make your own from 2/0 Gauge Welding Cable. I say 2/0 because most good Audio Cable is oversized. That Mechman man is actually closer to 2/0..

Go through my Audio upgrade thread here. I'm going through many of your questions in my thread.
