Do I need a cap or bigger alternator?

[Aces_Full 10+ year member]

I have a 2004 Silverado ext cab, only one amp. (Memphis ST1000D) wired at 1 ohm. I'm getting headlight dimming only on heavy bass notes. It's a noticable dimming though, that only lasts briefly. I've heard quite a few negitives about caps, but also heard a few possitives. Would a 1 fared cap solve my problem or only bandaid it. Is a bigger alternator a better solution? Thanks.

Your charging system can not sufficiently keep up, thus your lights dim.

A cap is not a "power source" as it rely's on the charging system for it's power.

Your charging system is allready struggling.... Why add another load?

You can not go wrong with a bigger alternator. More current on demand.

Upgrade the source.

Any ideas on a good place to start looking for a alternator?

A lot of SPL guys use them. Even Team Gates.
