Excessive voltage drop with bass hits/lights dimming. For a 1000w rms mono (12" sub), a 300w mono (10" sub) and a 300w 4 ch (front door/high mounted tweeters) do I really need to do a big 3 upgrade (160 amp alt now) or will just a 1-2 farad cap on the 1k mono help? I'm working on a tight budget and not planning on getting too crazy about SPL in the future, more concerned with SQ.What's the issue you're trying to solve with a cap?
What kind of battery do you have under the hood? The biggest agm battery that you can fit will help. I'd get your alternator and battery tested before i bought anything though because honestly you're not running much power and stock electrical should handle it without a huge voltage drop.Excessive voltage drop with bass hits/lights dimming.

I had a brief encounter with capacitors. I purchased one that had a voltmeter attached to the top. It was pretty, but useless. I eventually discharged it, gutted it, left it in place and used it for the voltmeter. As previously mentioned, your system should work with stock electricals.Hi all,
I'm looking for a budget friendly 1.5-2 farad capacitor near Southwest VT.
I haven't had to worry about batt performance much before now so probably weaker than it should be. Do AGMs charge/discharge quicker? I've just always heard one of the first things to add is a farad per 1000w for power issues.What kind of battery do you have under the hood? The biggest agm battery that you can fit will help.

If your have an old style lead acid battery than an agm will be a big upgrade and your current battery very well could be the problem, a cap wouldn't fix that. Still get the battery alt checked before buying anything thoughI haven't had to worry about batt performance much before now so probably weaker than it should be. Do AGMs charge/discharge quicker?

So, are your lights flickering or dimming? Flickering beans they are going on and off, while dimming just means they are... well... dimming when the bass hits.Excessive voltage drop with bass hits/lights dimming.

Kyle,Before you drop any money, look at some real-world reviews and tests of caps in that range.
Preferably reviews and tests by people who don't stand to make money off of you purchasing one (through affiliate links, etc)
For example, one test done with an amp dyno found this:
