Lights dimming to bass... Options

[lilguy]

Hey all with my current audio setup when there is a high bass beat on each beat (doof of tha sub ) all the interior and headlight will dim slightly...

Currently have it set up:

Headunit (50x4 RMS)
powers: 6.5" 3-way speaker 55 watts RMS (back speakers)

600 watt 4chan amp (75x4 RMS at 4ohm, 100x4 RMS at 2ohm, 195x2 RMS bridged at 4ohm) powers: 6.5" component speaker splits 70 watts RMS (front speakers)
and 10" subwoofer 150 watts RMS (boot, through LPF)

900 watt monoblock amp (240 Watts RMS at 4ohm, 350 watts RMS at 2ohm)
powers: 12" subwoofer 250 watts RMS (boot)

Now doing a little reading and what i have gathered that will fix the problem is a Capacitor?
and from what i have read about them for ever 1000 watts of amps i need 1 farad.
So for my current install id be looking at 2 farads to be safe, but im also looking at getting another of the 900 watt monoblocks and the 12" sub to replace the 10" so that would be 3-4 Farads to be future proofed...

I have looked at some capacitors and they seem to be big $$$ and then some that are only $90-120 is there a difference in them, will they cause problems or are they the same basic thing?

Thanks all and if a capacitor isn't the solution what is?

Well since that isnt too much power to the amps, A cap may help, but i couldnt guarantee it
I have a very power hungry amp now (4000w) and I had a 5 farad cap with it and it didnt do a damn thing. And I had that 5 farad cap with my old system that was 1500W (plus the headunit) But honestly it still dint do much, they are designed to take a few bass hits and have to recharge (they have very fast recharge rates)... but if your listening to good bass songs, it doenst get a chance and just stays down and ur lights will still dim.
What I suggest is a Kinetik battery (I have one) and the cheapest one, you can find for around $150. And has more power than a 100 farad cap (whether that is 100% true idk) Its designed specifically for audio, just like a giant! capacitor

Highly recommend doing a Big 3 as well. Just look it up you'll find all the info you need, which will allow for a better connection, and less voltage loss.

What you really need is a highoutput alternator Mines very top notch but there are ebay ones for like $250 and will put out double what the stock alt will, at driving RPM's. The alt is where it all starts and with a stock one, your only "cushioning" the bass blow, ultimately with out it your car, or battery can only charge as much as it can... if that make sense.

anyway ive done countless things with audio, and used to be really really into it, so have alot of useless info further than this if you need to know something just ask
