what size cap should i get for....?
 

an Audiobahn A8000T mono amp pushing 2 Alpine Type E's at 800 watts total and a Kenwood 45 watt X 4 channel. Im also going to be adding a JBL 50 X 2 soon for my tweets and i am upgrading to a audiobahn 4 channel (50 X 4) for the satellite speakers. So all in all ill be pushing 1100 watts total after everything is said an done. But i need a cap NOW cause my headlights dim a lot when the bass hits. I was thinkning a 1 Farat cap should be enough but do u think i should get a bigger one? I dont plan on getting a bigger sub amp at all. These type E's hit really hard. Thanks in advance

A 1 farad cap sounds good for the sub amp...

How many watts is the Kenwood 4-channel and the Audiobahn 4-channel amp? If they're under 500 watts each, you could get a 0.5 farad cap for each 4-channel amp... but you most likely wouldn't need a capacitor for the 4-channel amps.

Might want to also consider investing in a hi-amp alternator... 1,100 watts is alot for the stock alternator to handle.
