Question about UDPs and Amp

[vidmaster]

I have a pretty hard hitting setup but it makes my headlights and gauge lights flicker when I crank it up around 30% volume and higher (I usually don't drive with it at that volume though).

I was planning on adding a capacitor later on to help out, but would adding underdrive pullies on this setup be ok? Or would the underdrive not allow the alternator to kcharge the battery fast enough? If not, would adding a cap to the audio setup allow me to get the UDPs?

The gains for the UDPs for the price and ease of installation rock and I'll be sad if I have to choose between the system and the UDPs

Another quick question, if I'm getting a chip, I do not need a timing adjuster since the timing can be adjusted through the chip right?

Thanks in advance guys.

If you are adding pullies get a capacitor. I have pullies and my battery gauge goes to the "O" on normal when I'm in drive. When my bass hits there is a slight flicker at night when my lights are on. I have a small setup with an audiobaun 10" so I'm gonna get a 1/2 farad cap. With your setup get a 1 farad cap.
