finally beating
Cap will help keep the voltage constant but pulling that much power hes going to need more. Im only pulling ~900w system + hid kit and i get dimming really bad with 1 farad cap. My battery is 4 yrs old and ive killed it a few times so im going to have to find a solution myself.
Like I said, deep cell battery and upgrade the grounds will fix it. I'm nearing 2000w RMS and have no dimming of my HIDs or anything like that.
