horrible dimming lights

[pablo4429 10+ year member]

ok so i have a kicker 1000.1 and 350.4 bridged to two channels, so like 1300rms or so, and i ran like 15 feet of 2 or 1 gauge, it wasn't marked. both power and ground are in the same size. where would be the first place to start looking to improve, grounds? the big three? would a bad battery cause some dimming too because my battery may be on the out. i think the stock alt is like 105 amps so about 40 at idle but it was dimming at 2000 rpm bad.

i shouldnt have to get a new alternator right?????

any help would be great all

thanks

do the big three.have you try putting a capacitor bud?i think you need more powerful batt,as far as i know your alt is good for that demand..

40 amps @ idle sucks for that much power...I would start by upgrading the big 3 and see what you voltage is at the amp when you're done with that.

DON'T waste your time or money on a cap

yea im nto sure exactly what idle amperage is, i just saw that somewhere

so a bad ground wouldnt cause dimming too?
