You should be okay with the big 3 done. You might get a little dimming at idle or when you really crank it up. Try it first, you should be okay.

orion 2500d @ 1 ohm, 2 x rl-p 12" only dims my headlights when i get really greedy with the volume, most cruiseing and bumping is problem free, in fact on my 880 prs there is a setting that displays voltage, if its accurate? my voltage doesnt drop below 14 even when bumping pretty hard, in a stock 1992 toyota previa minivan, 70 or 80 amp alt and regular battery.big 3 not done.

Yea I know.... dude, I got my AC on, my lights, and my system ata moderate level... no NOTICABLE dimming... IF u stare into the lghts [not recommended] then u might notice it. I was scared at first, seeing my cars' electrical was all stock.... but it holds his own pretty good so far

I say get the best outta the equipment you purchased...a better source of power will make any lackluster system worth having. Specially 1.5+

ofcourse, but that wasn't the question. To increase life, and output gettin a h/o alt, second batt, big3 and making dang sure that you have good grounds will work wonders, but i've seen orion 2500's running off stock electrical systems without major problems.

running a a1800db at 1 ohm, stock alt, no big three, just an extra battery and only get slight dimming at high volumes when at idle.

My 2500d and 8004 would dimm the piss out of my lights on my 90amp alt.

If you are running a stock electrical system with 1500 + watts, and get no dimming.

You are not really running more than 1500 watts
