Default voltage drop

well I have done the big three and have a new battery (~1month old), and I have been getting some pretty bad voltage drop with only 800watts. Just wondering if this is normal with a stock alternator and would there be any way to help out with the dimming? btw i got a PA a2400db amp

If you mean 1800w(which I believe you do)..then you might need to look into a HO Alternoator. I would say 1200-1300 is about the maximum you can push on just the big three without dimming...

well yea its a 1800 watt amplifier but I've got the gains set at 800 watts set with a dmm.

thas right
maybe he means he has the subs wired up to where he is only getting 800 watts to them. and he has the gain turned down.

yea I have the gains set to 800 watts on a 60hz test tone with a dmm. Im thinkin its my ground but I can't do much about it now its pretty nastyout.

see that doesn't make any sense to me... Because if you turn the gain down, less output which means less power consumption right? the amplifier isn't constantly consuming its max power correct?

its called a clean signal, and a clipped signal, i believe.

power is created by the ohm load at the amp.

are your subs wired at 4ohms, 2, 1........8?...?

yes blazing loud is right. your power depends on your ohm load. what subs do you have and what ohm load they wired up at
