Odd question concering diming lights..amp power and what not

[FineLinePimpin 10+ year member]

Ok so my last setup was a ED nine.1 at 1ojm pushing 2 skar ma8s....so about 1200w...my new setupsis one IAD Reign 12 on a Audio Technix 800.1 at 1ohm...so 800w. Now on the old setup the headlights would noticeably start to dim with the volume at around level 22-24....now on less power it does the same thing around 19-22. I know its not much and yes I'm on a stock electrical system but it was making me wonder....is it amp draw is higher even less power?...is it a less efficient amp? Just wondering.....it may ne a dumb question but oh well lol.

could be a few things:

bad ground

clipped signal

less efficent amp

RD's are fairly efficent and IDK about the AT tho.

weird, check fuses and batts voltage

fuses really have nothing to do with what he is talking about... and obviously he's gonna get slight voltage drop if he has headlight dimming

more than likely a less efficient amplifier. first check all of your connections, making sure you are using appropriate gauge for the system, (a little bigger then reccomended wouldn't hurt) and make sure your grounds are solid. if you still have this problem, you will have to at least upgrade to an AGM battery

All the wiring is the same as the 1200w ED amp...just swapped out amps and the gauge is heavy enough. I figure its just a less efficient amp and was just one of those things I was thinking about sitting bored at work lol.

do the big 3, it'll improve efficiency, also get an AGM battery
