Ok so this is what I have, 2 kicker 2 ohm dvc 10 inch L5s,2 alpine m-500 amps for the subs, My lights do not dim whatsoever with only one sub running. But I want to hook them both up with their own amp. I’m sure this will dim the lights. So should I hook up another battery in the trunk?or use a cap? And if I hook up another battery should I run both subs off the secondary battery or one off the main one off the secondary. Also do I need a special battery for this or can I use a deep cycle battery as I have a brand new one from my boat. Thanks in advance for any help

twalker is right

I had a single jbl gtx  and was sure a 2nd would dim the lights    I hooked up the 2nd

once I stopped clipping  I dont dim the lights anymore and my alt  is 80 amps

What ohm load You gonna run with 2 dual 2ohm subs it’s either.5 or 2ohms. At half ohm I doubt your amp will hang and go into protect and at 2ohms your loosing half the power on your amp .

ok  what car is this??  what amp is your alt?  

do the big 3 in as heavy of gauge you can afford,  0g ofc is recommended

run 4g power minimum  4g  ground   ofc

like I  said I have a pair of jbl gtx at 2ohm  on skar vd-10 and with one it was fine and with 2 I am still fine   maybe a slight dim at idle at max output  but its not enough to worry  me I see  my volts go  from 14.1 down to 13.5 then bounce up to 14.3 and settle back to 14.1  this is  at night  during the day its less

my truck idles at 500 rpm (supercharger drags it down) and a stock 80amp alt  (which is considered the lowest output standard)     if you are concerned get a  big battery and quality connections

I don't think those amps are 1 ohm stable.....so you're gonna have to run each amp at 4 ohms.

That's only a 600 watt draw....you'll be fine.
