What is a good second battery?

I currently have a Kinetik HC1400 under the hood with a 165amp alternator.

I have an Orion 1200D running two alpine type-r 12s and a 4-channel 50x4 at 4ohm running the speakers. I will eventually upgrade the 4-channel to something that does 100x4 at 4ohm. Currently, my lights dim after turning the volume pass 28. I have the big 3 done with 0 gauge wires and just upgraded stock battery to the hc1400 and stock alternator to the 165amp one.

What is a good battery that will just do for me? I'm thinking about another Kinetik brand battery, how about the HC2400?

Also how should I wire the 2nd battery? Should I run a positive 0 gauge from the first battery to the positive of the second battery as well as put another fuseholder to it?

Thanks

 
dang your lights are dimming with all that? i would make sure your grounds are clean man. also, from what I have seen use your second battery as a distro block. in line fuse up front pos. and an inline fuse in near the back battery is the best way. then just ground out the back battery and you should be golden. but if your running just 1200 rms i don't know why you are having voltage drops with your current setup. my friend has two kicker solo's l 7's with a 1500 rms kicker running off of just a yellow top and stock alt. no light dimmage. check mamke sure your grounds are clean
