I have one run of 4g to my 730wrms amp, with big three done in 4g, but I'm still dimming really badly. im almost positive its my batt, but i haven't tested my alt yet.. anyway, which of these batteries should i get (to replace stock batt):

kinetik hc 1400 - ah:60

amps: 1500

kinetik hc 800 -- ah:36

amps: 950

or something else that will hopefully solve my dimming problem? i dont know much about batts, any advice would really be appreciated. thanks to all.

Is this going to be your starting battery/only battery? Also, have you looked into Powermaster?

check out this battery

thats weird...i have 1000 watts and my lights dont dimm at all...but anyways you should try powermaster battery's

i get dimming off 800 but my batt is going out lol... time for a new one

id say go with a bigger alternator

Yeah this will be my starting/only battery. my alt is 120a so i'd imagine it will get the job done with only 600 watts. how many amps do you think i should get in the new batt? and what does the ah rating mean? i like powermaster's prices btw thanks

Get your battery checked and replace it. I have 1000 watts in my car, with a (small) stock battery and a 90 amp alternator.

AH=Amp Hours

for a cheaper alternitive Id look at the Exide/NAPA Orbital very similar to the Optima Red top

now that i think about it, would it make more sense to wire a second smaller battery that would just power the amp alone? i have plenty of cranking power, so should i just get another cell in the trunk? how many amps would i be looking at for a 600 rms amp?

~60 amps. The more the better though.

My lights dimmed. Got a capacitor! Stock electric... Idle is 14.9 volts and when running never drop below 14.5... Capacitor helped me a lot in my case. It isn't nearly the same w/o it. Took it out for a while and my voltage suffered... I'll get flamed for mentioning it, but it really worked for me and I got the voltage to prove it...

huge ass cap^^

i got a Kinetik Power HC1800 and i love it i would say the hc1400.

i'm pulling like 1600

check the link i listed before. good battery cheap price. also with an alt that big even without a batt id dont think you should get dimming. i have a 140alt stock amp and a yellow top running 1200w and not a bit of dimming even at full tilt at idle. your alt is probably going or you have a bad wire in your charging system. if you dont properly charge a battery it will kill it so get it checked.
