So I noticed my lights are dimming a lot harder than they were. Also it sounds like my car is struggling to start after a day of just sitting, I think the batteries going bad could just be the subs draining them though

Can I get away with just replacing the battery to solve this, or would I have to do it all?

I was looking at something like this, not sure it would fit though http://www.sonicelectronix.com/item_88293_Kinetik-HC1200-BLU.html

or could I just go to autozone tomorrow and get a battery from there?

kinetic is overrated. xs is just as good and may cst cheaper depending on vendors in your area.
first off have your bat checked before spendng any money.
also whats your system wattage size?
may be running into alt probs as well.

Yeah that's what I'm afraid of should I just get battery tested

Do the big 3. It will help some. If you aren't putting a battery in the trunk juat get the biggest agm battery u can fit up front. Marine batteries feom walmart work just as well.

your probably needed a new battery. agm tho and or new alt. along with the big 3. id do as suggested above but if your car is struggling to start after sitting your battery is probably about done for. and not holding a good charge.

i'm not trying to do alternator and wiring as well, would just new battery solve this you think?

Get battery tested. If its shit buy a new one and do the big 3. The way your questions are coming out i assume you're not running more than 1k rms (not trying to be a dick)
Just replace and upgrade. Worth in long run
Definitely do the big 3 if you're worried about charging issues

Autozone can check your problem for free. They always fix my stuff there

autoaone is garbage.

ive had a brand new alt fail and they tested it and said it was good. i said test it again and again and the guy tried to argue with me about how their test showed it is good. i said load test it again and sure enough bam bad alt. they are noobies in the car industry and never get ANY advise from them.

get 150 alt, +seperate battery for each app, cap, 0gaguewire
