Will I need a battery?
 

So I am almost ready to put my sub in and I am not sure if I should upgrade my battery before doing so. I am collecting up the supplies to do the big 3 right now so I will have the big 3 done. I drive a 08Civic coupe with the stock battery being 410CCA.

Well if the battery is OEM, it's still a fairly new battery. I don't think you will, unless you start putting some serious power through the car, then you may want to.

Well I am running 80rms x 4 off one amp right now but the RE sub I have is rated for 1000rms @1ohm so I am thinking that's going to make my lights dim.

It would be nice to have a secondary battery because those hondas dont have a very strong electrical

stock alternator is 90amps and the stock battery almost a ride on tractor battery size, I was thinking of getting a battery box and putting a small yellow top in the trunk.

Well I ended up picking up one of those Exide batteries from parts source and managed to stuff it under the hood.
