Battery

[Pri]

At what point do you decide that your car battery needs to be upgraded? i've got the part number for a new high spec battery but i dont want to go out and buy one if my current one will cope with the new amps and speakers :?

a car is wired in parallel so everything takes 12v. if you find lights arent as bright around the dash at night when lights are on then this is possibly when you are drawing to much current and possibly an upgrade is needed.
