Hy guys

I plan to install next summer in my car a bone stock(no electrical upgrade) Chevrolet cavalier 96 4dr:

soundream t5-12 and a hifonics BXi-1206D

does I need to change my alt, batt?

cap or BIG 3?

p.s. just to be sure 4awg isn't enough, I should go with 2awg.

thanks everyones who take the time to answers my question!!!

 

i dont think you will need to replace either, as long as your goin in with a fresh alt, and battery you should be fine. my other car i had was a 99 cavi and i pounded my system hard for a year straight and both my alt and battery held out. but by the time i sold my car i had to replace my battery cause it was dying pretty bad haha. hope this helped, peace
