I want to make sure that i make the right steps to supply everything and not have to worry about stuaff breaking

Should i get a high power alternator more batteries or am i fine? i have no clue,
PLUS!!! If i do get an alternator, who makes one for an 06 HHR? this is killing me please help!!!!

 

Just get a capacitor. My old Grand Prix had problems powering my (then) 800watt system and I was told to get a capacitor, but didn't because I got rid of the car soon after :P

 

get a higher output alternator. You will need it. Also replace fuse in trunk near battery. You will need to replace it with a higher capacity fuse. They sell what you need on Amazon
