[QUOTE="JPIKE420, post: 8273762, member: 661314"] Thanks for the replies guys. I'll be running some pioneer amps, a 50 X 4, a 100 X 2, and a 600 x 1 in an 09 kia rio. I have one more question regarding fusing. How do I tell how many amps the fuse at the battery should be rated for? Someone told me that you can add up the numbers on the fuses in the amps and that will give you a good idea. I also found an article on crutchfield.com that said "multiply the power all your amps consume by 2 then divide by 13.8" so I did this and it comes out to be around 144 I think.
