Dumb ?

[notmade 10+ year member]

sorry for the dumb question but I want to make sure,

when i had my system installed the shop i went to used 8 gauge wire instead of what was supposed to be 4 gauge, but since they already did it i just got my money back and forgot about it. but now i have run into some 4 gauge wire and was wondering if i could just take out my old (8 gauge) wire and replace it with the 4 gauge? or is there something else i will need to do?

sorry for the ? but ive never installed anything in cars

yes, just replace it... but make sure to replace the ground wire with 4 gauge as well... what's the inline fuse on the 8 gauge rated at?

well my friend that im getting it from has it in his car that just broke down and said i could go take his wire if i wanted it, so im guessing he must have the 4 gauge ground wire since he had a system right? and im not to sure what the inline fuse is rated at

if he doesnt i have some extra 1-1.5ft of 4ga wire, just pay for shipping and paypal fees, and 1$ for gas to the post office. there's alreayd a terminal attached to the otehr end too.

well i went and got it but im not sure where i would find the ground wire. he has a piece of the same 4 gauge screwed onto a piece of metal in the trunk that is just hanging there, would this be it??

yes, that would be the ground... and find out what your fuse is rated at, i believe the last time i ran 4 gauge the fuse was 80 amps... very important, the old 8 gauge fuse may be lower, like 40 and this will be bad...

anyway you can tell me where to find this rating at?? appreciate all the help

says it on the fuse itself

the main power wire, the old 8 gauge, should be ran off the + battery terminal under the hood... somewhere on that run, close to the battery there should be a fuse holder... open it up and see whats inside... usually within 18" of the battery

follow your power wire till you hit this thing covered in a plastic casing. should be under your hood (if only 1 power wire straight to 1 amp), or somewhere in your trunk, connected to your power wire
