[QUOTE="seatslayer, post: 4583651, member: 592309"] Hi guys I live in south africa and have a brand new Seat Ibiza, not sure if you guys get that car over there but anyways i need to upgrade my alternator currently i think mine puts out between about 75-80 amps the guy i spoke to said he can upgrade the alternator, he doesnt garuantee that it will definatley put out any more power but if it is succesfull it will only be about another 20 amps or he said i can get another alternator that puts out about 120amps but then it may not fit and they would need to put new brackets and all that sort of thing in. [IMG]//content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif[/IMG] but i need to know if another 20amps would do it for my system or do i need the alternator with 120 amps and will that even be enough? below is what i currently have in the car i have no idea how many amps it is using or how much it needs exactly? all i know is that my lights dim at the moment on the heavy bass notes and i presume thats not a good thing for my current alternator. 2 x 12" Vibe Black Air II 12" subs 550wrms 5000w Class D monoblock amp Pioneer 6 x 9's 400w Massive Audio splits in the front 1.5 farad Vibe Cap At the moment the splits and 6x9's are run off the deck but i have another amp - 2ohms RMS Output: 150 x 4 - 4ohms RMS Output: 90 x 4 that i will also be connecting but i dont want to do that till i upgrade the alternator as i'm scared i am gonna fry it? could someone please advise as to what sort of amps i am probably currntly pulling and what i need? Hope that i explained enough thanks [/QUOTE]
