Electrical system dilemma

[937DYTBOI 5,000+ posts]

Ok, ive pretty much done some research and kinda came to a conclusion of what i want to do with the system. Im going to do a big three off of the stock alt on my 99 honda accord, i believe its an 80 amp im guessing. Ive decided to wire my Orion 2500d to .5 ohm so i dont have to send my subs back to get reconed to a 4 ohm setup. Setting my amp to .5 ohm will put out some serious wattage, so im kinda stuck in a tight spot thinking will my electrical might not do the job. I have a red top under the hood and in the trunk.

Do you think it should be fine? ive seen the prices for a HO alt and im jus not ready to upgrade that yet but the big three isnt that expensive.

I jus dont want to starve my electrical system of the power it needs, not sure if i will be providing enough. BTW im powering to 12" RE SX's.

an 80 amp alt is not enough. the money you spent on redtops could've bought an HO alt //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

would a 160 amp be good to get. How should i determine how much amps i need out of my alt

Im thinking of getting it rewonned i guess thats right. But locally they can do it so i will see how much they charge, Does modding the OEM alt affect anything performance wise and the longevity

generally a rewound alt don't last as long. i recommend just saving and get a 200-250 amp alt.

I am in the same situation. Trying to get over 2000rms into my car which comes stock with a 130 amp alt. Personally I just think upgrading to atleast a 200 amp alternator will take care of everything. I am going to go with 300 amps just so I never have to worry about it again.

OK ive been doing some searching on the net for an HO alternator and the biggest i think ive found was like a 160A, from what people say i need at least a 200A, ive checked mean green but the site didnt say they had honda alts
