105 amp stock alt...

[MrWizzard 10+ year member]

Alright, my Stock Alt is 105 amps, i want to go cheap as possible for the electrical if i have too...

I'll be running a XXX 12" 4 ohm DVC, on a zapco C2K 6.0 bridged into 2ohms (its either 900 rms or 1300 rms, i got conflicting info off zapco, hehe)... i'll proabably be running 100x2 for comps passive or 100x4 for 2 way active comps... (undesided on that one)

So, with that, will the stock alt be good, along with replacing the main batt with a yellow top, or should i add the yellow top as an extra battery and if i do, will 105 amp alt have enough to charge both? or should i just keep the stock battery and get a new HO Alt or should i just get a HO alt and change the stock battery? or change to a H0 Alt and "ADD" another battery? lol

Got a few options, not sure wich one will be best for the setup. So i just want a few opinions from someone who's tried various configs with about the same power...

Should be around 1500 watts or so including the HU etc... (and assuming an Active 2 way comp setup).

I guess that alt should give me about 1300 watts at 13v or so... enough or not enough? hehe.

Thanks for any opinions....

FYI, I will be doing the big 3 of course....

what kind of vehicle are we talking about? 105 amps isn't anything too bad, my scion had a 40 amp stocker.. : / 105 will get you where you need to go, just upgrade the big 3 and go with the yellow top and see where you're at once you install the stereo, that'd probably be the cheapest way... but definately replace the battery if it's a stocker from the dealer, unless it's already a decent battery, then just do the big 3 and you should be on your way to something good.

post up some pics if you do an install on that alternator though : ) //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

the 105 will be fine. Add your yellow top and you will be good.

Kewl, its an 03 alero, and the replacement alt is a 105 amp, so i assume its 105 amps or so... not even sure if its stock or not since it was 1 year used but it most likely is still stock.
