Question on electrical

[mwarmy33976 10+ year member]

Well i have a grand prix, sadly, with the 3.8 N/A. I just got my tax check back and im planning my system. I already have the woofers ordered, 4 15 AQ HDC3A, and I was planning on running 2 3500.1s on them. I'm in the process now of taking my back seat out and building my platform, but I just now realized a problem I overlooked. The 3.8 engine has little to no extra space so dual alts is deffinatley out of the question, yet I think I need dual alts. I called Ohio generator and talked to the owner and he said the biggest Alt he can get me for the grand prix is a 300 amp alt. Will that be enough to power the system? Im running 6 XS D3400 batts and right now just 4 runs of 0 ga (thinking of doubling that?). Will the 300 amp alt be enough to keep my voltage up? or should I just cut the power? Any input will be greatly appreciated.

Okay your looking at a 380 amp fuse rating per amp. I dont know how efficient these amps are because ive never ran em. With the 300 amp alt and 390 Ah of batteries your still a little short of the max draw that your gonna pull. I did say max draw. Your not gonna play your system wide open for long periods of time I would assume. So with the electrical you stated in your first post I think you should be more than safe. Just hook it all up, put a DMM on your amp and slowly roll your volume while watching your voltage drop. If your voltage stays up then your good. The volume knob is what gets alot of people in trouble. If your still lacking I would look at getting some 3100's or some Batcap 4000's. Thats just my .02 cents bro.
