Need some help on electrical!!

[ccrider540]

Im getting a 300 amp alternator for my 99 suburban and i was wondering if that would be enough for my system. I have 1 hifonics bxi2610D that im planning on running at 2600 watts and a hifonics zxi6410 for 4 channel for that runs at 170 x 4 channels. All i have is a yellow top under the hood so i wanted to know if i would need a second battery or if i should get a capacitor. And there might be a chance that i will get another bxi2610D over summer and run both at 1700watts rms instead of 2600 watts. So it would really appreciate some help on this from everyone because im clueless.

300 amp and yellow top should be enough for a BXI2610D since it's not actually going to put out 2600RMS (more like 2000) the 300AMP is plenty and the yellow top should keep charged, you MIGHT need an additional deep cycle or batcap but I doubt it.

I wouldnt use a capacitor. get a second battery. or a third. then check your voltage when the subs are going

get a second battery 300 amp alt will be enough

I'd say get a group 34 optima in the back, do 1\0 and big 3 in knukonceptz, and you'll be all set.
