I know this is an old thread, but i took my time to buy and put things together. I did a lot of research and before i go ahead and do the installation this spring, i want to make sure I have everything that i need to move forward.
Here's a list of things that I have at the moment
Alpine PDX-V9
Audiocontrol LC7I
NVX XKIT44
Infinity Kappa 682.11CF (already installed in all 4 doors)
I will be tapping into the speaker wires at the door (front and rear) instead of going behind the head unit. I'm also planning to run new speaker wires from the amp to the speakers. I am aware that our alternator is 150 AMP but considering that my 5 channel amp is 800 W RMS/1600 W max power, will i be required to install a capacitor? I believe that with the system installed, i will be needing at least 100 AMP from the alternator. This is the calculation I've been using (800 RMS (AMP) + 400 (sub) / 12) = 100 AMP (not sure if i should have added the sub in this calc) . Will that put too much strained on the alternator?
​Finally the speakers are 2 ohm and the sub i have is 4 ohm, will that be a problem?
Pls advise
