I'm not sure if this is the right section so I apologize..
I have a 240 amp mechman alternator and a kinetic 1800 battery as well as the big 3 upgrade. I'm running 2 FI Alphas on a Rockford Fosgate 1200 and 4 door speakers on a Rockford Fosgate 250. At idle the rpms drop (roughly 300 rpms give or take) when the bass hits at high volume. I'm not really sure what's causing this as I tried to take the necessary sets to prevent this with the HO alt and battery ect..
And here I was thinking I had enough juice to add a second RF 1200 so each sub has its own amp.
Any ideas as to what's causing this voltage/rpm drop?
