im plannnin on running 2 Fi Q 18 in a sealed 10.5 cubic ft box i finished this weekend, my problem is my alt. i kno i need to upgrade but it will probably come as a gift and i think i will get about a 160 amp alternator, and since im running about 2000 watts rms is there any way to make up for my alternator deficiency like running extra batteries or several capacitors? thanks
nope. caps can "mask" your alternator problems for some time, but will eventually just harm it in the long run. the batts (extra batts for the back im assuming) will only be good when you have a good alt to push them
