I was just cruising around on the interwebs and realized that when I upgraded my system, I didn't do the big 3 upgrade. I am running 2 10" subs of a little 350 Watt kenwood amp and my doors are from an Alpine PDX F4 400 Watts. Don't laugh at my subs (but suggestions are welcome). I have gone this whole time without the big 3 upgrade. Would you guys recommend I do it? And if so, tips/tricks?
