LOL! That's such a completely logical piece of advice I can't believe it never occured to me.
It's gonna be a while before I actually get the sub, right now I'm pretty sold on a DC Lv4 or a Death Row, so saving up for the thing will take some time. Might not even happen before the end of the year.
I have one amp, ordered another, need to get the HU and comps first. My plan is to have every single piece of equipment ready and then go to the shop and have them install everything at once, plus a Big3 upgrade and maybe a new battery. That way there's no need to pull things out more than once.
