Actually, going over some ideas. It will probably go like this 1-15 > 1-18 > 2-18.
It really depends on how efficient they are. I'd like to keep the single ZX2500.1 as my only power, if it looks like 2 on the amp is a no-go, I'll probably then consider a single 21".
I'm not really worried about the meter since my plan is to try and get this soloX 12 to a 150 for street A.
