opinions on new sub choice

[mwarmy33976 10+ year member]

Im stuck between 2 build ideas in my grand prix. First the back seat is coming out. The power source will be a Crescendo BC5500 with 4 runs of - and 4 runs of + with a D3400 up front and 2 D3100s in the back with a mechman 270 amp alt. I havent settled on box designs yet so those are still up in the air. Now the choice is between 4 SA 15s or 2 18" shocker sigs. If so just please state your opinion and why THANK YOU

Zcon because they are monsters and can take a good amount of power

You could talk to SPLaudio and get two beefy custom subs built.

The only thing im worried about is if the power will be enough for the sigs. I dont want to underpower them

I've ran sigs on 400rms, you won't underpower them. They are still better then the others even on less power.
