Im stuck between an SSD and an AA Arsenal which one is geared more for spl and can get lower and louder.

Both solid subs, but the better question is how much power do you have? The SSD is 800W RMS for the standard version and the Aresneal is 500. I think they are pretty equal in terms of SQ and general ability when used within their limits.
