I am planning to upgrade my amp for my 2 HCCA 12's. I only have a 4-gauge power and ground with 2 1-Farad caps. I may get 2 Ultimate Sound Digitalis DD1-1300S's and wire each amp to a 1-ohm load on each 12. Would these be hard on my electrical system? Same question for the DD1-1200 as well? Otherwise, I will get a MMATS D300HC amp and run @ 2-ohms.
