I have a 1200 watt amp a pryamid pb 800sx and i want to put it on my new gm car so i need to use a line out converter whats better a PAC OEM-2 Universal Premium Sound System Interface, or a PAC SNI-35 Line Out Reducer or a, Legacy LN-60 Line Out Reducer. I think that first one is not going to work but thats a guess because it doesnt reduce i need to know if they need more that one rca in the reducer since i have such a big amp
