I think I may keep it in the 14 - 15 volt area cause my amp is 14v stable I dont see anything more than that so I dont think I will risk it going any higher thanks to everyone who offered advice.
Well I have a xs power 16v s1000 already just want to see the proper way to hook it up..but im goin with 2 atomic 3ks and I have a 250 ho alternator im thinking about going up to a 350
