Re: I have a kac-8101d 1000w how to i set it to get the most out of it
I don't think alpine has ever listed max power so I think he has a lidgit 750. And his subs are not good but much better then yours. You need to set the gain right, 75% does not mean 75% power. See where it's at then and go from there. Personally I would start over, whoever told you that's a good amp don't know what they are talking about.
