well narrowed down my new amp to a jl audio 1000/1 which will be here shortley and will be using jl sub, would using this amp be too much for a 12w7 or should i get a 13w7, its ok to overpower a sub a little huh
You could use a 12W7 and be ok IF you're careful, but personally I think you should go ahead and get the 13W7, more surface area, more excursion, SQ is about the same. You'll also utilize the power better.
