Caps are garbage and have no use for anything other then have lil kids with big shinny 100$ tubes. I would not go jl overpriced by far!! Ma Audio will not do rated power no matter what it says or anyone says period and might last 6months. Ed would be a better choice even though my two nine 1's did not do there rated power (the were pre production 1st gens) they have gen 2's out now so im sure they fixed that problem and there priced right.
