Well I have been building a system. I have been thinking some things over. If I went with two Fi car audio SSD 12's I think it would be retardedly loud and I would need a battery. Now if I went with one Fi SSD 15 I think it would be just as if not louder than two JL 12 W3s which I had in my last car. My question is will this amp work Alpine MRD-M605 and which SSD model would I need to get?
