Anyway guys I bought the sub's, they are pretty great. They are two Alpine Type S sub's , 10" each, mint condition and the box is nice. They do pound hard. Now I am going to get an amp that's probably around 1000W / 500 RMS. I talked to an audio shop and they told me that I would need a capacitor (100$), the 4 gauge wiring (70$) and the labour totaling about 400$. This is crazy, can I just buy a cheaper 4 gauge amp kit somewhere else? Do I need a capacitor?
