Okay so I am building a budget system.... I have chosen to purchase one SA 12 sub. I need some advice on... 1. Purchasing a 2ohm or 4ohm sub? 2. What size box should I have my shop build for me? (I am looking for good quality sound that is pretty loud for a daily driver, Listen to mostly hip hop) 3. Will a Arc FD600.1 amp be enough to power this sub adequately? Thanks a lot for your help!
