I am pretty sure that I want to purchase a SA-12 for my truck. It's almost time for me to use the money, but should I be reconsider a different sub ? I listen to rap and was thinking of just use the standard custom 35 hertz ported box. Will be using 900 watts . And don't want to spend over $200 for the single setup. I guess im looking for more SPL. I know 900 watts and a single sub isn't going to make records. I just want it to bump good. I'm going to be buying a new sub. Not buying used. Thanks for any suggestions.
