I traded my Mofo 12" for 4 Power Acoustik 10"s in a box. But my amp messed up 3 of the 4 10"s. (it's a pos Optimus Amp). ANYWAY, what speakers provides the best bass for 1^3ft(A cubic foot) of air per speaker? I was going to buy 4 new ones and a new amp. I'm putting it in my dakota as a temporary system. I planned out the 4 12"s I'm going to put in my dakota(scrapped ideas on the durango and am going to sell it) I guess I'm more of a truck guy anyway. I was thinking about $200-300 for all 4 subs at the most. So whatever can give me the best sound in that box (sealed) would be great. Also, need an amp.. I'm going to blow mine up. lol. Unless you want it? It's a 260w Optimus, 4ch. NOT 2ohm stable evidently lol. only 3 ch. work now, I dunno. It's messed up. Maybe you (98) can cut me some kind of deal if I give it to you? lol. It's easy to fix(from what I'm told) I just don't feel like messing with it.
