Hi, planning on installing a 15" Treo SSI D4 in my GF's car. I'll be able to put about 850w to it at 2ohm. Will 850w get the sub moving pretty good? Also, what box would be optimum for this woofer? I have a design for 3.25^ft @ 35hz, but this box is too tall to fit under the crossbar, so I'll need to rethink that.
Any opinions/answers would be greatly appreciated!
