I just picked up a new Memphis Mojo 12" sub to go under the steering wheel. i will post some pics when I get around to building the box. I am putting it in a 3.5 cubic foot ported box. Its gonna be hard to get it down there but I took measurments and I think it can be done. I already wired in the amp. its a mtx 1000d. I will be running it at 2 ohms. the amp is rated at 1000 watts rms at 4 ohms. and is stable to 2 ohms. This thing should pound. I have burned up an alpine type R and a JL audio W6v2. So I hope this Mojo will take all that juice
