Even dual 3-inch is too big in my opinion. You'll likely lose a bit of low end. Do your wallet a favor and run dual 2.5 inch up through the bed and then slip the five inch over it, keeping the 2.5 inch tips below the top of the 5-inchers so only yu will know. You get the look without any loss of low end.
