Can the sundown x8 be mounted in a box right against the wood almost like .25 inches away from magnet touching wood cause I know they don't have a hyperpole I'm gonna run 3 at 1.75 cubes tuned to 34 on 2500
those subs will do very well if you want to get a high # , not so much for daily sound quality though , they are a bit peaky , the sa v3 for daily SLAM
but I would shoot for 3000 watts on 3
and 1.75 cubes net is too small
2.25 Min net
better at 3 cubes net
you can set your box up like this , port to drivers side
